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?
