    All,

    Good morning to you. Just looking to see what proving unit to buy; do I go for big bulky Kewtech or pocket sized fluke PRV240.

    Any suggestions etc, greatly received.

    Cheapest one you can get, as long as it tells you that your testers are working then what does it matter? They're all over priced anyway.

    If by 'self proving' you mean say the Fluke T-150 which has a built in test function, all that does is prove the indicators work. It will not tell you the unit will successfully read say 240v on a cable and should not be used as a replacement for a standalone proving unit.

    A quote from Martindale:

    It is important to note that the voltage indicator MUST be able to work without the need for a battery, if you are using a device that needs a battery in order to work and the battery is flat, then you will not be able to prove if the circuit is dead or not.

    The procedure for proving dead is to take the voltage indicator and check it against a known source, such as a proving unit, then test the circuit, then test the voltage indicator against the known source again to prove the tester has not failed during testing.

    Whilst you can a known live source to test your voltage indicator, we recommend using a dedicated proving unit.

    The reason is that the known live source will only light some of the LEDs on the tester, whereas a proving unit will ensure that
    ALL LEDs on all ranges are working, again safeguarding against incorrect readings due to a blown LED.

    I addition there is not always a live source nearby.

    bad idea. if you grip it, you can't let go. best just to brush across it with said wet finger.

    If you had a proving unit you could use it before actually touching the live part, and then do it again just to prove it's live. A JOKE DIYers TAKE NOTE
