Very high input impedance high voltage meter???
I have an HP200CD that needs some loving care. The manual says to measure
the difference in the voltage between two different points in the circuit -- it shouldn't be all that much but the voltages between these points and ground is in the hundreds of volts range. The manual also says that I should be using a meter with 220M ohm or greater input impedance to make the voltage measurements. Any suggestions where such a beast could be bought/rented/stolen?
