Chosen Solution
I tested an electric fence with my Fluke 77 series II. Bad idea. Now I can’t read AC/DC voltage or amperage, or resistance. I’ve replaced the fuse. I’d appreciate any assistance.
@tlampros I guess the good thing that even for a meter there are manuals :-). Start off with the flowchart as designed by Fluke
After that, download 77 Series III and see if you can find out what happened to your meter. Looks like U1 could be the issue
