Details/Resolutions
Possible causes:
•
Sensor Overload/Sensor Fault
•
Redundant Characterization Calculation
Error
•
Calculated pressure is above Upper
Transducer Limit (UTL).
Resolution:
Check range and, if required, replace transmitter
with one that has a wider range. Meter Body may
have been damaged. Check the transmitter for
accuracy and linearity. Replace Meter Body and
recalibrate if needed.
Possible causes:
Output current is fixed and not varying with applied
input. Loop current mode is disabled or Loop Test is
active.
Resolution:
Enable Loop Current Mode if it is disabled or exit the
Loop Test mode if active.
Possible causes:
Meter Body temperature is too high. Accuracy and life
span may decrease if it remains high.
Resolution:
Verify the environment temperature is within
specification. Take steps to insulate Meter Body from
temperature source.
Possible Causes:
ZERO or SPAN correction factor is outside acceptable
limits. INPUT may have been incorrect during
calibration or transmitter was in output mode during a
CORRECT procedure.
Resolution:
Check input pressure and be sure that it matches
calibrated range values (LRV and URV). Check Meter
Body. Perform an LRV or ZERO CORRECT
procedure followed by a URV CORRECT procedure.
Possible causes:
The Display has been disconnected or configuration
data has been corrupted.
Resolution:
Secure Display connections and recheck. If problem
persists, reset the device. If the problem still persists,
replace the Display
