ICT 2 Inductive Conductivity Sensor, Running-In
The sensor DULCOTEST
®
ICT 2 inductive conductivity can be readily used for further measures
such as calibration and measurement without requiring any running-in.

ICT 2 Inductive Conductivity Sensor, Calibration
Presettings
Check
fi rst that the sensor is correctly connected to the DULCOMETER
®
D1C (do not open the
sensor).
Check that the right sensor type has been selected.

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 fi rst 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.
