The operation of the analog outputs can be tested with the ATEST command by forcing the output to a given value which can then be measured with calibrated multimeter. The command uses the currently selected analog output types for the channels (voltage or current) so you do not have to specify the unit.

Before testing, you can verify the currently set analog output modes using the AMODE command. After testing the output, give the ATEST command again to exit the test mode.

Table 1. ATEST command
Syntax Description
ATEST [xxx yyy]<cr> Enter the test output values for channel 1 and channel 2.
xxx
Channel 1 output value (V or mA)
yyy
Channel 2 output value (V or mA)
The output shows the test values of the analog channels as well as diagnostic information that may be useful to Vaisala Service Center if there is a problem with the analog outputs.
