Fluke 1587 Insulation Multimeter (1kV)
The Fluke 1587 FC Insulation Multimeter combines insulation testing with a full-featured digital multimeter. With Fluke Connect wireless capability, you can identify problems, make repairs, and share results quickly and safely from a distance.
Key Features & Connectivity
- Fluke Connect® enabled — monitor measurements remotely via smartphone
- Safety first: stand clear while measurements are acquired remotely
- Wirelessly save, share, and compare measurements; reduce errors in field data entry
- PI / DAR timed-ratio tests with TrendIt™ graphs to detect moisture or insulation degradation faster
- Memory storage in Fluke Connect – no more manual note‑taking
- Temperature compensation to maintain measurement baseline continuity over time
- Historical tracking & asset trending via Fluke Connect® Assets (sold separately)
- VFD low-pass filter for accurate measurements on variable-frequency motors
- Auto-discharge of capacitive voltage for user protection
- Live circuit detection — inhibits insulation test if >30 V present
- Complete measurement capabilities — voltage (AC/DC), mV DC, current (AC/DC/mA), resistance, continuity, capacitance, diode, temperature, frequency
- Min/Max, smoothing, auto power-off, and remote probe included
- Includes remote probe, test leads, alligator clips, K‑type thermocouple, hard case, and a 3‑year warranty
