atkelar | HP-3476B Cleanup @atkelar | Uploaded May 2024 | Updated October 2024, 59 minutes ago.
Now, what do we have here? The 3476B is a portable DMM from the mid 1970s, so about the same age as myself! It does volts, amps and ohms; the former two in AC and DC. So nothing too spectacular by today's standard. But: digital! With a nifty display! Not Nixies, but the next best thing!
The device was offered as complete; but just how complete it was took me by surprise. It arrived with the carry bag, complete test lead set and owner's manual even. Wow. What a score! The only thing that's missing was the battery pack, and that might have been for the better too!
