AC Voltage Proving Units are designed to proof AC voltage detectors and AC voltage testers and used to determine whether devices under test are functioning correctly. The AC Voltage Proving Units are not calibrators and cannot be utilized for calibration. The HLV Series voltage units can be proving units on a momentary basis (press, check, release), verifying electrical instruments, detectors or other AC measuring devices.
