7.5.8 Calibration Mode: Data Entry
Entry of values for the cell factor and zero point of a sensor, related to 25 °C/77 °F.
If concentration measurement is activated (TAN option FW-E009), the concentration is also shown in
this menu and directly adjusted with the cell factor. This makes direct calibration to the concentration
value possible.

When you access calibration, the calibration values selected in the calibration presettings are used.
These settings can still be changed in the Calibration menu. If you do not want to perform calibration,
use the left
softkey
to go back one level and abort the calibration.

The calibration record is displayed. By pressing the
right softkey: Adjust
, the calibration values
obtained during calibration for calculation of the process variables are applied to the device.
When using a Memosens sensor, the calibration values are saved in the sensor.
7.5.9 Calibration Mode: Temperature
Adjustment of the Temperature Probe
This function is used to adjust the individual temperature probe tolerances or cable lengths for the
purpose of increasing the accuracy of the temperature measurement.
The adjustment requires an accurate measurement of the process temperature using a calibrated ref-
erence thermometer. The measurement error of the reference thermometer should be less than 0.1 K.
Adjustment without an accurate measurement may result in falsification of the displayed measured
value.
When using Memosens sensors, the adjustment value is saved in the sensor.
