Excess Span Correction
The SPAN correction factor is outside
acceptable limits. INPUT may have been
incorrect during calibration or transmitter was in
output mode during a URV 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.
Excess Zero Correction
The ZERO correction factor is outside
acceptable limits. INPUT may have been
incorrect during calibration or transmitter was in
output mode during an LRV or ZERO
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.
Sensor Over
Temperature
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.
