Built For Professional Insulation And Electrical Troubleshooting

• The Fluke 1587 FC is best suited for professionals who need insulation testing and multimeter measurements in one handheld tool. It supports maintenance and troubleshooting work involving motors, windings, VFD-related environments, cable insulation checks, and general electrical measurements where a true RMS meter and insulation tester are both useful.
• Key supported capabilities include Fluke Connect wireless measurement support, a VFD low-pass filter, CAT IV 600 V / CAT III 1000 V safety rating, 50, 100, 250, 500, and 1000 V insulation test voltages, and a 0.01 MOhm to 2 GOhm insulation measurement range.

Buying FAQ

Is the Fluke 1587 FC worth the price?

The Fluke 1587 FC makes the most sense when you regularly need both insulation testing and true RMS multimeter functions for professional maintenance or troubleshooting. Its value comes from combining two major tool roles in one meter, adding Fluke Connect support, and covering insulation test voltages from 50 V to 1000 V. If you only need a basic multimeter or occasional electrical checks, a simpler meter may be enough.

What comes with the Fluke 1587 FC?

Package contents include a remote probe, test leads, alligator clips, K-type thermocouple, and hard case. Check the package when it arrives and review the Specs and Manual tabs on this page for setup and operating details.

What does Fluke Connect add to the Fluke 1587 FC?

Fluke Connect support can help with wireless measurement workflows from a supported mobile device. It is useful when readings need to be monitored, saved, compared, or documented without relying only on handwritten notes. For the latest app features and supported workflows, review the official Fluke Connect documentation before field use.

What are PI and DAR tests on the Fluke 1587 FC?

PI, or polarization index, and DAR, or dielectric absorption ratio, are insulation diagnostic tests used to evaluate insulation behavior over time. They are most relevant for professional maintenance and troubleshooting work where insulation condition matters. Use the official manual for exact setup, timing, result display, and interpretation.

What insulation test voltages does the Fluke 1587 FC support?

The Fluke 1587 FC supports 50, 100, 250, 500, and 1000 V insulation test voltages. Product-truth evidence also supports an insulation measurement range of 0.01 MOhm to 2 GOhm.

Can I use the Fluke 1587 FC without the remote probe?

The remote probe is included as part of the supported package contents and is useful for insulation-test workflow. For accepted lead, probe, and test setups, follow the official Fluke manual. Do not rely on unofficial forum repair or modification advice for probes, leads, or input jacks.

What should I check when the meter arrives?

Before field use, verify that the model is Fluke 1587 FC, confirm SKU or order details where visible, inspect package condition, confirm included accessories, review the Specs and Manual tabs, and run basic checks according to the official manual. If the product, accessories, or readings do not match expectations, contact TestingLab support before relying on the meter for field work.

What should I do if the meter shows a battery, calibration, or test error?

Stop and check the official manual first. Confirm battery condition, setup, leads, and test procedure according to the manual.
