Insulation testing is a vital part in maintaining and repairing electrical goods.  This testing becomes even more important when working with high voltages.

When performing high insulation measurements the MI2077 Has a wide range of options available for testing with.  This tester can measure up to 5 TΩ (Teraohms) on a timer that can be set between one second and thirty minutes. Also capable of capacitance measurements up to 50 µF and DC test voltages between 250 to 5000V in steps of as little as 50V. The Metrel MI2077 is a versatile and adaptable way to test the insulating properties of any system.

This tester can withstand voltages up to 5500V which is very useful while performing current leakage measurements. While performing these tests a ramped mode can be used to gradually raise the voltage up to a selected value. This will apply electrical pressure to the substance being checked and will show any potential weaknesses. These tests are performed at preset threshold test currents of between 1mA to 1.4mA.

The Metrel MI 2077 is built for safety too with automatic discharge of capacitive loads and a guard terminal to eliminate surface leakage current. Keeping with the very highest safety standards the MI2077 meets the following standards : IEC/EN 61557-2, (EMC) EN 61326 Class B, EN 61010-1 (instruments) and EN 61010-031 (accessories).
