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 
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 
- 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 choo      r 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-    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?
