The operation of the analog output can be tested with the ATEST command by forcing the output to a given value which can then be measured with a calibrated multimeter. After testing the output, give the ATEST command again to exit the test mode.
ATEST [mA]<cr>- mA
- Analog output value, range 0 ... 30 mA.
The output shows the test value of the analog output as well as diagnostic information that may be useful to Vaisala Service Center if there is a problem with the analog outputs.
Example (enabling analog output test mode with 20 mA output):
>atest 20
20.000000, 536b
>
Example (disabling analog output test mode, resuming normal output):
>atest
