The new Vitrek 4700 Precision High Voltage Meter offers the highest level of measurement accuracy, yet is surprisingly easy to use. Vitrek has harnessed DSP technology to provide outstanding AC &DC voltage accuracy, stability and resolution. Performance that rivals traditional HV reference dividers, yet unlike the delicate HV divider, the 4700 provides instant, direct, high voltage measurements in a highly portable, compact and rugged bench top enclosure. The 4700's large, high resolution, color, touch graphic display simultaneously shows the AC and DC content of the voltage being measured and can plot readings from a few seconds to several days. |

Direct Measurement or SmartProbe™ - You Make the Call
Vitrek's 4700 precisely measures voltages directly up to 15KV, right out of the box - with no external probes. That's high enough for 90% of the HV sources out there, however, should you care to expand your high voltage measurement range - just add one or more of the available 35KV, 70KV and 100KV SmartProbes™. The Vitrek SmartProbes™ each store their own calibration data which is down loaded when they are plugged in to the 4700 - this results in high accuracy, calibrated readings and allows any Vitrek SmartProbe™ to be used with any 4700 HV Meter. The SmartProbe's™ proprietary, ultra low TC attenuator design eliminates voltage coefficient adders - while its reduced capacitive construction technology enhances AC performance. In addition to the direct input terminal the 4700 has two probe inputs - use one probe to extend your measurement range or use two probes for making high voltage differential measurements.

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. To insure the best possible measurement accuracy, the 4700 makes over 40,000 reading per second which are then filtered, sub-sampled, scaled and offset corrected - all with "error free" mathematic methodology. The True RMS AC readings are as true as they come, while the DC measurements offer rocket fast settling with rock solid stability. In addition to this, the 4700 provides VLF AC readings down to 0.01 Hz, as well as, peak to peak, crest factor and fundamental frequency measurement.
High Voltage Test Automation
Automate your HV test requirement with the 4700's built-in Ethernet port, high speed serial communication port or available GPIB. The 4700 is fully programmable - so you can select your measurement mode and bandwidth, then take readings as often as desired. The 4700 also comes standard with a USB printer port, to capture readings and get hardcopy printouts of HV plots - so you can document the sag or overshoot in a typical hipot test.
