The 5030 is a precision instrument designed to calibrate RCD, loop, insulation, earth testers and multifunction installation testers. It accurately simulates RCD trip times and measures currents produced by RCD testers. It replicates loop impedance and auto adjusts for local line impedance. It also provides insulation resistances and measures test voltages and currents.

User control is via the central navigation keypad. Scrolling though menus and settings is intuitive and easy, with measurements and settings shown on the LCD display. For loop and RCD tests the electrical tester connects directly to the dedicated front panel mains socket (regional type sockets available, specified on order). In these test conditions, if the device under test is faulty, the 5030 auto detects the fault, disconnects the output and warns the user. The 5030 is designed not to trip any RCDs on the local supply. For insulation and continuity, connection is via 4 mm terminals.

Software driven calibration can be performed by connecting the 5030 to a PC/laptop installed with EasyCal software.
