Robin Insulation Tester
 

Not quite vintage, but hopefully useful in this hobby.

I inherited this along with several decent multimeters and clamp meters from my father who was an industrial electrician and sadly died far too young, and before I got into this hobby. I'm sure he would have loved seeing what I was up to...

Unfortunately I don't have the leads for it. Could anyone tell me what to look for in finding replacements?

They seem like standard robin multimeter leads, except they need to be quite long as the terminals are recessed. I don't have the unit in front of me right now but there is a stock picture attached.

I've never used one of these before but it looks quite straight foreward and seems to be able to apply voltages up to 1000 vDC.

Thanks
Adam
