Description

The FLUKE 1503 Insulation Resistance Tester is a rugged, compact, and reliable testing instrument designed for accurate insulation and electrical measurements in residential and commercial environments. Built to meet the demands of professional electricians and technicians, this tester combines safety, precision, and ease of use in one durable unit.

The Fluke 1503 performs insulation resistance testing from 0.01 MΩ to 2000 MΩ, making it suitable for evaluating the condition of cables, motors, and electrical installations. It offers two insulation test voltages—500 V and 1000 V, providing flexibility for a wide range of testing requirements. For enhanced safety, the tester includes live circuit detection, preventing insulation testing if voltages above 30 V are present.

In addition to insulation testing, the Fluke 1503 measures resistance from 0.01 Ω to 20.00 kΩ and AC/DC voltage from 0.1 V to 600 V, allowing technicians to perform multiple electrical checks with a single instrument. The built-in auto-discharge of capacitive voltage further enhances user protection after testing.

Designed for field efficiency, the tester features a large, backlit display for clear visibility in low-light conditions and auto power-off to conserve battery life. It is rated CAT IV 600 V, ensuring a high level of overvoltage protection for demanding applications. The lo-ohms earth-bond continuity function (200 mA) supports reliable grounding and bonding verification.

The Fluke 1503 also simplifies repetitive or hard-to-reach testing with an included remote test probe, and it is compatible with the optional Fluke TPAK magnetic hanging system, enabling hands-free operation when needed. Powered by four AA alkaline batteries, the tester delivers at least 1,000 insulation tests on a single set of batteries.
