Electrical Safety & Function Tester. V. 154.

I have just obtained a Clare V.154 "P.A.T" tester.

It has a flash test facility at 3000V or 4000V and a large test probe that looks like a 50s sci-fi film ray gun. I will thoroughly service the instrument before use, and am not inclined to use the flash test facility, but am curious about how it produces the high Voltages. I have not opened the instrument yet so it will be a treat to have a look inside. Circa 1984 I believe.

I have a V.154 and can confirm the flash test voltage is derived from a small transformer. It's actually AC coming out of the probe. I do still use the flash test on equipment that's been repaired/modified. Absolutely lovely bit of kit

Yes it certainly is a lovely piece of sold hand made test gear. And when I opened it up to look inside the smell of old transformer varnish was wonderful. A piece of working history. I just love moving coil meters.
