What does it mean when my Honeywell Transmitter is in 'Fixed Current Mode', and how do I change it?
If your Honeywell Transmitter is in 'Fixed Current Mode,' it means the output current is fixed and not varying with the applied input.

If your Honeywell Transmitter displays 'Meter Body NVM Corrupt', it means the Meter Body NVM data has been corrupted. Try resetting the device. If the problem continues, replace the Meter Body.
What to do if the Honeywell Transmitter displays 'Mbd Com (Meter body Comm fault)'?
If your Honeywell Transmitter displays 'Mbd Com' (Meter body Comm fault), check the ribbon cable that connects the Meter body to the Electronics Module. Ensure that the cable is securely plugged into the Electronics Module and that all pins are properly connected. Cycle power to the transmitter. If the problem continues, replace the Electronics Module. If this does not fix the problem, replace the Meter body.
What to do if the Honeywell ST 700 displays 'Meter body Comm fault'?
If your Honeywell Transmitter shows a 'Meter body Comm fault', it means communication between the Meter body and the Electronics Module has failed, possibly due to a module failure or the connecting cable. First, inspect the ribbon cable connecting the Meter body to the Electronics Module to ensure it's securely plugged in and that all pins are properly connected. Then, cycle power to the transmitter. If the issue persists, replace the Electronics Module. If the problem remains after that, replace the Meter body.
What to do if Honeywell ST 700 displays 'Fault. A critical failure has been detected in the Meter body'?
If your Honeywell Transmitter displays a fault indicating a critical failure in the Meter body, cycle power to the Transmitter. If the problem continues to occur, replace the Meter body.
How to fix 'Meter body Critical Failure' on Honeywell Transmitter?
If your Honeywell Transmitter displays 'Meter body Critical Failure', this indicates a critical failure reported at the sensor level. You should first try to reset the device. If the problem continues after the reset, replace the Meter Body.
What does 'Electronic Module DAC Failure' mean on my Honeywell ST 700 Transmitter, and how do I fix it?
An 'Electronic Module DAC Failure' on your Honeywell Transmitter indicates a failure in the Electronics Module, possibly due to the board temperature exceeding 140C, under-current or over-current status, packet error, SPI fault, or control word write fault. Begin by verifying that the environment temperature is within specified limits. Then, reset the device. If the problem persists, replace the Electronics Module.
What to do if my Honeywell ST 700 displays 'Sensor Comm Timeout'?
If your Honeywell Transmitter shows a 'Sensor Comm Timeout' error, it means there's likely no response from the sensor. First, try replacing the Electronics module. If the issue continues, then replace the Meter Body.
What to do if a critical failure has been detected in the Meter body of Honeywell ST 700?
If a critical failure has been detected in the Meter body, cycle power to the Transmitter. If the problem continues to occur, replace the Meter body.
