Insulation tester designed to test the quality of insulation using 5000V test voltages. It is ideal for testing large motors, generators, transformers and cables. Performs voltage, insulation, and capacitance measurements.

This portable instrument is housed in a rugged field case and operates on either battery or line power that performs voltage, insulation, and capacitance measurements. This instrument contributes to the safety of electrical installations and equipment.

Displays the test voltage, insulation resistance and the leakage current during the test. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test.

Designed with the highest level of built-in safety features. This meter incorporates test inhibit capabilities which will not allow test voltages to be generated if a live sample is detected. The test terminals are recessed to ensure operating safety.
