BT DVM information.
Hopefully it's right place ,but if not please move.
I've had a few googles looking for info on the BT DVM modeled on the 8022 and finally found this link with a lot of information. https://www.google.com/search?q=fluk...HgayY7M:&vet=1 And a circuit diagram https://www.researchgate.net/figure/...fig2_312121646 On a closer look the first link has a lot more on Fluke stuff and other interesting topics. |

Re: BT DVM information.
The second link seems to bring up a DVM, but one based on a PIC and part of an automatic power transfer switch design. Radiomuseum has a circuit for the 8022B: https://www.radiomuseum.org/r/fluke_...ultimeter.html

Re: BT DVM information.
Thanks, Herald- still in the dark as my meter ,marked as 802xA on the PCB has only two visible electrolytic caps, both of 22u/16V . Any circuit diags for 8022(A/B) show a lot more electrolytic caps of varying value. As I've got a pair of 22/16 Tants, I think I#ll start there, but as DC volts show up as +30% and resistance shows up a 50% extra., I think that is a long shot.
