Micronta 22-220 FET multimeter calibration?
(1/2) > >>
BeBuLamar:
I have this old Radio Shack Micronta 22-220 which kind of a Simpson 260 wanna bee. It does have the FET front end to provide 10 MOhms input impedance for the DCV. There are a couple of potentionmeter inside which I believe for calibration. Does anyone know how to do the calibration on this thing? Besides I couldn't even find a user manual for it. I am sure I have the user manual somewhere but I can't find it. I bought it new sometime in the early 80's.

All you have to do is Google your question and you will find the answer to this. I just did and in a matter of 30 seconds it was solved. No I'm not going to give you the link because you will benefit more from doing it yourself.

I don't understand why people don't do that first before limiting their search to one forum on the internet.  :-\
BeBuLamar:
I've spent hours searching the web and find nothing but a schematica diagram. No service manual or user's manual. Thank you very much for nothing.
AVGresponding:
Elektrotanya and RadioMuseum are the places to look for things like this
BeBuLamar:
I looked both and none was found except that is the schematic diagram.
