The Megger MIT310 Insulation and Continuity Tester is designed specifically to meet the needs of today's electrical contractors: it is not only durable and easy to use, but also incorporates a comprehensive set of features designed to ensure operator safety, even under conditions of accidental misuse. Large 20mm high characters provide a very clear readout, which is combined with an analog arc for the feel of an analog instrument, with a true analog response.

The MIT310 Tester offers automatic discharge of the circuit after testing, audible and visual warning if the test probes are applied to a live circuit, and a test inhibit feature which operates automatically under live circuit conditions. The units also conform fully to IEC 61010-1 for use in Category III 600V applications, and provides all of the facilities needed to meet insulation testing requirements relating to the current edition of the IEE Wiring Regulations.

The MIT310 insulation tester features rugged construction, with an impact-resistant rubber-overmoulded case, and innovative circuitry which guarantees high accuracy combined with stability of calibration.

The MIT310 provides indication of insulation resistance up to 999Mohms, 200mA continuity testing, a fast-reacting continuity buzzer, and facilities for nulling the resistance of the test leads. The unit allows testing at 250V, 500V and 1000V. The MIT310 Insulation and Continuity Tester also offers a default voltmeter function.

The MIT310 tester incorporates a dual solid-state display, which simultaneously shows the test results numerically, and in the form of a moving-arc bar graph that accurately simulates the operation of an analogue meter.

The MIT310 tester comes complete with a full calibration certificate.
