*TST? Self-test

Syntax: *TST?

Response: 0 1

0Self-test okay.

1Self-test not okay.

Description:

The *TST? query initiates a RAM/ROM test in the instrument and returns the result of the test. The result of the RAM/ROM test is 0, if the test is completed without detecting any error. If the result is 1, the self-test failed. Upon successful completion of *TST?, the instrument settings are restored to their values prior to the execution of *TST?.

Example:

Send → *TST? Read ← <result>

IF <result> = 1 THEN PRINT "Self-test failed; instrument must be repaired."
