Apparently, ohms/volt applies to the full-scale reading for a given range. For a 1000 ohms/volt meter with a 0 to 100 volt range, the meter presents 1000 * 100 ohms (100k ohms) when the meter is reading full scale. I was trying to interpolate the ohms that's presented to the circuit from the

I'm in the process of refurbishing my Hickok 752A and I have a general question regarding the calibration procedures. All voltage measurements are supposed to be taken with a 1000 ohm/volt meter and I don't have a meter like that. >From what I understand, if one measures, for example, 150VDC with
