Analog Output Error State
GMP231 sets the analog output channel into a defined error level instead
of the measured result in two situations:
- Probe detects a measurement malfunction. This means an actual
measurement problem, such as sensor damage or unsuitable
environmental conditions.
- Measured value(s) are well outside the scaled output range. For a
more detailed explanation, see section Analog Output Overrange
Behavior on page 19.
The default error level depends on the output type:
- For 4 ... 20 mA output, the default error level is 3.6 mA
- For 0 ... 20 mA output, the default error level is 23 mA.
The probe resumes normal operation of the analog output when the cause
of the error state is removed.
