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

page 39.
