The Fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kV, making them ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables.
Fluke insulation testers 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 600 V safety rating. With measurement storage and PC interface, the 1555 is the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur.
Product Highlights
Test voltages up to 10 kV provides solutions for all applications
CAT IV 600 V safety rating
Voltage breakdown detection alerts the user that voltage is present and gives the voltage reading up to 600 V ac or dc for increased user safety
Selectable test voltages in 50 V steps from 250 to 1000 V, and 100 V steps 1000 V
Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
Long battery life gives the user over 750 tests between charges
Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
Guard system eliminates the effect of surface leakage current on high-resistance measurements
Large digital/analog LCD for easy viewing
Capacitance and leakage current measurement
Ramp function for breakdown testing
Resistance measurements up to 2TΩ
Timer settings up to 99 minutes for timed tests
3-year warranty
Each Unit Includes
Test cables with alligator clips (red, black, green)
The tester's accuracy is specified for one year after calibration at operating temperatures of 0°C to 35°C. For operating temperatures outside the range (-20°C to 0°C and 35°C to 50°C), add ±.25% per °C, except on the 20% bands add ±1% per °C.
