Megger MFT1741+ Multifunction Tester

Megger Components Shortage PLEASE NOTE: Megger is currently experiencing a global shortage of components for their popular MFT 1700 Series. We are currently operating a waiting list and as stock becomes available we will ship your order. If you would like to get your hands on these industry-leading MFT's, then we strongly advise that you get in the queue. The Megger MFT1741+ multifunction tester is an instrument designed for testing low voltage electrical installations and especially 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. The MFT1741+ offers a wide range of test functions, designed for all electrical installation testing and verification of low voltage building wiring and distribution testing scenarios. The MFT1741+ is IEC 61010 CAT IV 300 V rated for safe connection anywhere within the LV network on single and 3 phase systems. New Loop Impedance testing technology Prevents any influence the RCD may present to the total loop impedance value. Faster non-trip loop testing down to 8 seconds. This technique also allows testing of loop impedance through 10mA type ac and Type A RCDs. New “Confidence meter*” measurement analysis (Patent pending) Overlaying the new non-trip loop impedance measurement is the new Megger “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. Using the digital ARC to indicate the analytical process, the measurement is continually monitored and adjusted when circuit noise is present, resulting in a dramatically improved and repeatable test result. New electric vehicle charge point testing The MFT1741+ includes an automatic EV Charge Point RCD test sequence, including the 6 mA dc test*. Test results can be reviewed or saved to memory and reviewed later. FEATURES Testing of Electric Vehicle Charge Points*.
