Keep device identity, served system, approval, test, repair, retest, inspector, and current authority guidance together.
Do not bypass, alter, or self-test a device.
Preserve the current test trail
Record the location, device type, model, serial number, served system, approval, last test, result, repair, retest, tester, report destination, and next required action when those facts are available. Do not bypass, alter, or self-test a device to complete the file.
Confirm current SPU, Public Health, certification, and building requirements before work.
