Re: [volt-nuts] Fluke 735C - Information Needed
Same color scheme on the batteries in the 5315A.

And, the cylindrical sealed LEAD acid cells were also originally commercialized by GE. They later spun off that division to became GATES. I had an old SOLA UPS that was made in the mid 1960's that was full of GE SLA's... The color scheme of the cells was exactly the same as the later GATES cells. (Black bottom, white top with red trim...) and I had an old Sulzer 2.5A double oven oscillator that was full of the GE Nicads from about 1960. GE was big in battery research in the late 50's, early 60's. I don't recall the exact order, but there is a big connection between GE, Gould, and GATES batteries. ... both Nicads and SLA's. -Chuck Harris J. L.

Re: [volt-nuts] Fluke 735C - Information Needed
Will, Thanks for the info. I'll download the 732A manual and see how it compares. It is quite 'the beast'. I plugged it in, connected it to my (recently Fluke calibrated) Fluke 8846A and it read 10.0 VDC. This AM it read 10.7 VDC 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. I need to replace the NiCd's and 'clean up' some corrosion on the battery charger board but it looks like it will be an interesting addition. It has a 'sticker' relating calibration in 1982 by 'Primary Standards Lab' with a 're-cal' date 3 months later. So, that would fit as a 'transfer standard'. I'll have to get it 'back in shape', allow it to stabilize for a couple of weeks then see what it is on my 3458A. Do you have any 'specifications' or other documents about it? Thanks again.

As far as I know it was used for DC transfer experiments from the Fluke primary lab to their other calibration sites. 2013/9/7, J. L.
