Hi guys.
I managed to buy a Fluke 8810A for £1, knowing that it wasn't working. The selection switches were broken bar one, and they were also jammed. Also the meter didn't seem to measure properly.
I thought that at worst, it had some 7 segment displays which I could salvage, as well as a transformers, etc...
But I'd like to fix it.
I managed to fix the jammed switch by pulling out a piece of metal which did nothing other than prevent the switches from ascending into place. I'm making up a couple of new switch levers at school, so those parts are sorted.
However, I've tried calibrating, but it seems impossible. I've read the manual (http://www.ko4bb.com/Manuals/Fluke/Fluke_8810A_Digital_Multimeter_Instructrion_Manual.pdf), but I cannot get it to settle. The decimal point moves around, and the variable resistor which is used to calibrate does nothing. The variable resistor does work, I've checked it with a multimeter.
YouTube video here with all the information.
