The Fluke 1503 Insulation Tester combines industry‑grade safety and performance, designed for commercial and industrial electrical insulation testing. Featuring a maximum reading of up to 2 GΩ and dual test voltages of 500 V and 1000 V, it is rated for CAT III 600 V / CAT IV 600 V use (depending on region), ensuring high‑level over‑voltage protection. Compact and rugged, the 1503 supports a complete suite of insulation resistance, voltage, and continuity measurements, with live‑circuit detection and auto‑discharge for operator safety.

Core Capabilities of the Fluke Insulation Tester

  • Insulation test range from 0.01 MΩ to 2000 MΩ, supporting wide‑span insulation integrity checks.
  • Dual test voltages (500 V / 1000 V) enable matching to equipment insulation ratings.
  • CAT III 600 V / CAT IV 600 V safety rating permits use in demanding environments.
  • Live‑circuit detection blocks insulation testing when the terminal voltage exceeds 30 V, enhancing user protection.
  • Backlit display and compact form‑factor (550 g weight) suit field and workshop deployments.
  • Includes remote probe, test leads, probes and alligator clips for a complete test setup out of the box.

Built for Industrial Electrical Maintenance

This is engineered to provide dependable insulation resistance diagnostics for industrial panels, electrical installations, and commissioning workflows. Its rugged design withstands jobsite conditions, while the auto‑discharge functionality removes stored capacitance before readings, reducing risk.

Usage Information of the Product

  • Commissioning of industrial electrical switchgear and motor circuits.
  • Insulation verification in preventive maintenance regimes for motors, generators and control systems.
  • Field testing of building wiring installations and large‑scale electrical distribution.
  • Verification of insulation resistance after repair or refurbishment on electrical equipment.
  • Environments where a high measurement safety rating (CAT III/IV) is required for live‑system proximity.
