ZERO CORRECT procedure followed by a
URV CORRECT procedure.
Electronic Module Comm
Failure Possible causes:
There was a failure in the Electronics Module
communication section.
Resolution:
Verify the environment temperature is within
specifications. Reset the device.
If the problem persists, replace the

terminals is too low or the supply voltage to
the Sensor board is too low.
Resolution:
Check that the power supply and loop
resistance are within specification. If
possible, try to increase the voltage level of
the supply. If supply voltage and loop
resistance are adequate and the problem
persists, replace the Electronics Module. If
the problem still persists, replace the Meter
Body.
