HV MULTIMETERS
for High Voltage Use
Basic Meters
The sturdy, compact and portable
Ross VMD and VMDP series voltmeter are available with 3 1/2, 4 1/2 or 5
1/2 digit readouts. Some units feature accuracies as good as 0.01% on DC
and 0.1% on AC measurements. Meter with frequency responses from DC to
10MHz are available. The capability to follow voltage peaks from DC to
over 5MHz or capture and store peak pulses as short as 200 nanoseconds is
built into the revolutionary new VMD2A Voltmeter. These basic stand alone
meters can measure voltages from 10 microvolts to 1000 volts, and to
1,000,000V with Ross voltage dividers.
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.
High Margins of Safety
The models utilizing the VMP series
probes or VM series voltage dividers are carefully designed to provide
utmost safety when measuring high voltage, whether it be low power
electronic systems, high voltage industrial equipment or high voltage
power lines. Extremely high OSHA and power class safety factors are
provided. These high voltage, high power probes have impulse ratings
providing safety factors well in excess of two times their rated voltages.
Other Ross Products
Wideband Fiber Optic transmission
systems are also available to transmit the outputs of voltage dividers
over non-conductive fiber optic cables up to 1 kilometer to provide the
ultimate in operator, safety and elimination of electrical pick-up and
ground currents. A wide range of high voltage power control products are
also available, such as the following: High voltage relays, high current
switches, vacuum contactors, spark gaps, high power control and step-start
systems, high voltage safety devices.
