I just unpacked the HP 331A that I bought for$19.99.
It's a newer unit that uses the
common IEC C13 power cord instead of the hard to find oval type. It's in
a brown case, with rack ears.
Have you tried powering it up yet? Looks to be in fairly decent
physical shape.
Yes, and other than a couple dirty switches, it works great There are a couple minor scratches in the covers, and a little reside from cal tags. The ironic thing was I paid one cent less that for the one that got destroyed, and I bought it about 25 years ago. That was military surplus, and someone had spray painted the covers, rather than remove the old labels. I'm going to see how bad it is inside, and if it's salvageable, I'll see about converting it to a digital display. That will limit the number of useful ranges, but the 4 or 5 digit display will more than make up for that. BTW, I ask the current rating for the meter in the 331/332/333/334 in my first post to the group and got no answer. I can see a 1 mA rating, well below the normal viewing area.
