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.
N
To ensure the sensor value the actual temperature must be checked against the measured resistance.
