Default Re: Comark Early 1905 Insulation Meter Checks

I had my 1602 calibrated by RS a while ago and and it sailed through. I think that both my Comarks were dumped by the RAF when they acquired more modern digital stuff and I was lucky to stumble on to them at rallies. Of course, back in the days when I was a student, the old Comarks were regarded as 'A1' pieces of kit, so I was delighted to find them. As yours were owned by your dad, that's an additional reason for appreciating them!

Incidentally, when I first had problems with the 1905, and before I got the circuit via the forum, Comark advised that they no longer supported this old kit and couldn't help out in any way.
