FS9912 standard code for 3,000 counts low cost scale application.
ADC displays 3 times per sec. 4 x 1.5V (or 3 x 1.5V) battery. Current consumption of the chip is less than 2mA. Current consumption of the scale system (e.g. 400 Load Cell) can be controlled to be less than 5mA through program skill. In Sleep Mode, chip current consumption is less than 1uA and the system current consumption (add low-voltage detecting circuit) is less than 5uA. 1/3 bias, 1/4 duty 4 x 16 LCD driver circuit (3V Vpp). 14-bit ADC resolution; scale external display accuracy: settable, maximum accuracy is 6553; default accuracy is 2000. SCALE: 2000g/1g (default), 2000g/1g (default), weight/verification-scale-interval is settable. Sleep Mode (auto turn off). If the scale is at Same Display in 2 minutes (default, time is settable), the system will turn off. Key functions: ON/OFF, ON/Zero/(Tare)/OFF, Tare, Mode and Net/Gross (SetPCS). Scale unit: g, Kg, Lb, oz, Catty (Taiwanese Kg), Tale (tl.T, Taiwanese Hg), ...(settable, 3 units for switching at most).

8. Operation Functions
8.1 Power-on Self-Checking Procedures:
All LCD signals light up when power on; the system is processing zero reset. If the zero point is not stable, it displays "Unst". TEST EEPROM(93c46): If there is no EEPROM or after changing EEPROM without recalibration or data loss (ChkSum error), it will display "ErrE" and the system automatically turns off 30 seconds later. If there is no parameter setting value in calibration, it will act with default value automatically and write the value into EEPROM. Power-on zero resetting range: <20%F.S. (default, can be set); if it is out of range, it displays "outZ". Power on low voltage detecting: The first low voltage is about vbat=3.6V (Voltage detection is settable. Please refer to section "Parameter Settings"). In this situation, a low voltage symbol is displayed and the scale still functions normally. Second low voltage is about vbat=3.5V (Active/disable and voltage detection are settable. Please refer to section "Parameter Settings"), the system will display a low voltage symbol, but the scale can not function and will automatically turn off 30 seconds later.
8.2 Display:
Display the limit of weight range: maximum weight = max. weight + 9d. The system displays "EEEEE" when overload. If the weight is less than 0, the value is displayed with a negative sign. Power low: When battery is low, the display shows a battery symbol. Zero symbol (ZERO): When scaled zero, the system displays ZERO. Tare symbol (TARE): When the scale is in tare situation, the system displays TARE. In this situation, ZERO cannot be displayed. After tare and remove the tare object to make the scale empty (ZERO and TARE displayed at the same time), the TARE symbol will be cleared if TARE key is pressed. A/DC output range testing: if the result is lower than the A/DC resolution range, it displays "LLLLL"; if the result is beyond the A/DC resolution range, it displays "HHHHH". The purpose of this test is when the input signal being abnormal, the system can detect the problem (such as Load Cell damaged).
8.3 ZERO Reset and ZERO Point Tracing
Zero point tracing means to trace the initial zero point, and only works under the display value being zero. Correction speed is settable. Range of zero point tracing: The sum of zero reset and zero point tracing must not be over 4% (default, settable) F.S. of the maximum scale.

8.4 ON/OFF Key
Semiconductor Corporation
FS9912 LCS2
FS9912 standard code for 3,000 counts low cost scale application.
Press the key to turn off during system is in power on status. (Turn off) Press the key to turn on during system is in power off status. (Turn on)
8.5 ON/ZERO/(TARE)/OFF Key
Press the key to turn on during system is in power off status. (Turn on) Zero (default): If the weight is less than 4% (default, settable) F.S., the system will do zero reset. Otherwise the system acts nothing. Zero/Tare Integration: If the weight is less than 4% (default, settable) F.S., the system will do zero reset. If it is over the range of zero reset, the system will do Tare action. Press the key (>3sec) to turn off during system is in power on status. (Turn off)
8.6 TARE Key
When the system is on, press this key, and the system will operate TARE function. The effect of TARE: The scale weight display = maximum scale - amount of tare. For example: the maximum scale of a scale is 2kg and the TARE amount is1kg, the scale will display 1kg + 9d. No TARE for negative value
8.7 MODE Key
Press this key to switch the weight unit in the power on status. (Unit 1 -->Unit 2 -->Unit 3 -->Pcs(Unit 4)). Mode Memory Function: When power off, the system will memory the current mode. When power on next time, the mode will be same as before power off last time. 1 oz = 28.349523125g. 1 Catty = 600g.
8.8 Net/Gross (SetPcs) Key
The function is to switch net weight and gross weight in general status. In Pcs status, push the SetPcs key, and it will switch sequentially S= 10, S= 20, S= 50, S=100, which means samples setup. Then push the "Mode" key, the LCD displays "CAL" that means the system is sampling.
8.9 RS232 transmission specification:
The first character is symbol code (ASCII code 30~3fh). Bit 0 means "ZERO" symbol, bit 1 means "TARE" symbol, bit 2 means "-"symbol, and bit 3 means battery symbol.

The second, ninth, and twelfth characters are space characters. The third to eighth characters are values (ASCII code). The tenth character is the first decimal symbol code (ASCII code "1" means integer, "2" means decimal one, "4" means decimal two, "8" means decimal three, "16" means decimal four.) The twelfth character is the second decimal symbol code ("0" means none, "1" means the decimal exist.) Other messages mean transmission ASCII code directly. For example, "unSt", "outZ", "ErrE", "EEEEE", ....

Hys_num[1:0]: hysteresis range setup. 00: 0.1, 01: 0.2, 10: 0.3, 11: 0.4. The hysteresis range is mainly for adding the stability of value. This value means to ignore the output if instant change does not exceed the set value. The Unit is external resolution (Counts). E_flag3: Power on zero reset range setup, 1~100%. Default value is 20. E_flag4: Default value is 00000000b. bit 7 6 5 4 3 2 1 0 E_flag4 D_power Z/T off_RS232 WU4_en no_Z M_Hold no_bat bat_I D_power: Cancel save power mode. No switch when measuring Load Cell power. Consumption current increased, but scale stability promoted. Z/T: Combination of Zero Key and Tare Key. off_RS232: Cancel RS232 transmission. no_Z: No zero reset when power on and take directly calibrated zero point as zero point. M_Hold: Hold maximum displayed value. Press any key to cancel. Cancel temporarily during return zero. no_bat: No low battery detection when power on. Take PT1.4 as low battery detection status input. "0" stands for low voltage. bat_I: ADC value of low battery detection when power on. "0" means using default value; "1" means using EEPROM parameter. A B C D 30H Lb1L Lb1H Lb2L Lb2H Lb1L, Lb1H: ADC value of the first low battery detection. Lb2L, Lb2H: ADC value of second low battery detection. WU4_en: Cancel PCS. Enable the fourth unit switch. The related parameter address is as follow: byte 0 12 3 4 5 6 7 8 30H E_flag4 Res4L Res4H W_min4 W_point4 W_ch4L W_ch4M W_ch4H The meaning of Default value: Calibration Unit: Main Unit is g. Calibration weight is 2000g. Power On Unit: Main Unit. Switchable Unit: Second Unit is Catty and Tale. Third Unit is oz, Simple Calculation (Pcs). Max. weight: Main Unit is 2000g. Second Unit is 3 Catties, 5.35 Tale. Third Unit is 80.00 oz. Overload display is current unit plus 9d. Min. weight: Main Unit is 1g. Second Unit is 0.05 Tales. Third Unit is 0.05 oz. Accuracy: Main Unit is 1g. Second Unit is 0.05 Tales. Third Unit is 0.05 oz. Unit switch (W_ch) parameter definition: Highest 4 bits mean integer; sequent 20 bits means decimal. They must be calculated with W_min and W_point. For example: 1g = 0.02666667 Tales = 0.03527396 oz g-> Tale = 0.02666667*2^20*10^W_point/W_min = 0.02666667*2^20*100/5 = 088888h g-> oz = 0.03527396*2^20*10^W_point/W_min = 0.03527396*2^20*100/5 = 0b49a4h 93c46 parameter settings can be changed by keys. Steps: Press and hold Mode Key (>3sec) when power on. The system will enter EEPROM and display "E:0E:55". LCD_T1 will lights up. "0E" means address and "55" means value. To press Zero Key, the address will plus 1; to press Mode Key, the address will minus 1. Press and hold Mode Key (>3 sec). The system will enter value change. LCD_T3 will lights up. To press Zero Key, the value will plus 1; to press Mode Key, the value will minus1. Press and hold Mode Key (>3 sec) to write the value, and return to " 2) ".
