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 0.01 ohms. Frequency range and operating voltage are wide, allowing for a diverse range of applications, and testing commences automatically as soon as the instrument is connected to the supply. Repeat testing is provided by the TEST button.
