• Calibration procedure of HEATHKIT IM-2202

    From Bo-Lennart@21:1/5 to All on Thu Feb 10 23:57:32 2022
    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!
