8. Instrument Verification
Verification
is the process by which an instrument’s failure detectors are proven to be
functioning properly by performing basic tests in open and short circuit conditions.
Verifying the failure detection circuitry of the electrical safety tester is required by
safety agencies such as CSA, UL, and TUV.
NOTE:
Verification should be performed at the beginning of each day or each shift,
before testing has begun.
