Hello,
I bought two meters from ebay the other day both are insulation resistance meters. The digital one is faulty, I put in fresh batteries and nothing. No battery check light or anything. I want to fix it but not to sure how to fault find. I took it apart and had a look at the capacitors, nothing had popped or swelled. There doesn't seem to be any sign of burning anywhere or poor solder joints. I want to fix this thing, how could I go about it. Please do not answer four year degree course or read a massive book like the art of electronics. I think that measuring voltages around the circuit may be a start. However, recently I tried to fix my signal generator, the 1kHz velleman kit. There is no output, the circuit works up to a point on the board but it doesn't get to the output. I am not sure if a capacitor may be the problem.
The insulation resistance meter is 12 volts. I think I know enough about safety to not shock myself or possibly blow something up. What suggestions for fixing this thing. There are a few chips on the board.
Any advice would be great!
Thanks
Simon
