FLUKE-1503 Insulation Resistance Meter
The Fluke 1503 Insulation Resistance Meter is a rugged and easy-to-use tool ideal for residential and commercial electricians. It supports insulation testing from 0.01 MΩ to 2000 MΩ using two selectable test voltages (500 V and 1000 V. The device includes live circuit detection that prevents testing when voltages exceed 30 V for added safety. With a built-in remote test probe, the 1503 simplifies repetitive testing and enhances user convenience. It also features AC/DC voltage measurement up to 600 V, low-ohms continuity testing with 200 mA, auto-discharge of capacitive voltage, and a large backlit display for better readability in all environments.
