The accuracy of the conductivity measurements is influenced by:
• the drift of the zero point of conductivity. Correct the drift of the zero point with the function ZERO CALIB. To
be done if the conductivity of the air measured by the conductivity sensor is higher than 10 µS/cm (see "Calibrate the zero point of conductivity (function "Zero Calib." of the menu "Probe")", page 56).
• the conductivity cell constant:
- determine the cell constant of the sensor used with the function CALIBRATION (this calibration updates the
last calibration date in the “Last cal. date” function of the CALIB INTERVAL sub-menu hereafter). See "Calibrate the conductivity sensor (“Calibration” function in the “Probe” menu)", page 57,
- or enter the cell constant (marked on the calibration certificate of the device) in the function CELL CONSTANT. The entering of the cell constant does not update the last calibration date in the “Last cal. date”
function of the CALIB INTERVAL sub-menu. The function CELL CONSTANT makes it also possible to read
the value of the constant which has been determined with the function CALIBRATION.
• the correction factor of the fitting. Enter the correction factor related to the fitting S020 used in the function
