FLUKE 1550B Megohmmeter/Insulation Resistance Tester
The Fluke 1550B is a digital megohmmeter 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. The Fluke 1550B executes everything from simple spot checks to timed tests and breakdown evaluations. It even stores test results and downloads them to your PC via infrared port.
Features of the FLUKE 1550B Megohmmeter/Insulation Resistance Tester Include:
- Standard test voltages of 250 V, 500 V, 1000 V, 2500 V and 5000 V
- Additional test voltages available in 50 volt steps from 250 to 1000 volts, 100 volt steps from 1000 to 5000 volts
- Measures up to 1 Tera-Ohm
- Warning voltage function alerts the user that line voltage is present and gives the voltage reading up to 600 V ac or dc
- Automatic calculation of Dielectric Absorption and Polarization Index with no setup
- Guard system eliminates the effect of surface leakage cur on high-resistance measurements
- Large digital/analog LCD delivers detailed measurement data
