Precision Standards AC-DC Differential Voltmeter 360A - manual

• Precision Standards AC-DC Differential Voltmeter 360A - manual
  Posted by calin on 18 Apr, 2024 03:58
• I recently got an Precision Standards  Corporation AC-DC Differential Voltmeter, model 360A which I literally got it just because I've put a low ball offer and I got it for the price of a coffee.
  
  Now I kind of want to restore the thing but I cannot find the manual anywhere. Does anyone have by any chance a hint from where I can find the manual ?
  Either my Google fu is very low these days .. or really there is nothing I can find on the interwebs.
  
  Here is a picture of the thing .. maybe it helps to identify a manual

• Does it seem to work?  I wonder if you can get by without the manual.

  Give it a visual inspection inside before trying it, to make sure there are no burnt parts, or any of those leaking wet tantalum capacitors that were commonly used in some 60s & 70s test gear.

• Does look like working / turning on somewhat without releasing any magic smoke. But that's about it, the dial indicator just sticks to the max when I try to measure anything  and that is it.
  I am a tad weary sticking my fingers too much in, when this thing is running, as it does produces internally some high tensions especially on the higher ranges.
  At worst I can gather some really nice precision resistors from the innards and end up with a nice project box if nothing better comes out of it
