Here is the complete manual for the 47-1230, but it is in DjVu format and you will have to download a free viewer to see it.

A 20000 ohms per volt meter has a lower input resistance on the lower ranges which will result in lower voltage readings than a DVM like a Fluke. So your measurements with the DVM may result in slightly higher voltage readings than those obtained from the schematic. Don't take exact voltage readings too seriously as they can be subject to significant variations due to component tolerances.
