Put your electrical installations through their paces with this multifunction tester from Megger. Its confidence meter analyses readings for accuracy and adjusts for noise when measuring loop impedance. This makes it a cinch to accurately test systems where electrical disturbance tends to butt in. There's no need to worry about juggling your test probes, as the device's automatic start function leaves both your hands free. Colour-coded controls let you quickly pick the process you need, so it's a breeze to use.

The MFT1741 multifunction tester has been designed for testing low voltage electrical installations, particularly in locations that suffer from high electrical noise. It provides all the tests required to complete the necessary electrical certification for industrial, commercial, and domestic fixed wiring installations. Overlaying the new non-trip loop impedance measurement is the new “confidence meter”. As loop impedance values can be dramatically affected by circuit noise, the Confidence Meter displays the degree of confidence in the accuracy of the measured loop impedance.

The MFT1741 includes full input protection and safety warnings when a hazardous voltage is present. If live voltages exist on a circuit during insulation or continuity testing, the voltage is displayed on the screen. If this voltage exceeds a safe level, further testing is inhibited, and a warning beep sounds.

The MFT1741 multifunction tester has a great range of test functions and ideal for, electrical installation testing, verification of low voltage building wiring and distribution testing scenarios.

The MFT1701 series from Megger tests low voltage electrical installations to BS7671. Providing all the tests required to complete the necessary electrical certification for industrial, commercial, and domestic fixed wiring installations. The unique design allows it to be operated while mounted on the floor, a ladder-shelf, platform, and held or hung around the neck.

The MFT1741 is supplied in a large soft pouch and included with the instrument: standard 3-wire lead-set 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 warranty, free of charge.
