Default Solartron/Schlumberger 7065 Voltmeter Resistances Section

Dear All!

I own an old Solatron 7065 Voltmeter. Recently I noticed that the resistance measurment works not correctly. After some testing I found that the current generator for the resistance measurement provides not the right reference current. I downloaded the operation and service manual from BAMA but unfortunately the pages for resistance measurement especially the schematic diagram are missing. All other pdf files I found in the internet were also incomplete, it seems that they came all from the same origin.

Now my question is does anybody have a service manual for the 7065 with the part of the resistance measurement (page 4.2.12 to 4.2.14, especially the diagram 2.5)?

Thank very much and

Best regards

Solartron 7065 Resistance circuit. I will scan the pages 4.2.12 to 4.2.14 which you want over the weekend. While I am struggling with the A3 sheets, are you missing other bits of the manual, as I will see if I can do them at the same time. Send me a Private Message. WME-Bill m0wpn

Solartron 6065 voltmeter. Manual extracts.
for "Joerg Niese". Circuit Diag 2.5 of resistance standard current generator pages 4-2-12 to 4-2-14.
for "tb10 flyer", following his PM. Introduction, pages 1.1.3 to 1.1.4.
All as requested. Both are about 350kB, so I'll attach here.
I have scanned all the Specification and introduction, for the 7055 & 7065 microprocessor voltmeters, and all the circuit diagrams for the 7065. It comes to nearly 7Mb. I haven't scanned the whole manual yet, a slow job. If anyone wants all the circuit diagrams, I'll do a CD. It really is too large to send by email.
I have watermarked everything, as I freely provided a rare manual once to someone, which I then saw he was selling on the web. No quite the spirit of this site. WME-Bill m0wpn

Thank you for the pdf-files, WME bill!
That's exactly what I need now. In the next days I will start with the repair work.

Thanks a lot and best regards
