  • Five selectable insulation test voltages at 50, 100, 250, 500, 1000 V cover diverse applications

Compact 2-in-1 insulation multimeter

The Fluke 1587FC combines a true-RMS digital multimeter with an insulation tester in a single handheld unit. Selectable test voltages of 50, 100, 250, 500 and 1000 V cover a wide range of cables, motors and switchgear. Wireless data logging through the Fluke Connect app removes the need to record results manually.

Suited for electricians doing preventive maintenance

Technicians who need both insulation resistance and standard electrical measurements on one instrument benefit from the combined functionality. The VFD low-pass filter supports accurate readings on variable-frequency motor drives. Buyers who only require basic voltage and continuity checks without insulation testing will find simpler devices more appropriate.

Five selectable insulation test voltages

The meter offers discrete test voltages of 50, 100, 250, 500 and 1000 V, letting you match the test level to the equipment under test. This range determines whether the instrument can qualify the insulation class you work with.

Questions about this item

What test-lead connections does the 1587FC need for insulation tests up to 1000 V?

The unit uses standard 4 mm safety test leads and probes rated for the selected insulation voltage; connect them to the dedicated insulation test terminals on the meter.

How do you pair the 1587FC with the Fluke Connect app for the first time, and what step is often missed?

Enable Bluetooth on the meter, open the Fluke Connect Measurements app on your phone, then follow the in-app pairing wizard; the step often missed is granting the app location permission so it can discover the meter.

Which user-replaceable power source does the 1587FC require, and when should it be changed?

It runs on four AA alkaline batteries; replace them when the low-battery indicator appears on the display to maintain accurate insulation and multimeter readings.
