Vitrek 981i – 6.5KV Teraohmmeter / Insulation Resistance Tester

Vitrek 981i – 6.5KV Teraohmmeter / Insulation Resistance Tester

• 98x series teraohmmeter / insulation resistance tester
• 6.5 KV DC output voltage
• Meets today’s demanding requirements for higher voltage IR testing
• Ideal for higher voltage IR requirements, such as electric vehicle systems and higher voltage solar arrays

The new 981i and 983i Teraohmmeters are designed to tackle the toughest High Resistance measurement applications. Demanding applications that most other IR testers won’t measure up to. So when it’s time to test higher voltage IR values like today’s electric vehicle systems and higher voltage solar arrays – look to Vitrek to deliver the IR tester you need for your production line.

Built upon the same DSP technology that has established Vitrek as a leader in hipot test systems, the 98xi devices feature a unique combination of performance features including:

• Multi-dwell Functionality (multiple steps without having to return to zero between steps)
• High-speed Testing (with dwell times as low as 100 ms)
• Pico-Amp Leakage Measurement (with stable and precise 50 Teraohm IR readings)
• Continuously Variable IR Test Voltage (adjustable over the full output range of the instrument)
• Multi-mode IR (three test modes – end on time, end on pass, end on fail)
• Capacitance Test Modes (critical for solar panels, cable harnesses and other capacitive loads)

What sets the Vitrek 98x Series IR testers apart from the others?

For starters, these units are based on Vitrek’s proven DSP technology – so they have the ability to work into capacitive loads where most others do not. And when it comes to output voltage range, Vitrek delivers – with up to 6.5 KVDC for the 981i and up to 11KV with the 983i.

Need to measure IR on a Multi-Conductor Cable Harness?

The 981i and 983i have the ability to directly control up to four 64 channel HV scanners, right out of the box. That is up to 256 test points and using a PC with Vitrek’s Q-Test software you can expand the count up to 1020 test points. The HV Switching System of choice is the Vitrek 964i, which can hold eight 8-channel switching cards – available in 7, 10 and 15KV ratings.

In a never ending race for higher efficiency, electric vehicles and solar panel arrays are now operating at 2.5KV. This is no place for a 1KV tester, it’s time to step up to a 98x!
