Hello guys, im not that kinda of electronic guy, so got some questions
i bough a Fluke 77 III, it was working fine, reading, but since i dont use it that often, i think it went months without use, but the other day I try to use it and it becomes crazy, it starts readings without reason, lcd numbers and letters are all moving, without measuring anything, sometimes i turned it off and suddently the lcd displays all the numbers a letters at once and it get stuck on it. any idea? see picture

Take the batteries out, wait a few minutes, then replace with brand new batteries. Hopefully that will fix it.
If not then it's probably not repairable.
Has it got damp while it been stored?
