The MT500 is a rugged, compact and easy to use Insulation and Continuity Tester. The instrument offers three insulation test ranges: 250V, 500V and 1000V, a 3Ω continuity range and a 500Ω resistance range. This meter is not only equipped with a “Live Circuit Warning” but also displays the actual AC voltage measurements of the mains supply. The scale has a backlight which is ideal when working in dimly lit environment.
