Quoted from Zitt:...
Apparently these multimeters were available as a kit build back in the day....
Probes are long since gone but it appears they may be available on ebay.
What is really scary is this meter and most like it have NO FUSES. :S
I built the kit version waaaay back when, still use it as my "upstairs" meter (when I'm too lazy to go downstairs for a DMM)
They had "fuses"... kinda...
