Bricked Fluke 177
andyB2022:
I owe you guys some apologies, the 2.5M resistance was measured with a very dodgy meter, I've got this UNI-T 216C from a friend today to test again. Looks like the resistance between COM and V is infinite (above 60M at least, the maximum this clamp meter can measure)...
Second photo is to proof that the clamp meter measures correctly (tested it on a few 10k resistor too to make sure...)
So basically we are dealing now with an open circuit... :palm:
Per Hansson:
The meter must be switched to the DCV mode to measure the input impedance.
Here an example of two meters:
--- Code: --- UTE61E: AN8009:
OFF: 25.60M 36.4M
1V: 11.15M 10.982M
10V: 10.13M 10.085M
100V: 10.04M 9.995M
1000V: 10.03M 9.985M
--- End code ---

Please watch below video with sound to hear to buzzer. I pressed on the case to show you that the meter it's alive.

That's quite odd behaviour; normally when you can affect things by for example pressing on the case, it's a bad connection issue. The microprocessor seems to be cycling ranges; the impedance readings on V are what you might see with a constant range cycling. Have you inspected the leaf contacts on the rotary switch?
You need to set your clamp meter to read voltage when you check the resistance/continuity/diode functions.
andyB2022:
The screws are not in the case that's why I've had to press on it, as I open it and put it back very oftenly nowdays (so the LCD makes contact and shows you guys something).
The leaf contacts are in pristine condition, so are the gold plated traces under them (just so you guys understand how much the meter was used it doesn't even have scratches caused by the contacts from many "switches" between different measurements).
