10 2.3 before you begin 2.3.1 site preparation each r82 radar transmitter is built to match the physical specifications of the required installation. make sure the antenna connection is correct for the threaded or flanged mounting on the vessel or tank where the transmitter will be placed. see mounting, section 2.4. make sure that the wiring between the power supply and radar transmitter are complete and correct for the type of installation. when installing the radar transmitter in a general purpose or hazardous area, all local, state, and federal regulations and guidelines must be observed. see wiring, section 2.5. 2.3.2 equipment and tools no special tools are needed. the following items are recommended: ? threaded antenna and transmitter . . . . . . 2" (50 mm) ? flat-blade screwdriver ? digital multimeter or volt/ammeter . . . . . optional ? 24 vdc (23 ma) power supply. . . . . . . . optional 2.3.3 operational considerations radar applications are characterized by three basic conditions; dielectric, distance (measuring range) and disturbances (turbulence, foam, false targets, multiple reflections and rate of change). 2.3.3.1 maximum distance the chart at left shows the maximum measuring range (distance) based on fundamental conditions of dielectric, distance and turbulence. maximum distance is calculated as tank height + sensor offset (see page 20). it is measured from the sensor reference point (bottom of npt thread, top of bsp thread or face of a flange). 2.3.3.2 minimum distance if the liquid level is allowed onto the antenna, noise and media build-up drastically decrease reliable measurement. liquid should not be allowed closer than 15 inches (380 mm) from the bottom of the antenna mounting threads (or face of hygienic flange). the distance from the end of the antenna varies depending on antenna chosen. see figure 8. 58-610 model r82 radar transmitter dielectric turbulence r82 1.7-3.0 none 26 (8.0) light, < 0.5" 21 (6.4) moderate, < 1.0" 14 (4.3) heavy, > 1.0" 7 (2.1) 3.0-10.0 none 33 (10.1) light, < 0.5" 26 (7.9) moderate, < 1.0" 19 (5.8) heavy, > 1.0" 12 (3.7) 10.0-100 none 40 (12) light, < 0.5" 32 (9.8) moderate, < 1.0" 24 (7.3) heavy, > 1.0" 17 (5.2) maximum distance feet (meters) figure 7
11 58-610 model r82 radar transmitter 2.3.3.3 problematic applications; gwr alternative some application concerns can be problematic for radar. for these, guided wave radar is recommended: ? extremely low dielectric media ( r <2.0) ? very weak reflections from the liquid surface, particularly during turbulence, can cause poor performance. ? tanks heavily cluttered with false targets (mixers, pumps, ladders, pipes, etc.) ? during times of very low liquid levels of low dielectric media, the metal tank bottom may be detected deteriorat- ing performance. 2-inch (50 mm) antenna 8-inch (200 mm) antenna 13" (330 mm) 7" (178 mm) 15" (380 mm) minimum (measured from bottom of threads or flange face) 2-inch (50 mm) antenna maximum recess ( m ) is 2 nozzle diameter ( d) (example: 2" diameter nozzle) 8-inch (200 mm) antenna maximum liquid level maximum liquid level m d 15" (380 mm) 2" (50 mm) 4" (100 mm) 15" (380 mm) 8" (200 mm) 9" (225 mm) 3" (75 mm) 4" (100 mm) d :8fc6 %:?:>f> 5:de2?46 e@ 6?5 @7 2?e6??2 g2c:6d 56a6?5:?8 @? 2?e6??2 fd65 :8fc6 -d:?8 ?@kk=6 96:89e e@ >2i:>:k6 fd623=6 e2?< da246
12 58-610 model r82 radar transmitter ? foam can either absorb or reflect the microwave energy depending upon the depth, dielectric, density and wall thickness of the bubbles. due to typical variations in the amount (depth) of foam, it is impossible to quantify per- formance. it may be possible to receive most, some or none of the transmitted energy. ? extremely high liquid levels (overflow) conditions when liquid very near the antenna (above the blocking distance) can cause erroneous readings and measurement failure. 2.4 mounting the r82 radar transmitter can be mounted to a vessel using a variety of process connections. generally, either a threaded or flanged connection is used. 2.4.1 installing the transmitter before installing, make sure: ? process temperature, pressure, dielectric, turbulence and distance are within the antenna specifications for the installation. ? end of antenna is protected from bending or breaking. ? insulating material is not placed around any part of the radar transmitter including the antenna flange. ? transmitter is being mounted in the optimal location. see following sections: location, beam angle, obstructions and nozzles for specific information. 2.4.1.1 location ideally, the radar transmitter should be mounted provid- ing an unobstructed signal path to the liquid surface where it should illuminate (with microwave energy) the largest, possible surface area. see section 2.4.1.2, beam angle. unavoidable obstacles will produce reflections that must be minimized during field configuration. see section 2.6.5.1, target rejection. mount in a location equal to 1 M 2 the radius of tank top. do not mount in center of vessel nor closer than 10" (25 cm) from the tank wall. 2.4.1.2 beam angle ideally, the beam pattern should illuminate the maximum liquid surface with a minimum striking other objects in the vessel including the tank wall. 1/2 radius > 10" (25 cm) w distance beam spread feet meters feet meters 10 3 2.5 0.74 20 6 4.9 1.47 30 9 7.4 2.21 40 12 9.8 2.95 figure 10 figure 11
13 58-610 model r82 radar transmitter 2.4.1.3 obstructions almost any object that falls within the beam pattern will cause reflections that may be misinterpreted as a false liquid level. although model r82 has a powerful echo rejection routine, all possible precautions should be taken to mini- mize false target reflections with proper installation and orientation. see figure 12. 2.4.1.4 nozzles improper installation in a nozzle creates ringing which will adversely affect measurement. two antenna extension lengths are offered to allow the r82 transmitter to work reliably in a variety of nozzles. the minimum blocking distance of 15" (380 mm) is always measured from the bottom of the threads or face of the flange. the related distance as measured from the end of the antenna varies depending on the antenna extension chosen. see figure 13. the narrow beam width of the 26 ghz, r82 does allow mounting so that the antenna can be recessed inside the nozzle. optimally, the recessed dimension should never exceed 2 the nozzle diameter . see figure 13 note: if the antenna is recessed in a nozzle it is mandatory that echo rejection is run to eliminate any possibility of false reflections. 2-inch (50 mm) antenna maximum recess (m) is 2 nozzle diameter (d) (example: 2" diameter nozzle) 8-inch (200 mm) antenna maximum liquid level maximum liquid level m d 15" (380 mm) 2" (50 mm) 4" (100 mm) 15" (380 mm) 8" (200 mm) 9" (225 mm) 3" (75 mm) 4" (100 mm) d :8fc6 g@:5:?8'3decf4e:@?d :8fc6 -d:?8?@kk=696:89ee@>2i:>:k6fd623=6e2? 14 58-610 model r82 radar transmitter 2.4.1.5 stillwells the r82 can be mounted in a stillwell but certain consider- ations should be given: ? metal stillwells only: 2" (50 mm) sched 40 max. ? diameter must be consistent throughout length; no reducers. ? stillwell length must cover complete range of measurement (i.e., liquid must be in stillwell). ? welds should be smooth. ? vents: holes <0.125" diameter, slots <0.125" width. ? if an isolation valve is used, it must be a full port ball valve with an i.d. equal to the pipe diameter. ? bridles/bypass installations: the launcher should be rotated 90 from process connections. ? configuration must include an entry for pipe i.d. see section 2.6.6.2, item 34- pipe i.d. 2.4.2 installing the transmitter install the transmitter with its integral antenna by threading into the vessel. do not overtighten as this may cause damage to the plastic threads. ? do not place insulating material around any part of the radar transmitter including the antenna flange. ? installation for nema 6p/ip 68: the lexan ? housing can be installed to allow for temporary submergence to 6.5 ft. (2m) for 24 hours: - use tfe paste to seal conduit entries or ip 68 cable glands - do not overtighten plastic housing cover; o-ring develops water-tight seal without excessive tightening 2.4.2.1 orientation the r82 transmitter utilizes a linearly polarized, microwave beam that can be rotated to improve its performance. proper orientation can minimize unwanted reflections, decrease sidewall reflections (multipath) and maximize direct reflections from the liquid surface. the internal launcher mechanism can be turned to optimize performance. the launcher has index marks numbered 1C 18 (representing 10C180 degrees). the polarization pattern is parallel to the transmitter display when the adjustment mechanism is in the #11 position (factory default). see figures 15 and 16. figure 14 r82 mounted in stillwell (bridle) ground launcher adjustment in #11 position (default) figure 16 polarization pattern tangent line figure 15 launcher adjustment in #11 position (default)
15 58-610 model r82 radar transmitter 2.4.2.2 initial installation ideally, the transmitter should be mounted half the radius from the tank wall. in a typical vertical tank, the launcher should be adjusted so the polarization pattern is parallel to a line tangent to the nearest tank wall. see figure 16. rotate the internal launcher adjustment to achieve the correct polarization position. remember each notch on the adjustment wheel is 10 degrees of rotation. see figure 17. for horizontal cylindrical vessels, aim beam down the long axis of the vessel. do not optimize the echo strength at one level in the vessel. a transmitter mounted within 10" (25 cm) of a tank wall may demand orientation adjustments to limit multipath and optimize performance. see section 2.4.2.3, poor echo strength. 2.4.2.3 poor echo strength poor echo strength has many potential causes. following are two initial areas for investigation. launcher orientation: initial launcher orientation is always parallel to tangent of the tank circumference (see sections 2.4.2.1 & 2.4.2.2). in tall vessels and when antenna is mounted close to the tank wall, improvement in echo strength may be attained by rotating the launcher to 90 degrees. signal loss: if the level signal is lost repeatedly at a specific point in the vessel, it is usually a symptom that multipath (side-wall reflections) are causing cancellation by returning to the transmitter exactly 180 out of phase with the level signal. utilize the following procedure: ? go to transmitter screen #5 which shows both level and echo strength. ? bring the level up (or down) to the exact point where the signal is repeatedly lost. monitor the echo strength this point is being approached. the echo strength will degrade to a low point before it begins to increase. ? at the poorest echo strength slowly rotate the launcher 1C2 notches. allow the unit to stabilize for approximately one minute. repeat this process until the echo strength is optimized. figure 18 internal launcher adjustment figure 17 examples of launcher orientation adjustments ground launcher adjustment (+) (-) 90 degrees: rotate launcher mechanism cw 9 notches 30 degrees: rotate launcher mechanism clockwise (cw) 3 notches 30 90 tangent line
16 58-610 model r82 radar transmitter 2.5 wiring wiring between the power supply and the radar transmitter should be made using 18C22 awg shielded twisted pair instrument cable. within the transmitter enclosure, con- nections are made to the terminal strip and the ground connections. trim excess wiring to minimize clutter, noise issues and allow access to launcher adjustment. see figure 19. the directions for wiring the radar transmitter depend on the application: ? general purpose or non-incendive (cl i, div. 2) ? intrinsically safe 2.5.1 general purpose or non-incendive (cl i, div. 2) a general purpose installation does not have flammable media present. areas rated non-incendive (cl i, div. 2) have flammable media present only under abnormal conditions. no special electrical connections are required. if flammable media is contained in the vessel, the transmitter must be installed per cl i, div. 1 standards of area classification. to install general purpose or non-incendive wiring: 1. remove the cover to the wiring compartment of the trans- mitter. install the conduit plug in the unused opening. 2. install a conduit fitting and pull the supply wires. 3. connect shield to an earth ground at power supply and leave floating at the transmitter. 4. connect an earth ground wire to the nearest green ground screw per local electrical code (not shown in illustration). 5. connect the positive supply wire to the (+) terminal and the negative supply wire to the (-) terminal. 6. seal conduit to prevent ingress of moisture. 7. replace cover of the transmiter. 2.5.2 intrinsically safe an intrinsically safe (is) installation potentially has flam- mable media present. an approved is barrier must be installed in the non-hazardous (safe) area. to install intrinsically safe wiring: 1. make sure the is barrier is properly installed in the safe area (refer to local plant or facility procedures). complete the wiring from the barrier to the radar transmitter. 2. remove the cover of the transmitter. install the conduit plug in the unused opening. 3. install a conduit fitting and pull the supply wires. 4. connect shield to an earth ground at power supply and leave floating at the transmitter. ground (+) (-) figure 19 wiring the transmitter caution: the r82 radar transmitter operates at voltages of 16C36 vdc (gp) and 16-28.6 vdc (is). higher voltage will damage the transmitter. notes: ? if sufficient supply voltage is suspect, use the r82 low voltage check (section 2.6.6.1, #37: test 4-20 loop). ? for atex installation guidelines refer to bulletin be 58-610.
17 58-610 model r82 radar transmitter 5. connect an earth ground wire to the nearest green ground screw (not shown in illustration). 6. connect the positive supply wire to the (+) terminal and the negative supply wire to the (-) terminal. 7. replace the cover of the transmitter. 2.6 configuring the transmitter the radar transmitter comes factory-calibrated and can be configured in minutes for specific applications. before configuring the transmitter, collect the operating parameters information. then, power-up the transmitter on the bench and follow through the step-by-step proce- dures for the menu-driven transmitter display. information on configuring the transmitter using a hart communica- tor is given in configuration using hart (section 2.7). 2.6.1 operating parameters some key information is needed to configure the radar transmitter. if necessary, complete the configuration infor- mation table in section 1.1.2. 2.6.2 setting up for shop configuration the radar transmitter can be configured at a test bench by connecting a 24 vdc power supply directly to the trans- mitter terminals. the connections are illustrated in the accompanying diagrams. an optional digital multimeter is shown if current measurements are desired. when using a hart communicator for configuration, a minimum 250 line load resistance is required. see the hart communicator manual for more information. 2.6.3 transmitter display and keypad the r82 transmitter has a local user interface consisting of a 2-line 16-character liquid-crystal display (lcd) and 4-push-button keypad. all transmitter measurement data and configuration information is shown in the lcd. the transmitter default display is the measurement screen. it cycles every 2 seconds to display *status*, *level*, *echo strength*, *%output*, *loop cur- rent* and *local tag* information. the transmitter defaults to this display after 5 minutes if no keystrokes are sensed. you can also access each of these screens individu- ally. the display will not return to the default screen if left in one of these screens. for example, the device can be left to display only level indefinitely if left in this screen. ground launcher adjustment (+) (-) figure 20 display and keypad
2.6.4 menu traversal and data entry the four push buttons offer various forms of functionality for navigation and data entry (i.e., navigation, data selection, etc.). 2.6.4.2 data selection use this method for selecting configuration data from a specific list. an arrow will appear when in the data selection mode. see figure 21. use the following procedure: ? up an down arrows to navigate the main menu ? enter arrow to allow modification of selection ? up an down arrows to choose new selection ? enter arrow to confirm selection ? use back (escape) key at any time to abort the proce- dure and escape to previous branch item. 2.6.4.3 entering numeric data using digit entry use this method to input numeric data, e.g., sensor offset. 18 58-610 model r82 radar transmitter push button keystroke action up moves to the previous item in the menu branch down moves to the next item in the menu branch back moves back one level to the previous higher branch item enter enters into the lower level branch or switches to the entry mode 2.6.4.1 navigating menu push button keystroke action up moves up to the next highest digit (0,1,2,3,....,9). if held down the digits scroll until the push button is released. down moves down to the next lowest digit (9,8,7,6,.,0). if held down the digits scroll until the push button is released. back moves the cursor to the left and deletes a digit. if the cursor is already at the leftmost position, then the screen is exited without changing the previously saved value. enter moves the cursor to the right. if the cursor is located at a blank character position, the new value is saved. notes: all numeric values are left-justified,and new values are entered from left to right. a deci- mal point can be entered after the first digit is entered, such that .9 is entered as 0.9. some configuration items can have a negative value. in this case, the leftmost position is reversed for the sign (either "-" for a negative value, or "+" for a postive value). figure 21 figure 22
19 58-610 model r82 radar transmitter 2.6.4.4 entering numeric data using increment/decrement use this method to input the following data: damping, echo loss delay, trim level, trim 4 ma, trim 20 ma, test 4-20 loop and hart poll addr. 2.6.4.5 entering character data this method is used for entering alphanumeric charac- ters, e.g., input local tag. push button keystroke action up moves to the previous character (z,y,x,w). if held down the characters scroll until the push button is released. down moves to the next item character (a,b,c,d). if held down the characters scroll until the push button is released. back moves the cursor back to the left. if the cursor is already at the leftmost position, then the screen is exited without changing the original tag characters. enter moves the cursor forward to the right. if the cursor is at the rightmost position, then the new tag is saved. push button keystroke action up increments the displayed value. if held down the digits scroll until the push button is released. depending on which screen is being revised, the increment amount may increase by a factor of 10 after the value has been incremented 10 times. down decrements the displayed value. if held down the digits scroll until the push button is released. depending on which screen is being revised, the decrement amount may increase by a factor of 10 after the value has been decremented 10 times. back returns to the previous menu without changing the original value, which is immediately redis- played. enter accepts the displayed value and returns to the previous menu. figure 23 figure 24
20 58-610 model r82 radar transmitter 2.6.5 password protection (default = 0) the radar transmitter is password protected to restrict access to certain portions of the menu structure that affect the operation of the system. the password can be changed to any numerical value up to 255. the password is required whenever configuration values are changed. the default password installed in the transmitter at the factory is 0 (password disabled). the last step in the config- uration menu provides the option to enter a new password. if 0 is entered as a password, the transmitter is no longer password protected and any value in the menu can be altered (except diagnostic values) without entering a con- firming password. note: if the password is not known, the menu item new password (section 2.6.6.1, item #39) displays an encrypted value repre- senting the present password. call the factory with this encrypted value to determine the actual password. 2.6.6 menu: step-by-step procedure the following table provides a complete explanation of the software menus displayed by the radar transmitter. use this table as a step-by-step guide to configure the transmitter. the first column presents the menus shown on the trans- mitter display. the displays are in the order they would appear if the arrow keys were used to scroll through the menu. the numbers are not shown on the display. they are provided as a reference only. the second column provides the actions to take when configuring the transmitter. additional information or an explanation of an action is given in the third column. figure 25 provides reference to the configuration procedure. use of the included pact ware ? pc program is highly recommended and invaluable for troubleshooting and advanced calibration. a hart rs232 or usb modem (purchased separately) is required. see magnetrol pact ware ? bulletin 59-101. tank height sensor offset + tank height = distance from process connection to tank bottom 20 ma 4 ma sensor reference point sensor offset (+) blocking distance distance safe zone media level level offset lowest measurable value highest measureable value figure 25

27 58-610 model r82 radar transmitter 2.7 configuration using hart ? a hart ? (highway addressable remote transducer) remote unit, such as a hart communicator, can be used to provide a communication link to the model r82 transmitter. when connected to the control loop, the same system meas- urement readings shown on the transmitter are shown on the communicator. in addition, the communicator can be used to configure the transmitter. to confirm hart hand-held communications, attach unit per section 2.7.1. if communicator reads generic on first two lines, the hart hand-held does not contain the current dds (device description) for the model r82 radar transmitter. contact your local hart service center and specify a magnetrol model r82 device descriptor. see hart revision table, section 2.7.3. 2.7.1 connections a hart communicator can be operated from a remote location by connecting it to a remote junction or by con- necting it directly to the terminal block in the electronics housing of the modelr82 transmitter. hart uses the bell 202 frequency shift key technique of high-frequency digital signals. it operates on the 4C20 ma loop and requires 250 load resistance. a typical connec- tion between a communicator and the model r82 transmit- ter is illustrated. 2.7.2 display menu a typical communicator display is an 8-line by 21-character lcd. when connected, the top line of each menu displays the model (model r82) and its tag number or address. usually the bottom line of each menu is reserved for soft- ware-defined function keys (f1Cf4). for detailed operating information, refer to the instruction manual provided with the hart communicator. the model r82 transmitter online menu trees are shown in the following illustration. open the menu by pressing the alphanumeric key 1, device setup, to display the second- level menu. + - junction r l > 250 ? control room display power supply current meter hart version hcf release date compatible with r82 software dev v2, dd v2 april 2009 version 1.0a and later 2.7.3 hart revision table 2.7.3.1 model r82

30 58-610 model r82 radar transmitter 3.0 reference information this section presents an overview of the operation of the model r82 radar level transmitter, information on trou- bleshooting, common problems, listings of agency approvals, lists of replacement and recommended spare parts, and detailed physical, functional and performance specifications. 3.1 description the model r82 is a two-wire, 24 vdc level transmitter based on the concept of pulse burst radar operating at 26ghz. the electronics are mounted in a metal or plastic housing with an innovative, internal launcher orientation mechanism. 3.2 theory of operation 3.2.1 pulse burst radar the model r82 is a top-mounted, downward-looking pulse burst radar operating at 26 ghz. unlike true pulse devices that transmit a single, sharp (fast rise-time) waveform of wide-band energy, the r82 emits short bursts of 26 ghz energy and measures the transit time of the signal reflected off the liquid surface. distance is calculated utilizing the equation distance = c transit time/2, then developing the level value by factoring in tank height and sensor offset information. the exact reference point for distance and level calculations is the sensor reference pointbottom of an npt thread, top of a bsp thread or face of a flange. distance = c (time ? 2) 1 ns 500 ns npt process connection bsp process connection hygienic pulse pulse burst figure 26 figure 27 sensor reference point
31 58-610 model r82 radar transmitter the exact level measurement is extracted from false echo reflections and other background noise via the use of sophis- ticated signal processing. the new r82 circuitry is extremely energy efficient so no duty cycling is necessary to accom- plish effective measurement. for this reason, the r82 can track high rates of change that were heretofore impossible with existing loop-powered radar transmitters. 3.2.2 equivalent time sampling ets, or equivalent time sampling, is used to measure the high speed, low power em (electromagnetic) energy. ets is a critical key in the application of radar to vessel level measurement technology. the high speed electromagnetic energy (1 ft/ns) is difficult to measure over short distances and at the resolution required in the process industry. ets captures the em signals in real time (nanoseconds) and reconstructs them in equivalent time (milliseconds), which is much easier to measure with todays technology. ets is accomplished by scanning the tank to collect thou- sands of samples. the round-trip event on a 40-foot (12.3m) tank takes only 82 nanoseconds in real time. after it is reconstructed in equivalent time it measures 135 milliseconds. tank height sensor offset + tank height = distance from process connection to tank bottom 20 ma 4 ma sensor reference point sensor offset (+) blocking distance distance safe zone media level level offset lowest measurable value highest measureable value figure 28
32 58-610 model r82 radar transmitter 3.3 troubleshooting the model r82 transmitter is designed and engineered for trouble-free operation over a wide range of operating conditions. common transmitter problems are discussed in terms of their symptoms and recommended corrective actions. warning! explosion hazard. do not remove covers unless power has been switched off or the area is known to be non- hazardous. use of the included pact ware ? pc program is highly recommended and invaluable for troubleshooting and advanced calibration. a hart rs232 or usb modem (purchased separately) is required. see magnetrol pact ware ? bulletin 59-101. symptom problem solution level reading drops out at a repeatable position in the vessel multipath is cancelling good level signal orient launcher to reduce multipath; turn launcher 10C20 degrees (1C2 index marks) at a time until multipath at this point disappears. refer to section 2.4.2.3 level reading locked onto a value that is not correct measurement engine finding a reflection it believes is level signal 1. is high dielectric ( >10) foam present? 2. run echo rejection routine with level below this point (or with empty tank) to eliminate false echoes level, % output and loop values are all inaccurate basic configuration data questionable 1. check validity of all configuration data 2. check distance value of device against manually measured distance level readings are repeat- able but consistently high (or low) from actual by a fixed amount configuration data does not accurately match tank dimensions 1. ensure proper values for tank height and sensor offset 2. check vessel for present liquid level. trim level can be used to ensure exact measurement 3. reconfigure loop values if necessary level reading on display is correct but loop is stuck at 4 ma hart poll address set a value of 1-15 set hart poll address to 0 level reading on display stuck at value related to blocking distance device believes antenna is flooded (level very near or on antenna) check actual level. if antenna is not flooded, power down, then power up transmitter with the level well below the antenna. 3.3.1 troubleshooting system problems
33 58-610 model r82 radar transmitter 3.3.2 error messages the model r82 radar transmitter utilizes a 3-section hierarchy for reporting diagnostic conditions: faults, warnings, and information. faults and warnings will be shown in the home screen when the message is active. a chronological listing of messages can be viewed in the history screen. fault: the highest level in the hierarchy of diagnostics annunciating a defect or failure in circuitry or software that precludes reliable measurement. the current (ma) value unit defaults to 3.6, 22, or hold and the home screen will freeze showing the highest priority fault. a chronological listing of messages can be viewed in the history screen. warning (message): the second level in the hierar- chy of diagnostics annunciating conditions that are not fatal but may affect measurement. the highest priority warning will be placed on the main (rotating) screen when a warning is detected but will not affect output current. a chronological listing of messages can be viewed in the history screen. information (message): the lowest level in the hierarchy of diagnostic conditions providing operational factors that are not critical to measurement. a chronological listing of messages can be viewed in the history screen ma loop display message history screen fault 3.6/22/hold yes yes warning no effect yes yes information no effect no yes effects of each diagnostic message also listed in history screen are changes of "state". for example, "bc level" which means boundary condition level. this is an expression of the transmitters internal logic.
