Error State
If the voltage supplied to the DMT132 is too low for reliable operation,
or there is some serious problem that prevents measurement, the
DMT132 will enter an error state. The error state is indicated by the
following:
- Analog current output is set to the error level (default is 3.8 mA)
- If the LED indicator plug option is installed, the LED is blinking.
- Serial line outputs asterisk characters "*" instead of measurement data
for the SEND command. For example:
>send
Tdf= ***.**'C
>
- The
ERRS
command returns the currently active error code(s).
For example:
>errs
Error: E2 Humidity sensor open circuit/not calibrated
>
NOTE
The analog output levels for the error state are configurable using the
AERR
command; see section Set Analog Output Error Notification on
