Return transmitter to service and turn ON power.

Verify transmitter’s configuration data. Recalibrate transmitter to achieve highest accuracy; if this is not convenient, reset calibration (See Section 10.5 in this manual) for PV1 and PV2, and do an input zero correction for PV1 to compensate for any minor error. Also, check PV3 zero point.
