HIGH VOLTAGE PROBES
for Oscilloscopes, Digital Meters & Recorders
HV Probes for Oscilloscopes, Digital
Meters & Recorders
The Ross VMP high voltage probe with it's OSHA safety complying HV
insulated handle accurately measures high voltage with as low as 0.1% DC
and 0.5% AC accuracy, wideband, DC to 1MHz up to as high as 10MHz when
matched with the appropriate meter or oscilloscope. Voltages can be read
at a convenient 1000:1 ratio or 10,000:1 ratio. Other ratios or multiple
ratios also available. Ideal for power supply DC voltage and ripple
measurements, pulse viewing and measurement with waveform display,
measuring or recording device. Ross collapsible insulated handle "Hot
Stick" is supplied according to OSHA recommendations to maintain the
proper clearance between HV and personnel. Insulated 100KV per ft for
protection, the Ross "Hot Stick" handles easily connect to the VMP probe
as well as collapse to fit into an optional protective carrying case.
Hand held probes 5KV PK to 400KV PK and base mounted high accuracy
compensated wideband voltage dividers for both indoor and outdoor use from
5KV to 1,000KV DC or PK AC are available. Also available are base mounted
high voltage precision Voltage Dividers to ±.01% DC and 0.2% 50/60Hz.
Allow 8 weeks for delivery. Specify Power class RMS or Electronic Class DC
or PK AC operate voltage, ratio, length of coaxial output cable,
instrumentation load input resistance and capacitance, DC and/or AC
accuracy and frequency range desired. Complete voltmeters, display
recording and fiber optic transmission systems are available.
VMP Probe Series
The Ross VMP HV probes are designed for hand-held portable
applications with insulated handle, or mounting in a fixed position. The
portable capacitive, resistive, or compensated types are used with digital
multimeters, oscilloscopes, and various types of panel meters. Resistive
types are used primarily for DC and 50 or 60Hz AC or other specific single
frequency sine wave, while the capacitive types are used for wideband and
pulse work. Compensated resistance/capacitance wideband DC to 1MHz (or
more) models are preferred for general use In both the VMP and VD Series.
Standard calibration is centered around 2/3 to 3/4 of
the maximum rating and is matched for 1 megohm, 20 to 50pF or 10 megohms
75-100pF of load input impedance of display or recording device and
optional 3ft(914.4mm), 6ft(1828.8mm), or 15ft(4572.0mm) (please specify
the shortest practicable length) of RG-59 or special Ross Engineering
Corporation coaxial cable. Fiber optic system or 50-75 ohm matching
amplifier/coaxial cable driver is recommended for wide-band transmission
over 20ft(6096.0mm). Any type can be calibrated with best accuracy and
specified stability at specific frequencies, voltages and loads within
their capabilities. Unless rules of shielding and proximity are followed,
VMP series models may not be as accurate as the VD models due to wider
variation in possible proximity of walls, equipment, etc. Other ratios and
matchings are available.
