Product Overview

The Fluke 1587 FC (Part Number: FLUKE-1587 FC / 4691215) is a high-performance, 2-in-1 diagnostic tool that combines a digital insulation resistance tester with a full-featured, true-RMS digital multimeter into a single, compact, handheld device. Engineered for electricians, industrial automation technicians, and field service professionals, it provides maximum versatility for troubleshooting and preventative maintenance on motors, generators, cables, and switchgear.

By integrating Fluke Connect® wireless technology, the 1587 FC allows technicians to safely capture, store, and share measurement data with their smartphones from a safe distance. The app unlocks advanced diagnostic capabilities, including TrendIt™ graphs, automated PI/DAR (Polarization Index / Dielectric Absorption Ratio) timed ratio tests, and temperature compensation for accurate baseline tracking over time.

Key Features

• 2-in-1 Functionality: Eliminates the need to carry two separate meters by merging an advanced insulation tester with a precision true-RMS multimeter.

• Fluke Connect® Wireless Compatibility: Transmits measurements wirelessly to the Fluke Connect mobile app, allowing you to view readings safely from a distance, eliminate manual data entry, and trend asset health over time.

• Advanced Insulation Diagnostics: Performs timed PI/DAR ratio tests with TrendIt™ graphing to quickly identify moisture and contaminated insulation problems.

• Multiple Test Voltages: Offers five selectable insulation test voltages—50 V, 100 V, 250 V, 500 V, and 1000 V—covering resistance measurements from 0.01 MΩ up to 2.0 GΩ.

• VFD Low-Pass Filter: Features a selectable low-pass filter for accurate voltage and frequency measurements on variable frequency drives (VFDs) and noisy motor drive equipment.

• Enhanced Safety Protection: Includes live circuit detection that automatically stops an insulation test if a voltage greater than 30 V is detected, along with auto-discharge of capacitive voltage for user protection.

• Full Multimeter Capabilities: Measures true-RMS AC/DC voltage up to 1000 V, DC millivolts, AC/DC milliamps, resistance, continuity, capacitance, diode test, frequency, and temperature.

Common Questions (FAQs)

Q: What is the difference between the standard Fluke 1587 and the Fluke 1587 FC?
A: The "FC" stands for Fluke Connect. While the core measurement specifications remain identical, the 1587 FC adds wireless Bluetooth connectivity to sync with the Fluke Connect mobile app. This unlocks advanced diagnostic features not available on the legacy model, including automated PI/DAR timed ratio tests with TrendIt™ graphing, temperature compensation, and cloud-based data storage for historical asset tracking.

Q: Why is the PI/DAR ratio test important, and how does Fluke Connect help?
A: Polarization Index (PI) and Dielectric Absorption Ratio (DAR) tests are timed insulation tests that help differentiate between normal surface leakage (e.g., from dirt or humidity) and true insulation breakdown. Through the Fluke Connect app, the meter automatically performs these timed calculations and graphs them visually using TrendIt™, eliminating manual stopwatch calculations and reducing transcription errors.

Q: How does the remote test probe work?
A: The included remote probe features a built-in test activation button on the handle. When performing insulation resistance tests in tight or awkward cabinet spaces, you can press the button directly on the probe to initiate the test without needing a third hand to press the "TEST" button on the multimeter face.

Q: Can the Fluke 1587 FC measure high AC currents?
A: The meter itself measures AC/DC current up to 400 mA directly through its test leads. For higher AC current measurements without breaking the circuit, the 1587 FC is compatible with external current clamp accessories, such as the Fluke i400 AC Current Clamp (sold separately or included in the 1587/MDT Troubleshooting Kit).

Q: What happens if I accidentally try to perform an insulation test on a live circuit?
A: To protect the user and the tool, the Fluke 1587 FC features integrated live circuit detection. If the meter detects a voltage greater than 30 V across the terminals, it will automatically inhibit the insulation test and warn the technician. Additionally, the meter automatically discharges any remaining capacitive voltage from the tested circuit after the test button is released.
