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.

    Nice job Zoomup, however any repairs should be carried out by the manufacturer who would test the repair after completion before returning your nice yellow voltage indicator.

    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.

    They are probably no longer made so returning it may be impossible. The re-soldering of the tip was quite an easy job. The design is very simple. At least it is internally fused (100mA) so if  used  to test Voltage and you accidently push the continuity button the internals are protected. It is quite old. Inside it is only a row of L.E.D.s and associated resisters, a buzzer and a few other bits. It is not meant to be used for precise accurate readings.

    Antiques roadshow?

    I've just donated an analogue voltmeter in a 14" * 10" * 8" bakelite box. Now gone to a new home via the next car boot sale.

    I have one of those “Newlec” testers labelled Di-Log by the manufacturer, it was a free gift from my local electrical wholesaler and is possibly an older version.


    There is nothing about it that impresses me.
