Operation Cond 3210 4.4.5 Determining the cell constant (calibration in control standard) Why determine the cell constant? Aging slightly changes the cell constant, e. g. by coatings. As a result, an inexact measured value is displayed. The original characteristics of the cell can often be restored by cleaning the cell. Calibration determines the current value of the cell constant and stores this value in the meter. Thus, you should calibrate at regular intervals (we recommend: every 6 months).
Cond 3210 Operation Determining the cell constant For this calibration procedure, the Measuring cell setting must be set to cal in the measuring menu. Proceed as follows to determine the cell constant: 1 Connect a conductivity measuring cell to the measuring instrument. 2 In the measured value display, select the conductivity parameter with . 3 Start the calibration with .
