(1) separate the sensor and the background object by a distance of 20 mm min. (2) cover the surface of the background object with a material with a small reflection factor, such as black sponge. 4. after setting the sensitivity adjuster to point c, check if the light indicator is lit on placing the sensing object at the sensing position and not lit on removing the sensing object. background object a background object b background object black paper with small reflection factor c b c point a point b check sens- ing condi- tions ad- juster indi- cator adjustment procedure 1. set the sensitivity of the photomicrosensor to minimum, place the sensing object at the sensing position, turn the sensitivity adjuster clockwise slowly until the light indicator is lit (point a). 2. set the sensitivity adjuster at the center (point c) between points a and b (the point where the sensitivity is maximum). 3. after setting the sensitivity adjuster to point c, check if the light indicator is not lit on removing the sensing object. a b c a c
