Description Causes the multimeter to perform a series of internal self-test.
Syntax TEST
Remarks • Always disconnect any input signals before you run self-test. If you
leave an input signal connected to the multimeter, it may cause a self-test
failure.
• If a hardware error is detected. the multimeter sets bit 0 in the error
register and a more descriptive bit in the auxiliary error register. The
display's ERR annunciator illuminates whenever an error register bit is
set. You can access the error registers using ERRSTR? (both registers'),
ERR? (error register only) or AUXERR? (auxiliary error register only).
• NOTE: The internal self-test checks all calibration constants and verifies
they are within the lower and upper limits.
• Related Commands: AUXERR?, ERR?, ERRSTR?
