Testing With The Megger MIT220

Continuity Testing

  • Automatic continuity testing is performed at 200 mA to ensure compliance with international requirements.
  • Autostart feature - no need to press the test button to begin the test (both hands can be used to hold the test lead probes).
  • All instruments will measure up to 100 Ω on continuity, with 0-10 Ω using 200 mA so meeting international electrical testing requirements.
  • Lead null is possible up to 9.99 Ω of test lead resistance, providing the ability to null fused, extended or standard test leads.

Continuity Buzzer

  • A buzzer provides a means of rapid cable testing and circuit continuity identification, with voltage protection should you accidentally touch a live circuit.
  • The buzzer operates at a 2 Ω threshold.


  • Every Megger instrument is designed with safety as its primary objective.
  • There are in-built safety checks to warn of inadvertent connection to a hazardous live supply on all ranges.
  • All instruments meet or exceed the requirements of safety directive IEC 61010 and EN 61557 for insulation and continuity testing.

Default Volt Meter

  • A built-in voltmeter is automatically activated and displays the system voltage when the instrument is connected to a circuit with an a.c. or d.c. voltage greater than 25 V.

Test Inhibit

  • Circuits in excess of 25 V will generate a voltage warning.
  • The instrument will inhibit testing on circuits over 50 V on both continuity and insulation test ranges, protecting the operator and the instrument from injury or damage.
