Features MEGGER MIT485/2 Telecom Insulation and Continuity Tester
- Gated access to 500V prevents accidental damage when performing up to 100GΩ insulation tests at this voltage
- Single automatic resistance range: 0.01Ω to 1.0MΩ makes continuity testing quick and easy
- Voltage is stabilised throughout testing
- Input impedance is 10MΩ in order to prevent loading the circuit and reporting low voltages
- Test voltage is indicated throughout testing on the smaller digital readout whilst the measurement detected is indicated on the larger display
- Test range is indicated on the display during selection
- REN value is displayed for the circuit under investigation
- Will indicate Pass or Fail using tick and cross icons
- Rechargeable options are available which can be re-powered using mains or car chargers
- Redesigned case with a back-stand and 6-cell battery and separate fuse access
- Compatible with optional magnetic hanging strap (NOT included)
