Description
Product Details:
The Megger MFT1741 Multifunction Tester is suitable for conducting full single- and three-phase insulation testing. As indicated above it is able to conduct single- and three-phase RCD testing between 10mA and 1A.
The Megger MFT1741 Multifunction Tester’s NEW non-trip loop impedance testing technology also enables loop impedance testing of 10mA type AC and A RCDs. Additionally, NEW non-trip loop impedance technology prevents RCDs from influencing the total loop impedance value and increases the speed of testing: non-trip loop impedance tests can be performed in eight seconds.
Furthermore, loop impedance tests are accompanied by a Confidence Meter, a NEW feature present on the Megger MFT1741 Multifunction Tester. The meter will indicate the degree of confidence in the accuracy of the loop impedance measurement. This feature is useful as loop impedance values are particularly susceptible to changes in circuit noise. The Confidence Meter is designed to improve reliability; the digital ARC indicates the analytical process, and the measurement is continually monitored and adjusted in reference to the circuit noise.
