Multifunction Electrical Installation Tester, 600V - 

MFT1711 is a MFT1701 series multifunction installation tester. The Confidence Meter™ technology is ideal for enhanced Earth Loop Impedance testing in electrically noisy environments. Traditional Loop Impedance method is susceptible to circuit noise during the measurement phase. If the AC waveform changes during this period, from noise or harmonics, the distortion can create significant variation from test to test. The Confidence Meter™ analyses and adjusts and it provides a far more stable result every time, removing the need for repeated tests. This IEC 61010 CAT IV 300V rated for connection to low voltage systems with no protective device, so safe for connection anywhere on the system right up to the source transformer without risk of damage from large transient spikes. Safety approvals are IEC 61010-1:2010, IEC 61010-30:2010, IEC 61010-031:2008, 600 V CAT III / 300 V CAT IV (Max Phase to Phase 600 V), IEC 61557:2007 parts 1 to 10.
