Digital Insulation Tester (CA-6555)

  • Short-circuit current: 5 mA
  • Large backlit LCD screen with digital display, bargraph and R(t)+u(t), i(t) and i(u) graphs, as well as fixed or adjustable voltage
  • Multiple test modes: voltage ramp and step with “burn-in”, “early break” and “I limit” modes
  • 3 filters to optimize measurement stability
  • Automatic filter for measurements in strong electromagnetic fields
