*TST?
*TST?
The self-TeST query *TST? makes the instrument perform a self-test and place the results of
the test in the output queue. If the self-test fails, the results are also put in the error queue.
We recommend that you read self-test results from the error queue. No further commands
are allowed while the test is running. After the self-test the instrument is returned to the set-
ting that was active at the time the self-test query was processed. The self-test does not re-
quire operator interaction beyond sending the *TST? query.

4 Selftest failed on Slot 4
3 Selftest failed on Slot 3
2 Selftest failed on Slot 2
1 Selftest failed on Slot 1
0 Selftest failed on Slot 0
If 16 is returned, the module in slot 4 has failed.
If 18 is returned, the modules in slots 1 and 4 have failed.
A value of zero indicates no errors.
