Troubleshooting Commands

Display the Currently Active Errors

Use the ERRS command to display the currently active transmitter error

states. Possible errors and their causes are listed in Table 11 on page 52.

Example:

errs

No errors

Test Analog Outputs

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.

ATEST [xxx yyy]<cr>

where

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, and diagnostic

information that may be useful to Vaisala Service if there is a problem

with the analog outputs.

Example:

atest 1 15

1.00 2660

15.00 19425

atest

0.00 79

0.00 20110

1 2 ... 36 37 38 39 40 41 42 43 44 45 46 ... 74 75
