        Major Tech MT587 | Diagnostic Insulation Tester 15kV | Metal Case

        The Major Tech MT587 is a high-performance 15kV diagnostic insulation tester designed for professional electricians. This microprocessor-controlled device features a 4-bit large backlit display and provides precise measurements of insulation resistance up to 50TΩ.

        With test voltages ranging from 500V to 15kV and a short circuit current output of up to 6mA, the MT587 is ideal for testing insulation on rotating machines, transformers, cables, high-voltage generators, electric circuits, and surge arresters.

        It includes advanced functions like Dielectric Absorption Ratio (DAR) and Polarization Index (PI) indication, auto-ranging, adjustable test times, and data storage for up to 500 recordings. The robust metal case ensures durability for extended field use, and the device is powered by 12.6V rechargeable Lithium batteries.

        Diagnostic Insulation Tester Features:

        • Wide Test Voltage Range: Insulation test voltages from 500V to 15kV, with increments of 50V up to 10kV and 500V increments thereafter.
        • High Resistance Measurement: Measures insulation resistance up to 50TΩ.
        • Advanced Functions: Includes DAR and PI indications, auto-ranging, and adjustable test times.
        • Large Backlit Display: 4-bit backlit display for clear and easy reading.
        • Data Storage: Saves up to 500 recordings, which can be recalled and displayed.
        • Safety and Convenience: Automatically discharges the circuit after testing, auto power off, and alarm settings for measured values.
        • Versatile Measurement: Measures up to 750V AC and 1000V DC, and capacitance up to 50µF.
        • Robust Design: Housed in a durable metal case for extended field use, powered by 12.6V rechargeable Lithium batteries.
        • PC Connectivity: Data transfer to PC via optical USB and supplied software.

        MT587 FAQ:

        Q: What voltage range does the Major Tech MT587 cover?
        A: It covers insulation test voltages from 500V to 15kV, with increments of 50V up to 10kV and 500V increments thereafter.

        Q: What is the maximum insulation resistance the MT587 can measure?
        A: The MT587 can measure insulation resistance up to 50TΩ.

        Q: Can the MT587 store test results?
        A: Yes, it can save up to 500 test measurement results in its memory.

        Q: Is the MT587 suitable for field use?
        A: Yes, it is housed in a robust metal case for extended field use and powered by 12.6V rechargeable Lithium batteries, with data transferable to a PC via optical USB.

        Warranty Method: Return to Sparky Direct

        All Major Tech Meters sold through Sparky Direct are covered by the manufacturer’s warranty. If you believe your meter is faulty or defective, you may request an assessment under this warranty policy.

        How to Lodge a Warranty Claim

        To initiate a warranty claim:

        1. Return to Sparky Direct
          Ship the meter back to Sparky Direct along with:

          • A copy of your proof of purchase
          • A brief description of the issue
          • Your contact details

          Please ensure the unit is securely packaged to prevent damage in transit.

        2. Forwarded for Assessment
          Upon receiving your meter, we will forward it to Major Tech’s authorised service centre for inspection, testing, and calibration.

        Assessment Process

        Major Tech’s service lab will assess the returned unit to determine:

        • Whether the fault is due to a manufacturer’s defect (covered under warranty), or
        • If the issue is the result of user error or no fault is found.

        Outcomes

        • If approved under warranty: The product will be repaired or replaced at no cost to you.
        • If not covered under warranty: The lab may offer repair services, which will be quoted and billed directly to you by the service provider.

        Important Notes

        As Major Tech’s service labs are independent providers, Sparky Direct cannot govern or guarantee turnaround times or any costs incurred for repairs outside of warranty coverage.

        Please allow up to 7-14 working days for the return of your product.
