content: I am looking for any technical information about the 700A-04 Standard Cell Enclosure. It uses 4 off Muirhead 402C/P Standard cells. There is some information available on the actual cells used bit I have drawn a blank on information about the whole instrument.Manufactured by Elmeasco Instruments based in Sydney & supplied in the UK by Walton Electronics Ltd. in Basildon.I bought this in December to save it from the scrap man & was pleasantly surprised to find that the cells were still good (pretty closely matched) & when it settled down, & at the operating temperature, evrything looked great. Only notable detail was all 4 cells read somewhat higher that the original values recorded when checked with my HP 3458A -- back from calibration by Keysight in early December.The battery was last changed in June 2007 & needed replacement. There is a label on it referring to the UK National Physical Laboratory so it may have been there for at least some of the time.Any thoughts or information gratefully received. I planned to keep it as an exhibit but as it is still working this seems inappropriate.Phil

content: I have two of these enclosures - one from a place I used to work, with history and complete OEM manual, the other a dumpster save. The manual is printed on VERY thick paper, spiral bound, so scanning will be a bit of a pain (won’t go through the feeder) but I am willing to have a try. I presume that you have tried all the usual sources (bama, KO44, etc)?

content: Hi,I have tried all the usual places without success. I appreciate your kind offer to try & scan the manual. I am guessing that most of it is useful but not essential reading. I am really interested in the original specifications plus any circuit diagrams & repair information. Would this be easier & quicker to scan than the full manual?I am also interested in the history of it. With the rather nice teak case it looks like something from the 1960s but this guess may be wildly wrong. For now mine is sitting next to my Datron 4910 until I decide what to do with it. Far too nice for scrap especially as it actually seems to work rather well.Thanks for any information you can offer.Phil

content: Phil,I have had some success with my brand new Brother mfc and its associated app - one nice pdf, clear as a bell. Not sure what is the best way to get it to you - should I post it to Ko4bb or bama or somewhere, or direct pm you? I don't have much experience in this aspect of it - Maybe you or others others can advise. (file is 3.8MB).I need to point out that the manual, although it contains a couple of versions of the schematics, nevertheless does not accurately reflect the exact configuration of either of my units, but was certainly close enough to allow me to fault find and repair.Roman

content: Hi Overspeed,Thank for the link. I had found this offer but wanted the original manufacturers information rather than something from a advert.Roman Oh has kindly uploaded the information to K04BB's site so now I will be able to find out what the specification was meant to be.Thanks to everyone who offered help. I really do appreciate how good the people on this forum are.Phil
