Test Analog Output
The operation of the analog outputs can be tested with the
ATEST
command by forcing the outputs to given values which can then be
measured with a calibrated multimeter. After testing the outputs, give the
ATEST
command again to exit the test mode.
ATEST
[
ch1
] [
ch2
]<cr>
where
ch1 =
Analog output value for channel 1.
ch2 =
Analog output value for channel 2.
The command 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, set level to 0 for both
channels):
atest 0 0
0.000 81
0.000 79
Example (disabling analog output test mode, resuming normal output):
atest
