Corrective Action

PC12 TEMP.AD See PC8 corrective actions. If all items check out properly, replace Input PCB

Assembly. Transmitter can be used; however, the Temperature Compensation must be

set to Manual and a Temperature Calibration should be conducted in order to set the

Manual Temperature Value close to the operating conditions.

Calibration Diagnostic Messages

The transmitter performs automatic efficiency and

offset calculations relative to a theoretically perfect

conductivity and/or temperature sensor during each

calibration cycle. Calibration history is retained for

future interrogation using the Edit Calibrate State.

The calibration constants that are displayed are Slope

and Offset for the Process Variable and Temperature.

A Slope of less than 0.2 or greater than 5 indicates a

potentially bad process calibration point or poorly

performing sensor. In these cases, the text string

BAD.CAL (bad calibration) is displayed in the

secondary display region. The user is returned to the

beginning of the calibration cycle after the bad

calibration has been reported.

An Offset value of less than -20 µS/cm for Sensor

Group A, -4 µS/cm for Sensor Group B, and -0.800

µS/cm or greater than 20 µS/cm for Sensor Group A,

4 µS/cm for Sensor Group B, and 0.800 µS/cm for
