4. Check the HART address and
mA Output Action
(
Loop Current Mode
).
5. Check to see if a loop test is in process (the output is fixed).
6. Check HART burst mode configuration.
7. If related to a zero calibration failure, reboot or power-cycle the transmitter and retry the zeroing
procedure.
15.10.5 mAO consistently out of range
Cause
•
Incorrect process variable or units assigned to output
•
Fault condition if
Fault Action
is set to Upscale or Downscale
•
LRV and URV are not set correctly
Recommended actions
1. Verify the output variable assignments.
2. Verify the measurement units configured for the output.
3. Check the
Fault Action
settings.
4. Check the settings of
Upper Range Value
and
Lower Range Value
.
5. Check the mA Output trim.
15.10.6 Consistently incorrect mA measurement
Cause
•
Loop problem
•
Output not trimmed correctly
•
Incorrect measurement unit configured for process variable
•
Incorrect process variable configured
•
LRV and URV are not set correctly
•
mA Output Direction not set correctly
Recommended actions
1. Check the mA Output trim.
2. Verify the measurement units configured for the output.
3. Verify the process variable assigned to the mA Output.
4. Check the direction parameters.
5. Check the settings of
Upper Range Value
and
Lower Range Value
.
