3.3. Cell cables

Compensation of the cable length
To minimize the effect of the cable resistance in a conductivity measurement, the cable length is compensa-
ted by the 4-wire system. With the Pt 1000 temperature sensor, the cable resistance has little importance.
However, in order to reduce the resistance of the conductor to a half, 2 cables have been connected to
the ends of the sensor.
