| The redesigned Fluke 1550C insulation resistance tester, offer digital insulation testing up to 10kV, making it 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 and 1550C are perfect tools for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.  Testing to 5 kV (1550C) or 10 kV (1555)  CAT III 1000 V, 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 above 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 |
