Page 16: Operation And Calibration
The AMC-l022M series monitor is factory calibrated at levels based on set standards. Calibration of the monitor should be performed every 6 months, unless the alarm trip point settings need to be changed.
Page 17 AMC- - - - 1022M 1022M 1022M 1022M NOTE THE FOLLOWING PROCEDURE IS FOR REMOTE SENSOR ONLY. IF A TRANSMITTER IS USED, REFER TO ADJUSTMENTS IN CALIBRATION SECTION 3.2 IN THE APPROPRIATE TRANSMITTER MANUAL. The low alarm adjust is used to establish the low alarm trip point. This is done by exposing the sensor being calibrated to the low alarm gas concentration and adjusting the LO trimmer clockwise until the yellow LED just lights.
