It provides all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations. The MFT1845+ includes a new non-trip loop testing technology that prevents any influence that the RCD may present to the total loop impedance value and has non-trip loop testing down to 8 seconds. This technique also allows testing of loop impedance through 10 mA type AC and Type A RCDs. 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.
