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. 
More information about how to use Fluke Connect is on 
page 30.
