Fluke 1587 Insulation Multimeter
Introduction:
The Fluke 1587 FC, 1587, 1587T, and 1577 are battery-powered, true-RMS insulation multimeters (the Product or Meter) with a 6000-count display. Although this manual describes the operation of all models, all illustrations and examples assume use of Model 1587 FC.
The Meter measures or tests:
- AC / DC voltage and current
- Resistance
- Continuity
- Insulation resistance
- Voltage and current frequency
- Diodes (all 1587 models)
- Temperature (all 1587 models)
- Capacitance (all 1587 models)
The 1587 FC supports the Fluke Connect™ Wireless System (may not be available in all regions). Fluke Connect™ is a system that wirelessly connects your Meter with an app on your smartphone or tablet. The app shows the Meter measurement on your smartphone or tablet screen. You can save these measurements with Fluke Connect™ to share with your team.
