Megger MFT1721: The new advanced level, 18th Edition Multifunction Tester

The new MFT1700 series has been designed for tough environments and ultimate reliability. Features include a rubber over mould for extra protection and grip, IP54 protection against dust and water and an EN61010 Cat IV safety rating. Its class leading input protection ensures the MFT can withstand accidental misuse and voltage transients when other testers can’t. All this in an intuitive and easy to use instrument with no hidden menus or complicated screens.

*Important Calibration Information:

This instrument comes complete with a manufacturers calibration certificate. Please be aware that these certificates are generic and may also be time lapsed. If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.

The Megger MFT1700 Series Comes Supplied With:

Printed quick start guide
Full user guide on CD
Manufacturer's Calibration Certificate
Switched Probe SP5 (not supplied with MFT1711)
Neck strap - Megger embroidered
3 Wire lead set with prods and clips
Mains plug test lead (BS1363 (LT300-EN-BS)
AC battery charger (MFT1731 only)

The MFT1700 series is a range of 3 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:

System voltage and frequency measurement TRMS
Insulation 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
Prospective fault current measurement up to 20 kA
RCD testing including: Type AC, A, S, B* and programmable RCDs, 3-phase RCDs*, Auto-test routine, Fault (Touch) voltage display
Earth spike testing: 2-pole/3-pole, ART, Stakeless techniques

Tests are easily selected using the colour coded rotary switches with results clearly displayed on the high contrast, dual measurement, backlit display. Included with the instrument: standard 3-wire leadset and a mains test lead, a switched probe for fast and easy testing*, a full 12-month calibration certificate and warranty upgradeable to 3 years. The MFT1711 and MFT1721 are supplied in a robust moulded case, and the MFT1731 is supplied in a large soft pouch with plenty of additional space for optional extras like a few tools and the earth electrode test kit, comprising 2 spikes and 3 long test leads.
