The new Megger MIT 520 Insulation Resistance Tester is available from Macey’s Electrical .
The Insulation Resistance Testers have a large easy to read backlit LCD display making it equally suitable for use in both bright sunlight and poorly lit environments.
Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant.
In addition, the elapsed time of the test is displayed constantly, removing the need for separate timers. Adjustable timers and limit alarms are included.
The Insulation Resistance Tester can test when being powered by the mains or its internal rechargeable battery, a great benefit when site conditions are unknown or long term testing is required.
The controls of the Insulation Resistance Testers are clear and unambiguous and a quick start guide is included in the lid of the instrument removing the need to carry bulky manuals under site conditions.
The Insulation Resistance Tester is fitted with a guard terminal to enhance accuracy. The guard test lead is included as standard with the instrument.
To further enhance the flexibility of the Insulation Resistance Testers both have the facility to set the test voltage in steps from 50 V to the maximum output voltage avoiding the expense of several insulation resistance testers to meet your application needs.
These IR testers are designed to meet high safety standards and the requirements of EN61010.
In addition, the Insulation Resistance Tester measures the voltage at the terminals and if this is above 50 V then the instrument will display the high voltage warning and inhibit testing.
At the end of the test the Insulation Resistance Tester will automatically discharge the energy transferred to the equipment during the test phase.
The MIT520 and MIT1020 are equally suited to routine testing and diagnostic regimes being pre-programmed with IR, PI, DAR, SV and DD profiles.
