Core Features of the Megger MFT1721:
- True RMS voltage and frequency measurement (TRMS) for accurate readings on all waveforms.
- Insulation resistance testing at 100 V, 250 V, 500 V, and 1000 V – ideal for a wide range of installations.
- Safety protection against live circuits up to 600 V – even with insulation lock-on.
- Continuity testing at 200 mA or 15 mA with fast-response buzzer.
- Earth loop impedance testing with both 2- and 3-wire non-trip methods.
- High-current loop testing, including phase-to-phase up to 500 V.
- Prospective fault current (PFC) measurement up to 20 kA.
- RCD testing for Type AC, A, S, and programmable RCDs – includes Type B for EV charging stations and 3-phase RCDs.
- Auto-RCD testing routines to speed up workflows.
- Displays fault (touch) voltage during RCD testing.
- Optional clamp enables current measurement.
Durable and Portable
The megger mft1721 multifunction tester comes in a rugged, moulded case to protect it during tough site conditions. It’s compact, easy to carry, and ideal for both beginners and experienced engineers. While the megger 1721 ships with a hard case, higher models like the MFT1731 come with a soft pouch and extra accessories.
