I have a Monarch MT-222 analog multimeter. Mind you - this is a genuine Monarch MT-222, not some cheap imitation. Two jewels! Anyway, over the years I've had to rework the DUT end of the leads several times, but would really like to just get new leads. The problem is that the meter ends of the leads are very small pins. They are about 1/16 inch, a little less than 2mm. Everything I see online is either shrouded, or banana plug, and much bigger. Does anyone know where I might find the right leads, and what would be the correct term to search for? This meter dates back at least to the 70's, and is no longer my primary analog meter. But I would like to restore it to a useful condition, and would rather avoid splicing if I can. The AA says best if used before 2002, so I probably will replace that, although at 1.48V it's just broken in. But otherwise I just need to get leads that work.
Probemaster has these with 0.080" pins. Does that work?

No-load voltage? Then it’s already going bad. Given the age, leakage is a likely outcome, and given how cheap AA batteries are, just replace them.
I think the Probemaster leads would work. But at $22 plus shipping, I could just buy a new meter as good as this one. So I guess I'll rework the ones I've got, and try to implement some better strain relief.
As for the battery, I think I will use this meter for current and voltage, mainly current, so it won't need a battery at all.

Which will come with awful probes that are worth exactly what you paid for them. Probe Master probes are worth every cent, they’re just lovely to use.
Of course, Probe Master isn’t the only company that makes pin style multimeter probes. Or you could get whatever probes you like and replace the banana plugs with pin plugs. Or keep the banana plugs and use an adapter. You could also modify the meter to replace the pin sockets with banana jacks. There are so many options.

How much is your time worth? $22 is not much money these days, the McDonalds near me is hiring starting at $17/hr. Seems fairly reasonable for a set of good quality test leads.
