Default Re: AVO Electronic Test Meter - getting the case off.

On early models AVO used different size on the hole in the collar, the side with the beveled hole is usually the larger hole (only by some tenths of a millimeter) and it is easier to push the pin out from the other end then (the side with the smaller hole) - later models have equal sized holes.

You can use a polygrip plier to compress and also to rotate the pin if it has seized up.

I usually put a tube, some 10-15 mm long, that fit on the pin on the side that I want it to be pushed out at and then use the polygrip plier on this tube and the pin to push it out into the tube far enough so that I can grip it and pull it out while rotating it slightly.
