Operation HandyLab 200 4.4.5 Determining the cell constant (calibration in control standard) Why determine the cell constant? Aging slightly changes the cell constant, e.g. due to 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).
