• t (offset)
• Calibration evaluation:
• +: Successful calibration.
The new calibration data are taken over for measurement.
• -: Calibration unsuccessful.
Sensor blocked for measurement.
4.2.5 Reactivating the last valid calibration
If a manual calibration procedure is unsuccessful, the measuring oper-
ation can only be resumed after the manual calibration was repeated or
a valid calibration was reactivated.
If an automatic calibration procedure is unsuccessful, the analyzer
stops. To be able to measure again, you have to carry out a valid cali-
bration procedure in the calibration and service menu, or to reactivate
a valid calibration.
Thus you can immediately continue to measure if a calibration failed or
you suspect that the calibration conditions were not optimally met.

Reactivating old calibration data is a temporary measure.
Take into consideration that the sensor my provide wrong
measured values. Ensure the correct functioning of the
sensor by checking and/or recalibrating it.
