Fluke 1535 and 1537 Insulation Resistance Tester and Megohmmeters

The Fluke 1535 and 1537 Insulation Resistance Tester and Megohmmeters are engineered to simplify frontline troubleshooting whether on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 GΩ these testers allow users 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. The 1537 Insulation Resistance Tester also allows the user to store measurements for later review or PC transfer, using the provided software. The Fluke 1537 has these additional features: Extended Measurements: The Fluke 1537 enhances your testing capabilities with AC/DC voltage and resistance measurements.Stable Resistance Measurements: Achieve faster, more stable insulation resistance measurements with a short circuit current up to 5mA.Fine-tunable Test Voltage: Adjust the test voltage from 250 V to 2500 V in 100 V increments to meet specific testing requirements.Dielectric Discharge Rate Calculation: Automatically calculate the dielectric discharge rate (DD) to aid in identifying elusive insulation issues.Ramp Test Mode: Linearly increase the applied test voltage 100 V/s to help identify potentially hard to identify fault conditions.Visual and Audio Continuity Indicator: Verify continuity visually on the screen display or with the audible indicator so you can focus on your testing procedure without looking at the display.Customizable Testing Parameters: Set user-defined labels, adjust test duration, and store measurement results for a tailored testing experience.Effortless Data Management: Download and manage data effortlessly with the provided PC software.Extended Warranty: Enjoy peace of mind with an extended 3-year warranty.
