"Save money when you buy the Fluke 1664 FC Installation Tester, the Fluke T150 Voltage & Continuity Tester and the DMS software together in this great value bundle.The Fluke 1664 FC Installation Tester is a tester that helps prevent damage to connected appliances, reduces test time and features Fluke Connect. Incorporated is Insulation-PreTest, a feature that allows the tester to determine if system under test has an appliance connected. If an appliance is detected the 1664 FC stops the test, helping to eliminate accidental damage. To reduce test time the 1664 FC also offers an auto test function. One button press initiates a predefined sequence of seven tests. Compared to previous Fluke models this feature can save up to 40% in time. The featured Fluke Connect allows measurements to be sent to a centralised cloud-based server, the Fluke Cloud. Data can be uploaded via a smartphone with the Fluke Connect app in real time. Making it easy to record, analyse and share data with colleagues from the field.Loop Impedance Test Type = Phase to Earth, Phase to NeutralAutomatic RCD Test = YesRCD Ramp Test = YesInsulation Test Voltage = 50 V, 100 V, 250 V, 500 V, 1000 VMaximum Voltage Measurement = 500V ac\/dcTest Type = Continuity, Frequency, Insulation Resistance, Loop and Line Resistance, Measure Motor Windings, Phase Sequence Test, Prospective Earth Fault Current, Prospective Short Circuit Current, RCD Test, Resistance, Voltage, Wiring PolarityEarth Resistance Measurement = YesDownloadable Data = YesInterface Type = UK MainsContinuity Test Current = 10mA"
