DescriptionMegger MIT481/2 Telecommunications Insulation TesterProduct Description:The Megger MIT481/2 Insulation Tester, part of the advanced Megger 480/2 series, is designed specifically for telecommunications and cable-testing applications. It offers high accuracy and efficiency, featuring feedback-controlled insulation test voltages that are accurate to within 2%. This ensures reliable testing while preventing damage due to over-voltage conditions. The MIT481/2 allows for a convenient three-terminal connection, enabling A, B, and E leads to be connected simultaneously, with the ability to select them through an intuitive on-screen interface. This eliminates the need for time-consuming cable swaps and provides a more efficient testing experience.The tester supports insulation testing with selectable test voltages of 50V, 100V, 250V, and 500V, and can measure insulation resistance up to 100GΩ. For added simplicity, the device provides a pass/fail indication on-screen, and both the test voltage and insulation resistance value are displayed. The dynamic measurement readings are indicated through an ‘analogue’ arc. To enhance safety, the tester automatically shuts down after a specified period, detects over-voltage conditions, and inhibits testing when dangerous voltage levels are present. Additionally, an audible buzzer will alert the user if insulation resistance exceeds a user-set limit.For continuity testing, the MIT481/2 provides two current options (200mA and 20mA) and features an automatic range from 0.01Ω to 1MΩ. It also includes NULL lead resistance compensation to improve accuracy. The tester displays differential measurements between two consecutive continuity tests and provides true RMS voltage measurement capabilities, along with frequency and capacitance measurement.The Megger MIT481/2 has a weatherproof, over-moulded design that meets the IP54 standard, making it suitable for use in demanding environments. The redesigned case, back-stand, and separate fuse access in the battery compartment further enhance its durability and user-friendly design.Key Features:Designed for telecommunications and cable testing, with insulation testing up to 500V and 100GΩ resistanceContinuity testing with automatic range from 0.01Ω to 1MΩ and two current options (200mA and 20mA)True RMS voltage measurement from 10mV to 600V AC/DC, along with frequency and capacitance measurementThree-wire connection (A, B, E) for simplified testing with no need for cable swapsWeatherproof to IP54 standard, with over-moulded casing for increased durability and safetyTest voltage accuracy within 2% to prevent over-voltage damageDigital display combined with an analogue arc for dynamic measurement indicationAuto-testing function for enhanced convenience and efficiencyWhat’s Included:Megger MIT481/2 Insulation TesterMegger MIT481/2 Insulation Tester Owner’s Information CDRed and Black silicone test leads with probes and clipsSP5 switched probe (not available with MIT400/2)6 x AA alkaline batteriesHard carry case for secure storage and portability
