3.5.3 Connecting the cable to the sensor

Connecting the cable to the sensor

• Unscrew the protective cap from the sensor connector and keep it for future use 1.
• Ensure that both cable and sensor connector are absolutely dry 2.
• Make sure that the O-ring is positioned on the sensor connector 3.
• Screw the cable connector 4 on to the sensor and tighten it by hand.

3.6 Calibrating the sensor

Before the sensor is installed, it has to be calibrated. Proceed as described on page 27. Then
continue with the installation procedure.

CAUTION!
Moisture inside the sensor connector must be avoided! Moisture will shortcut the mV signal
between the electrodes and deliver erratic readings!
If moisture has entered the connector dry it with air (e.g. hair blower).
