Fluke Corporation warrants its 1550C/1555 Insulation Tester for three years from the date of shipment.
The Fluke 1550C and 1555 Insulation Testers are high-voltage devices designed to validate general circuits such as switchgear, motors, and cables. The unit features a large LCD, six preset test voltages (with the 1555 model offering an additional 10,000 V option), and programmable test voltages ranging from 250 V to 10,000 V. Key capabilities include measuring resistance from 200 kΩ to 2 TΩ, calculating Polarization Index (PI) and Dielectric Absorption Ratio (DAR), and utilizing a ramp mode that linearly increases voltage at 100 V/s. The device also includes a test timer, result storage with user-defined ID tags, and a breakdown voltage indication. It is powered by a rechargeable lead-acid battery and features an infrared (IR) port for downloading data to a PC using the supplied FlukeView Forms Basic software.
