HV Standards Lab in a Box

When it comes to making precise high voltage measurements, there is nothing
faster or easier than the Vitrek 4600B Series.  With its unrivaled accuracy and
direct reading capability, the 4600B Series sets the performance standard for
precision high voltage measurements.  For quick and accurate calibration of
Hipot testers (dielectric strength testers) and other high voltage sources, the
4600B Series can’t be beat.  Whether you are making DC or AC high voltage
measurements, the 4600B Series is uniquely equipped for the job.  For rock solid
DC performance, the 4600B Series' multi-slope integrating analog to digital
converter provides fast, stable readings even in the presence of noise and
ripple.  For accurate AC measurement with either sine wave or distorted
waveforms all of the 4600B Series units feature the latest in true RMS
measurement conversion technology.  The 4600B Series is equipped with two
voltage scales to cover a broader span of voltages and select the ideal range
for optimum resolution and accuracy.


Test Automation with Opto-Isolated Serial Communication

Automate your HV measurement task using the high speed RS232 comm port or
available USB. With the new fully programmable 4600B series, you can set mode
and range and take readings all automatically.  Plus the B series offers new
features like, Maximum reading mode - which can accurately capture the peak
integrated reading on a 1 second hipot test. Addition features include - minimum
reading mode, display hold and extended filtering.

Superior Performance by Design

Measurement integrity is our bottom line – whether you are on a production
line manufacturing high voltage medical imaging equipment, in a national
laboratory conducting ground breaking research or in the cal lab certifying test
equipment, it is essential to choose your tools carefully; take the Vitrek 4600B
HV DVMs, for instance.  This rugged compact instrument is equally at home in the
lab or in the field.  Underneath its attractive, high impact, injection molded
enclosure, lies a steel Faraday cage, a guarded compartment to discriminate
against the introduction of uncertainties due to stray capacitance and EMFs that
are often present in high voltage applications.

The modular construction of the 4600B Series probe features a removable probe
tip, which can be replaced with a variety of available HV leads to provide the
ideal connection for your application.  The high impedance attenuator design of
the 4600B Series balances offsetting power and voltage coefficients to deliver
laboratory grade performance in a bench­-top package.  The 4600B Series
attenuator also features a patented non-inductive design to minimize field
effects and provide enhanced AC performance.  For people on the go – the 4600B
Series is available with a standard carrying handle and an optional battery
pack.  For systems applications the 4600B Series is available with rack mount
adaptor and rear panel inputs.

The Vitrek 4600B Series is not only built tough, it is built to last – and it
is backed by our Extended Three Year Warranty.  Designed and manufactured right
here in the USA, the 4600B Series is backed by the best customer service team in
the northern hemisphere.  Isn’t it about time to put Vitrek’s legendary
reputation for quality and reliability to work for your team?

Dual Probe Option

A standard 4600B measures a HV source to common (within 500V of ground).  For
HV phase to phase AC or differential DC measurement (i.e. +10KV to -10KV) order
the DPD option.

The Vitrek 4600B Series is not only built tough, it is built
to last – and it is backed by our Extended Three Year Warranty. Designed and
manufactured right here in the USA, the 4600B Series is supported by the best
customer service team in the industry. Isn’t it about time to put Vitrek’s
legendary reputation for quality and reliability to work for you?  *
