3.5.3 Connecting the cable to the sensor
Connecting the cable to the sensor
• Ensure that the cable and the electrode connector are absolutely dry 1.
• Screw the cable connector 2 on to the sensor 3 and tighten it by hand .
3.6 Calibrating the electrode
Before the electrode is installed, it has to be calibrated. Proceed as described on page 25. 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, clean it with pure water and then dry it with air (e.g. hair
blower).
