The Fluke 1550B is a digital insulation tester capable of testing switchgear, motors, generators and cables at up to 5000 V DC. It can be used for a wide range of tests: from simple spot checks to timed tests and breakdown tests. Measurement storage and PC interface software make it ideal for preventive maintenance. • Test voltages of 250 V, 500 V, 1000 V, 2500 V, 5000 V
• Capable of testing in 50 V increments between 250 V and 1000 V and 100 V increments between 1000 V and 5000 V
• Measures 0 to 1 Tera-Ohm
• Warning voltage function alerts the user that line voltage is present and gives the voltage reading up to 600V AC or DC
• Guard system eliminates the effect of surface leakage current on high-resistance measurements
• Large digital/analog LCD shows detailed measurement data
• Cable or insulation capacitance
• Leakage current
• Ramp function (0-5000 V DC) for breakdown testing
• Timer 1 to 99 minutes
• Polarization index and dielectric absorption calculated automatically
• 99 memory locations store all measurements parameters
• Includes Quicklink 1550B Software and Optical Interface cable
