Re: Ferrograph 4A: Restoration advice needed
Ohms per volt is range related, eg: if the meter is 20k per volt on DC and it's switched to the 250 volt range the resistance across the meter probes will be 5 meg ohms (20,000*250) on the 100 voltage range it would be 2 meg ohms (20,000*100) and so on etc. The loading effect on the voltage to be measured will vary according to the voltages source impedance, think potential divider.
