Periodic verification of measuring & testing equipment

Before using the measuring or testing equipment, most inspectors will verify if it is in good condition, this is good practice. However they do not re-verify its condition till the inspection is completed.

I take hi-pot tester as an example, and inspection time is from 10am-12pm in the morning, (lunch time: 12pm -1pm), and 1pm to 5pm in the afternoon. I would recommend to verify the condition of hi-pot tester at 10am, 12pm, 1pm, 3pm and 5pm.

If hi-pot tester is found not in good condition, the products which have been tested in the last period shall be isolated and re-tested with a good hi-pot tester. e.g. you found the tester is not at good order and could not detect non-conformed products at 3pm, then the tested products during 1pm-3pm shall be re-tested.

P.S.: fault simulator is normally used to verify if the measuring & testing equipment is in good condition.
