Does anyone have any documentation about a Fluke 735C 10.00000 V DC Reference Standard? Thanks Joe

I posted this on the 6th and it appeared. It was answered once and I responded. Now it comes out again. Am I missing something? If anyone has any other information, I would appreciate it. Thanks.

As someone pointed out, these were used internally by Fluke and may not have been commercial products, so there may not be any documentation on the loose. Have you checked to see how closely the 732A docs match what you have? Best regards, Charles

I guess you are not the only one who is busy at work. That could explain the slow answering. And I already told pretty much all I know... The 735 prototypes were some sort of "missing link" between the 731B and the 732A. The project probably started as a "temperature stabilized 731B" and the reference circuitry of the C version was quite close to the commercial 732A. >Do you have any 'specifications' or other documents about it? I think the 735 series was an R&D project rather than a commercial product. Someone who worked for Fluke could have something. >The 'TH' resistance read about 8000 ohms (IIRC) and slowly >came down as the unit 'warmed up'. This AM it is about 3330 ohms. >I'd love to know what the 'normal value' of this is at operating temperature. 3300 ohms => 50 - 55 C oven temperature. The actual value is not important, if the resistance is stable the oven works as it should. >The NiCd pack (of five 'units', side by side, with each 'unit' being >two 1/2 D cells stacked on top of each other) is 12 V 2.2 AH The charger circuitry could be closer to the 731B than the 732A...
