content: HiJust in case you missed it - I have been posting to loads of threads about my score- picked this baby up for £60The only other tear down I have found is here :http://www.radiomuseum.org/r/schlumberg_solartron_system_voltmeter_7060.htmlThere does not seem to be a tear down of this unit here so here is mine :(Also how do I use the insert image instead of the attachments ?)

content: It keeps surprising why there are so much electronics in a precision volt meter.The handheld digital multimeters only contain one chip. While they don't reach the same precision, they are pretty accurate anyhow. So for just 2 digits more, you need so much more electronics?

content: Forgot to mention, I had a good look round the analogue board looking the the voltage reference but could not find anything that looked like a voltage reference. The one transistor device that is socketd turned out to be some op-amp.Lots of high quality componentsI was not prepared to take off the AC RMS boardMaybe I will open it up again and try and work out which device is the ADC, the system volt meter seems to have the ability to take rapid readings, far faster than most multimeters.Does anyone have the user manusl please?I see that now one has the service manual online.

content: nice score!, although I am not familiar with this model or have seen the service manual but my guess is that red diode.
