Re: 2401C Integrating Digital Voltmeter and 2410B AC - Ohms Converter


 

I have also a set in the repair queue.? My 2401C sounds to be a bit older than yours, Terry, as it's the Dymec-labeled version, s/n 622-01154.? The 2410B is 644-01052, and despite having a lower serial number than yours, mine has an HP-labeled front panel.

I'll need to fabricate some boards to integrate them, though, as they weren't a set and the 2401C is not equipped with the boards needed to let it talk to the 2410B.

Gotta love a full rack width, 20+ inch deep, 13-1/2" tall nearly 100lb stack of gear that will measure DC and AC voltage, and resistance.? One of these years, in my spare time (so called because I have so little of it...)? Cool old boat anchors - it's nice to know others are keeping them alive, too.

Some photos of the 2401C are at?

Who here, runs these find beasts?

My HP 2401C Integrating Digital Voltmeter (SN 811-02807 opt 21,31,146) and HP 2410B AC - Ohms Converter Dymec (SN 644-01126) are about to be restored, interconnected and calibrated.

They don't appear to have been mentioned in this forum before, but I'm betting someone out there is also keeping these in working order.

Incidentally, they are both in pristine condition, remarkable for their age, and the?2410B has a asset sticker from a previous owner, the NASA? Goddard Space Flight Center, which will be left on the instrument.?

Kind regards,
Terry
