Levell TM14 Insulation Tester
Hi!
I have finally after several years hunting, won one of these Levell TM14 instruments, so the first job on the agenda will be to redraw Levell's "kiddie scribbles" into something a little easier and clearer to read!
I do have a layout diagram of the PCB for one of these, but as I'd sneaked it out of a former employer, I felt unable to post it whilst they were still in business!
Now they are no more (Telford sold me a couple of T & M books with their library filing labels on them!) there is no longer any reason why this shouldn't be posted now, so I'll get it scanned as soon as I find it!
This diagram has the diode and transistor types on it which I know Members have been after!
I am certainly curious as to why Levell used "J" as the circuit reference for transistors tho'.
