The following data cannot be edited:
￭ Electrode test (only with intelligent sensors)
Result of the electrode test.
￭ Calibration temp
Temperature at which the calibration was carried out.
If the temperature was measured manually during the calibration, then
(manual) will also be displayed. If the temperature was measured with
a connected temperature sensor, then the sensor type ((Pt1000) or
(NTC)) will be displayed.
￭ Calibration date
Date and time of the last calibration. For new sensors, the time the
preparation was made is specified until after the first time a calibration
has been carried out.
￭ Cal. method
Method with which the sensor was calibrated. If the calibration data
was entered manually, then manual will be displayed.
￭ User
User who carried out the calibration.
￭ Measuring input (only with intelligent sensors)
The type and the serial number of the measuring input with which the
calibration was carried out.
