Test Analog Output
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]
where
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 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

Set LED Indicator Level
Use the ALARM command to change the dewpoint temperature above
which the LED indicator plug is lit. The currently measured quantity is
used. You can also disable the LED indicator.
ALARM [on/off] [limit]
where
on/off = Enable (on) or disable (off) the LED indicator
function.
limit = Dewpoint temperature above which the LED
indicator is lit. Range -20 ... 50 °C.
Example (show the current status of the LED indication):
>alarm
Alarm Led : OFF
Alarm level : 20.000000
