Setting the calibration tolerances

Procedure

1. Main menu > "2. Settings" > "08. Calibrations" > "1. Setpoints, tolerances, purge

time" > "3. Calibration tolerances"

The settings of this menu cause the device to monitor the deviations of the zero point or

span point compared to the last calibration. The reaction to a tolerance violation is

different for validation tolerance and calibration tolerance.

Note

Tolerance violation

If the factory-set tolerance value is exceeded, the device outputs a maintenance alarm.

The indicated measured values are no longer valid:

• Evaluate the message text of the maintenance alarm. Remedy the causes of errors

mentioned in it, for example, incorrectly set setpoints.

• If the cause of a tolerance violation cannot be traced back to incorrect operator inputs,

contact the service department and take the device out of service.

– Authorize access with Expert PIN, if necessary.

– Enter the zero point in %. The percentage refers to the value of the smallest span.

Enter the span point in %. The tolerance in the span point refers to the span or the full-

scale value of the selected measuring range.
