The voltage in an electrical circuit is the first parameter that you need to measure to analyse it correctly. Vitrek 4700 Precision High Voltage Meter is one such high voltage testing equipment that is used to measure the voltage in any given circuit with a high level of precision. The equipment is designed ergonomically to make it easy to use. This high voltage testing equipment works on the DSP technology that measures the voltage of AC as well as DC circuits with a high amount of accuracy, resolution as well as repeatability. The device beats the competition by a fair margin due to its portable construction, a higher level of direct and instantaneous voltage measurement as well as sturdy benchtop enclosure.

High Voltage Test Equipment – Description

The 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 HV SmartProbe™

Vitrek’s 4700 precisely measures voltages directly up to 10KV, right out of the box – with no external probes. That’s high enough for most 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, 100KV and 150KV SmartProbes™. The VitrekSmartProbes™ 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 VitrekSmartProbe™ to be used with any 4700 High Voltage Meter. The SmartProbe’s™ proprietary, ultra-low TC attenuator design minimizes self-heating – while its lower capacitance 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

The main aim of the company is to provide consistent results with its high voltage testing equipment for a long period. The places where the device is popularly used by industry leaders include production lines for mass-produced products as well as imaging equipment in hospitals and laboratories.

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. Available G series probes offer extremely high input impedance options for electrostatic voltmeter applications in high voltage testing equipment.

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.

Available ISO 17025 Accredited Calibration

The 4700 and probes come with an ISO 17025 accredited calibration certificate with data at no charge. Vitrek is accredited to ISO 17025 by A2LA. Consider Vitrek at the forefront when it comes to your annual calibrations for the 4700 and probes.
