Quickly configure, start and stop tests on the 1550C remotely, a safe distance away from any operating, energized equipment, using Fluke Connect" and a smart phone Guard system eliminates the effect of surface leakage current on high-resistance measurements Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety Real time trending gives you easy-to-see visual cues, rather than hard to read, rapidly changing values Report creation using Fluke Connect desktop saves time and makes test results easier to understand Fluke Connect saves test results to the cloud for analysis and preventive maintenance Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
