Fluke 1535 2500V Insulation TesterThe Fluke 1535 and 1537 2500 V Insulation Resistance Testers are engineered to simplify frontline troubleshooting whether you�re on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2500 V and resistance measurements up to 500 G? these testers allow you to cover more workload with a single tool. Equipped with an intuitive user interface, a short circuit current of up to 5 mA and a CAT IV 600 V rating these portable high-voltage insulation testers can deliver rapid and stable resistance measurements no matter where you take them. The 1537 Insulation Resistance Tester also allows you to store measurements for later review or PC transfer, using the provided software.Selectable Voltage Tests:Tailor your tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V to cover both industrial and solar applications.Extended Insulation Resistance Measurement:Reach up to 500 G? in insulation resistance measurement for a thorough analysis.Intelligent Calculations:Automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.High Measurement Capacity:Execute up to 1,300 measurements at 2500 V or 6,500 measurements at 250 V enhancing productivity. Enhanced Safety Features: Benefit from a CAT IV 600V rating and a built-in voltage alarm function for heightened safety during operations.Includes:Insulation Resistance TesterTest leads with alligator clips (red, black, green)Probe (red, black)Soft carrying case
