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
  • Based on Vitrek's proven DSP technology
  • Can directly control up to four 64 channel HV scanners, right out of the box
  • Has a unique combination of performance features - multi dwell functionality, high speed testing, pico-amp leakage measurement, continuously variable IR test voltage

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)
