It is suitable for industrial, commercial, and domestic applications, ensuring compliance with safety regulations and delivering accurate results. Key features include phase rotation indication, 3-phase RCD testing (even without an earth connection), and on-board data storage with Bluetooth for easy data transfer and reporting. The tester boasts a large, bright dual-parameter LCD display for clear, simultaneous readings of parameters like loop resistance and fault current, or insulation resistance and test voltage. It performs two and three-wire non-trip loop testing for efficient results, comprehensive earth electrode resistance measurements, and is designed for robust performance in various environments. The MFT1721 offers enhanced functionality over the MFT1710, adding auto RCD testing, phase rotation, and 3-phase RCD testing, with the option for current measurement via an optional clamp. It also includes an additional 100V insulation test range, true RMS voltage measurement, an mV sensor input, and Type B RCD testing capabilities.
