The Fluke 1550 MegOhmMeter provides insulation resistance testing up to 1 TW, with four output voltages |
The Fluke 1550 MegOhmMeter is a rugged, easy-to-use, multi-function insulation resistance tester that includes everything electrical technicians need to do their jobs quickly and easily. The digital megohmmeter is capable of testing switchgear, motors, generators, and cables at up to 5000 V dc and 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 1550 MegOhmMeter provides insulation resistance testing up to 1 TW, with four output voltages: 500 V, 1000 V, 2500 V, 5000 V. Its live voltage indicator alerts notify the user that voltage is present and gives the voltage reading up to 600 V ac or dc. The 1550 includes features you expect on higher-end testers, including a ramp function (0-5000 V dc) for breakdown testing, a timer for dielectric absorption, plus the ability to conduct current leakage tests and cable or insulation capacitance tests. Its 99 memory locations store all measurement parameters, which can then be downloaded to a Windows¡°-based computer using the Quicklink 1550 software and optical interface cable that come with the meter.
Easy to use with a large, fast-responding analog/digital display, the Fluke 1550 shows measurement changes graphically with easy-to-read analog bar graphs as well as digital measurements. The last-reading memory display is ideal for insulation resistance and lo-ohms.
The Fluke 1550 is powered by a high-capacity, rechargeable, 12-V battery that provides enough energy for up to 2,500 tests. |
