Select CELL CONSTANT from the Configuration pull-down menu to view or change the conductivity reference temperature.
The setting can be changed by selecting the edit box and typing the desired number. To accept the change, click OK. To abort
the change, click CANCEL.
The value shown in the edit box is used as a calibration value. Changing it will change the measured value. If the sensor type
is a nominal 0.1 Cell for RESISTIVITY measurements, values can be changed from 0.05 to 0.15. If the sensor type is a nominal
1.0 Cell for low range conductivity measurements, values can be changed from 0.5 to 1.5. It is important to clean the sensor
electrodes in detergent that does not contain Lanolin or Aloe prior to calibration.
