Calibration

Fig. 8.14 Overview
The measuring cell can be set via the menu CALIBRATION.
Please follow these steps for the calibration:
After entering to the sub-menu CALIBRATION the system
prompts for zero point measurement (probe in air).
Take the probe out of the unit and dry if necessary. Select
start measuring by pressing key ↵. The ongoing
measurement is indicated by a flashing star.
If the measurement values are stable for a certain time,
this measured value is accepted and the system prompts
for calibration measurement at the upper range value.
Grind in calibration resistance of 2,3 kΩ as indicated in
Fig. 8.18.
Start the measurement by pressing ↵-key.
The proceeding measurement is indicated by a flashing
star.
If the measuring value is stable for a certain time, the
measured value and both calibration measurements are
analysed. If the analysis is successful, then the calibration
is properly completed.
The values are saved by pressing the NEXT-Key.
If the analysis is negative or if one of the two
measurements within the time frame is unstable, the
calibration is cancelled.
The calibration values calculated till the abort are not accepted.
An accidentally started calibration can be cancelled at any time by pressing the NEXT-Key.
