Megger MFT1741 Multifunction Tester, 100V , Earth Resistance Measurement With Bluetooth RS Calibration

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.

• Enhanced non-trip loop impedance measurement technology
