Calibration procedure of HEATHKIT IM-2202...

[Bo-Lennart]

Hi all out there....
I\'ve got an old Digital multimeter that need an calibration.
It\'s a HEATHKIT model: IM-2202.
I found a schematic on the net, but no calibration procedure. I think I could find that in the construction manual. But I couldn\'t find that manual on the net.
Is there someone that have the calibration procedure, and would like o share it with me, I would be more than happy.

With the best greetings from SWEDEN

Hello:
You may want to check out the following heathkit groups:
https://groups.io/g/heathkit
https://groups.io/g/Heathkit-Radios

I mostly hang out in the Heathkit-radios group. Occasionally, someone post a request for docs on test gear. The members are very helpful.
BTW, you best hope that IC #201 (MK6013 ICL6013) does not die.....a quick search on google turn up empty/unobtanium
Best of luck!
