High Voltage Meter Systems Most Ross Meters are supplied as systems consisting of one of the basic meters matched to the VMP series voltage probes or VM series voltage dividers. The VMP series hand held probes extend the voltage measuring capabilities safely to 400,000 volts. The base mounted VD series dividers can extend capabilities, safely, to as high as 1,000,000 volts. Most of the systems provide outputs to drive oscilloscopes, recorders etc. Systems utilizing the VMD2A can use it's amplifier output to drive 50 ohm shielded cable and instrumentation at frequencies from DC to 10MHz with useful accuracy. Meter systems are also available, featuring a portable combination voltmeter and oscilloscope to provide voltage waveforms as well as voltage levels.
