The calibration history contains the following information:
 Date of the calibration
 Relative Slope (dimensionless)
 Rating of the calibration:
– o.k.: Calibration was successful.
The new calibration values are used for the measurements.
– Error: Calibration was not successful.
The Sensor is blocked for measurement.
4.2.4 Reactivation of the last valid calibration
The TriOxmatic
®
700 IQ (SW) enables you to reactivate the last valid
calibration when needed. Thereby, it is possible to continue with
measurements, when a calibration failed or it is assumed that optimal
calibration conditions were not met.
Note
The reactivation of former calibration data is only a temporary solution.
Please consider, that thereby possibly wrong measurement values are
produced. Please check correct functioning of the sensor by performing
a function check and/ or a user calibration.
