LED. 5.2 CALIBRATION The AMC-1044-T series monitor is factory calibrated at levels based on set standards. As the calibration procedure may cause the monitoring equipment to give a false alarm, appropriate precautions should be taken. Instructions on introducing the gas sample are included with the sensor/transmitter manual.
Page 15 AMC-1044-T Monitor Example: Full scale = 100 ppm Low alarm trip = 35 ppm (35/100 x 4 VDC)+1 = 2.4 VDC High alarm adjustment is done in the same manner as above, using the high alarm adjust and measuring between COM and HIGH TP.
