Description
Meter body temperature is too high.
Zero calibration value is too large (shift is larger
than characterization).
SPAN correction factor is outside the acceptable
limits for accurate operation.
Transmitter is operating as current source.
Input pressure is more than two times greater
than the Upper Range Limit of the transmitter.
Must recalibrate transmitter to attain required
accuracy.
No temperature compensation data exists for
calculations
Description
You have connected to a device that has a newer
revision of device description than what is in the
communicator.
The transmitter poll address is not 0 (zero). You
