Zero point calibration

cali. zero point
probe in air!
accept value?
12 μS/cm
IMPORTANT
• The zero point must be calibrated during commissioning.
• The zero point must be calibrated if the measurement range
is changed.
• Calibrate the zero point only when the sensor tip is completely
dry.
• Calibrate the zero point in the air when dismantled only.
• Hold the sensor tip more than 40 mm away from all objects
during calibration.
• Calibrate the zero point before the slope.
To calibrate the zero point of the sensor, dismantle the sensor
and then completely dry the sensor tip and the sensor shaft.
Select the first menu option in the "cali. zero point" in the setting
menu and wait approx. 30 s until the measured value is stable –
then press Enter.

Slope calibration

IMPORTANT
• Always follow the handling instructions below.
• During calibration the water sample must be flowing evenly
without bubbles or turbulence or at a standstill.
• If calibrating in flowing water, the electrolytic conductivity of
the water sample must be constant.
• The axis through the bore of the sensor tip must line up with
the direction of the flow.
