The MT350 is a handheld Loop Impedance and PSC Tester that is microprocessor controlled, 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. Accessories: Carrying Case Distribution Board Test Leads Magnetic Strip Croc Clips Plug Cord with IEC Connectors 6 x AA Batteries Instruction Manual Features : 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
