The probe sets the analog output channel into a defined error level instead of the measured result in three situations:
- Probe is performing start-up purge (duration 4 minutes).
- Probe detects a measurement malfunction. This means an actual measurement problem, such as sensor damage, or unsuitable environmental conditions.
- Measured value(s) are outside the error limits defined for the outputs.
The default error level for the analog outputs is 3.6 mA. You can change the error level (range 0 ... 25 mA) with the Insight software and via Modbus (registers 0706hex and 0806hex).
