The calibration history provides the following information:
 Date of the calibration
 Slope [mV/pH]
 Asymmetry potential [mV]
 Calibration evaluation:
–
o.k.
: Successful calibration.
The new calibration data are taken over for measurement.
–
Error
: Calibration unsuccessful.
Sensor blocked for measurement.
4.2.7 Reactivating a valid calibration
The SensoLyt
®
700 IQ H provides a feature with witch you can reacti-
vate the last valid calibration if necessary. Thus you can immediately
continue to measure if a calibration failed.
Reactivating the
calibration data
Reactivating old calibration data is a temporary measure.
Take into consideration that the sensor may provide wrong
measured values. Ensure the correct functioning of the
sensor by checking and/or recalibrating it.
