  • Description

    Megger MJ10 Analogue Insulation & Continuity Tester

    The Megger MJ10 Multi-voltage Insulation & Continuity Tester is a modern, portable, self-contained instrument designed to give rapid and accurate measurements. The Megger MJ10 Analogue Insulation Tester has four DC insulation testing voltages of 100V, 250V, 500V and 1000V (1kV), with a single insulation resistance range of up to 2000MΩ. Continuity is measured, with either polarity, on a single 0-4Ω range. Power for the MJ10 is derived from a low voltage, hand-cranked generator which is easy to turn even under full load conditions. The low voltage generator is connected to an electronic inverter to provide a very stable test voltage. The variations in the generator cranking speed do not affect the accuracy of measurements. The test voltage is maintained at its rated value as low as 1MΩ at 1000V or 0.5MΩ at 500V.The Megger MJ10 tester has been designed for convenience and ease-of-use when testing complex or larger electrical installations and commissioning, servicing or maintaining electrical equipment. The MJ 10 is ideal for the safe testing of motors, generators, cables, switchgear, transformers, distribution networks, industrial and domestic installations, components and appliances. The range of insulation test voltages available means it can be used for a variety of applications. Test leads with fused prods are an option recommended for use when checking that equipment has been isolated from the supply (by performing a voltage test), especially in high energy situations.

    Megger MJ10 Analogue Insulation & Continuity Tester Features:

    • Standard DC test voltages of 100V, 250V, 500V and 1000V
    • Powered by a low voltage, hand-cranked generator.
    • Guard terminal
    • Continuity range up to 2000MΩ with polarity reversal
    • Automatic capacitve circuit discharge facility
    • Voltage range for indicating an energised circuit

    As a safety feature, the AC voltage range becomes effective as soon as the device is connected to the circuit under test. A warning is given if the circuit is not deenergized before the instrument is operated. This range also acts as a monitor for the automatic discharge facility so that after equipment having capacitance has been tested, an indication can be given that the voltage has discharged to a safe level for removing the test leads. The MJ10 has a guard terminal to divert leakage current away from the measuring circuit so that readings are left unaffected. The continuity measuring function of the MJ10 has the facility for reversing the polarity of the test current without altering the test leads. The operator may then eliminate the effects of standing EMFs etc by averaging the measurements made with both polarities. This is a robust, lightweight device that is built into a strong polycarbonate case. All readings are given directly on an analogue meter with a white on black scale and orange ‘dayglow’ pointer. The ranges are selected by a rotary switch and a ‘Test’ button is pressed while simultaneously turning the generator handle to execute a test. The test leads supplied have right angled connectors and, when fitted to the instrument’s recessed terminals, the carrying handle folds down over them. These features help to ensure that the leads are not accidentally pulled out of the terminals during a test.
