Combine the IR3000 FC Connector and Fluke Connect ® , to perform advanced insulation testing for preventive and PdM tasks through: • PI (polarity index) and DAR (dielectric absorption ratio) tests with TrendIt™ graphs to identify problems faster
• Wireless transfer of test results from the tool to Fluke Connect ® eliminates error-prone paperwork and saves your technician’s time • Temperature Compensation through Fluke Connect ® App helps establish accurate baselines and relevant historical comparisons
