3.3.1 Measurement checking sensors during fault tracing
1.
Disconnect the relevant sensor from I/O-card/terminal block.
2. Measure the resistance for the sensor and any extension cables.
3. Then measure the sensor only.
Note! To ensure the sensor value the actual temperature must be checked against the measured
resistance.
