Warning
Caution, risk of electric shock. Instructions must be followed to avoid danger to
persons.
This unit puts out a hazardous voltage and must only be used by a qualified person and in
accordance with these instructions. If the equipment is not used in the manner described
the protection provided by the equipment may be impaired.
Check that the instrument is free from moisture, grease and dust before use.
Do not use if the unit is damaged in any way.

Clean only with a dry cloth do not use solvents.
There are no user replaceable parts inside
– do not open other than for replacing batteries.
To access the batteries, undo the two screws at the rear of the unit and remove cover.
Batteries should be disposed of with compliance to current recycling and disposal
regulations.
To ensure the safety of personnel working on electrical circuits, BEST PRACTICE
calls for the use of a proving unit before working on dead circuits.

– 690V proving unit with just two terminals to test AC and DC voltage detectors
Fast response and works with low impedance voltage testers
Ramps down through voltage levels
LED indication of functioning unit
Instructions
1. Test your voltage detector on the proving unit, by placing the
probes into the front terminals.
2. The LED on the proving unit should light up and your voltage
detector should indicate voltage present.
3. Continue to hold your voltage detector in the front terminals of
the Kewprove 3 and the voltage level output will fall in steps to
400V, 230V, 100V & 50V to prove these levels of voltage.
4. Prove your voltage detector is still working by placing the probes
into the front terminals again.
5. The LED on the proving unit should light up and your voltage
detector should indicate voltage present.
6. Continue to hold your voltage detector in the front terminals of
the Kewprove 3 and the voltage level output will fall in steps to
400V, 230V, 100V & 50V to prove these levels of voltage.
