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... _______________________________________________ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
