(Self-Test Query)
*TST?
COMMAND
This query causes an internal self-test; the response indicates whether
any errors were detected.
When the self-test fails, error -330 is generated, and other messages
indicating specific failures are also placed in the error/event queue.

Programming Guide
Numeric data transferred as ACSII bytes in <NR1> format.
A response value of zero indicates the self-test has completed with no
errors detected, while a non-zero value indicates the self-test was not
completed or was completed with errors detected. The test failures
that can be detected and their corresponding bit numbers are shown
below:
The decimal weight of each bit is 2
