Megger MFT1721 Multifunction Tester

Megger MFT1721 Multifunction Tester

The most popular of the range of 18th Edition testers offering all the benefits of the MFT1710, including auto RCD testing and adding phase rotation, 3-phase RCD testing and current measurement with the optional clamp.

This now adds an additional 100V insulation test range, true RMS voltage measurement, mV sensor input and Type B RCD testing.

• Two and three wire non trip loop testing for fast repeatable results
• Large bright LCD display showing dual parameters - loop resistance and fault current, insulation resistance and test voltage
• Phase rotation indication for verification of rotating machinery
• 3-phase RCD testing for industrial applications with no earth
• Suite of earths test for electrode resistance measurement
• On-board data storage and Bluetooth® download

This latest series of multifunction installation tester adds one to the nomenclature and vastly to the value of these testers. The range of 3 instruments are expressly for testing low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations.

The MFT1701 series is a range of 4 instruments for testing low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations, including:

• TRMS System voltage and frequency measurement
• nsulation test at 100 V*, 250 V, 500 V and 1000 V Including input protection against live circuits up to 600 V even when insulation test is locked-on
• Continuity resistance at 200 mA or 15 mA
• Automatic start - no need to press TEST so leaving both hands free to hold probes
• Resistance range up to 100 kΩ with fast continuity buzzer at selectable thresholds
• Earth loop test
• 2 and 3 wire non-trip range
• 2 wire Hi current including phase to phase
