The Fluke 1537 2500 V Insulation Resistance Tester is engineered to simplify frontline troubleshooting whether on the factory floor or working in the field at a solar installation site. With user selectable test voltages from 250 V to 2500 V, and resistance measurements up to 500 GΩ, this tester allows 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 this portable high-voltage insulation tester can deliver rapid and stable resistance measurements no matter where the user takes it. The 1537 Insulation Resistance Tester also allows users to store measurements for later review or PC transfer, using the provided software.

Selectable Voltage Tests: Users can tailor tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V, covering both industrial and solar applications.

Extended Insulation Resistance Measurements: The 1537 can reach up to 500 GΩ in insulation resistance measurement for a thorough analysis.

Intelligent Calculations: This tester automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.

High Measurement Capacity: The 1537 executes up to 1,300 measurements at 2500 V or 6,500 measurements at 250 V enhancing productivity.

Enhanced Safety Features: User can benefit from a CAT IV 600V rating and a built-in voltage alarm function for heightened safety during operations.

Extended Measurements: The Fluke 1537 enhances user's 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 that users can focus on testing procedures 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.
