I remember when I was at college and the lecturer was about to demonstrate how to use a wind-up insulation tester. He picked out one lad who had a looped earring in each ear. He proceeded to place a clip on each earring and gave the tester handle a little twitch............I didn’t know somebody could jump that high!!!!

Glenn, Some nice pictures there. I had a student bring one into class and we measured the output voltage and current. 426V at 1.6mA Still working and would still be, unofficially, suitable for the job

I still remember playing with my dads one of these 'when I were a lad'. It was aincient tech back then as well

Aye happy days, when testing was a shorter sequence .......polarity, earthing ,insulation, continuity (or as i was taught. people eat ice cream)

Oh the fun we had with these and a suitably gullible apprentice !!!
Apparently not allowed to do things like that anymore!

They're beautifully made pieces of equipment. I bought a couple a few weeks ago (posted pics here), not sure what they're worth but I get the impression there still quite a few of them around so probably not too much.

yeah..well the reason i posted these pics in here was because theres some images of the internal parts/construction....

Interesting pics, but any chance of posting larger file sizes, when I try to open the files, they come up postage stamp size?
