        Major Tech MT350 | Loop Impedance And PSC Tester

        Description:

        The MT350 is a handheld microprocessor controlled Loop Impedance and PSC Tester, which includes 3 loop impedance measuring ranges capable of measurements from any point in the installation for comprehensive testing of distribution systems. The MT350 gives a direct readout of PSC and earth fault current to a maximum of 20kA in 3 measuring ranges. Other features include 3 LED’s for checking the correct wiring status of the circuit under test and the automatic lockout if the resistors overheat. The meter is supplied in double injection rubber housing.

        Features:

        • CAT IV 600V and CAT III 1000V
        • Custom microprocessor controlled for highest accuracy and reliability
        • Loop impedance of 2000Ω range measurement is carried out with low test current (15mA)
        • Automatic Lock-Out if Test Resistor Overheats
        • Direct readout of Prospective Short Circuit Current and Earth Fault Current
        • Measures low loop impedance of 0.01Ω
        • 3 LED’s for checking correct wiring status
        • Safe voltage measurement function
        • Visual indication of reversed phase and neutral at wiring socket
        • Double injection rubber housing

        Assessment Process

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

        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.
