LT300 Loop Tester The LT300 combines high current-loop testing over a wide range of frequencies and supply voltages with simple operation. This is a HIGH CURRENT ONLY tester, designed for installations where there are no RCDs installed. A two-wire test performs a fast loop impedance measurement at a test current up to 27A, with a resolution of 0.01ohms. Frequency range and operating voltage are wide, allowing for a diverse range of applications up to and including CATIV 550V phase-to-phase. Testing commences automatically as soon as the instrument is connected to the supply. Repeat testing is provided by the TEST button. High current loop tester
