Product Overview

The FLUKE-1555 CAL is a 10KV insulation tester. It features digital insulation testing up to 10KV, making it as an ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables. Fluke insulation tester can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, 3 year warranty and CAT IV 600V safety rating. With measurement storage and PC interface, the 1555 is perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. Warning function alerts user that line voltage is present and gives voltage reading up to 600VAC or DC for increased user safety. Measurements can be stored in up to 99 memory locations with each location assigned a unique, user defined, label for easy recall. It has automatic calculation of dielectric absorption (DAR) and polarization index (PI) with no additional set-up.
