after correcting the cause.
Input mA Contact Honeywell Analytics' Service Department.
Indicates that mA input from sensor is less than 3 mA. Check wiring
between XNX and sensor. Also check the switches S3 and S4 are set
Input mA correctly. If the switch settings need to be change, power down the
transmitter before changing the switch settings. If wiring and switches
are okay, replace sensor.
constant current A/D Check that correct mV sensor type is selected. Check wiring between
input mV XNX and sensor. If sensor type and wiring are okay, replace sensor.
Current baseline Perform zero calibration. If problem persists, replace sensor.
