Syntax:
*TST?
Description:
Power Supply test.This query causes the power supply to do a self test and provide the controller
with pass/fail results. A 0 is returned if the unit passes the test. If the unit fails, a number from 1
through 128 is returned to indicate the cause of the error. The test executes each of the subtests even
when any one fails. If any test fails an error code bit is set which is returned to the user. The error
codes returned are listed in Table A-4
