Newlec Voltage Tester.

Zoomup
I am the proud owner of a Newlec model NLVCT Voltage and continuity tester. It is a simple yellow coloured device with a solid probe and a trailing probe. It can test continuity and give a Voltage indication. Recently the rigid probe became loose and I had to re-solder it. After that the device would not work properly. Inside are two push switches. I later realised that the two switches need to be pressed together for some functions, but there is only one external button to press. It was at that stage that I noticed the internal bar that pushes on the two switches inside the body of the tester by means of the one external button. Doh!


I find it invaluable and would like another spare one. So if anybody has one I would be keen to buy it.


Thanks,


Z.

    I'd like to think you do a sanity check verification that it is working when you are about to use it in anger anyway. A repair by the maker's approved technician may be neater, but there is the same chance of something else coming detached internally in any case, much as there is with any other instrument. Like calibration, the value of the makers tests sort of rubs off once the kit has been bouncing about in the back of the truck for a bit, or has made an unplanned trip or two down the steps.

    If  the measurement matters, more than a quick go/no-go decision, then verify the instrument against another or on a known test load from time to time in any case. Mean while test the resistance range reads zero into shorted  leads and examine the case for dents/cracks each time you fire it up as a matter of course.
