Re: AVO Electronic Test Meter - getting the case off.
If the roll pin size is 'correct' for the hole it occupies, it may be possible to compress both ends with small self-grip wrenches to defeat it's seizure.. ie closing the roll pin to a marginally smaller diam.
IF (repeat if!) it's feasible to use some heat, wd40 can be applied afterwards, as the cooling joint draws the lubricant in to where it's needed.
