Fluke 1587 FC Insulation Multimeter

Fits field insulation and electrical troubleshooting when you need selectable megohm test voltages plus a True-RMS DMM in one handheld with Fluke Connect reporting.

Key advantages

2-in-1 insulation + DMM — About 0.01 MΩ–2 GΩ insulation plus True-RMS DMM functions with VFD low-pass filter.
50–1000 V test set — Selectable insulation voltages 50 / 100 / 250 / 500 / 1000 V.
CAT III 1000 V / CAT IV 600 V — Live-circuit detection inhibits insulation test if voltage is present.
Fluke Connect — Wireless reporting with PI/DAR timed ratio tests, memory, and temperature-compensation options.

Typical applications

Motor, cable, and switchgear insulation surveys in the field.
Sites that want megohm tests and everyday True-RMS DMM checks in one tool.
Teams logging PI/DAR and insulation results via Fluke Connect.

Selection guide

Insulation range — About 0.01 MΩ to 2 GΩ (1587 FC).
Test voltages — 50 / 100 / 250 / 500 / 1000 V.
DMM — True-RMS functions; large backlit display; VFD low-pass filter.
Safety — CAT III 1000 V / CAT IV 600 V; live-circuit detection inhibits insulation test if voltage present.
Connectivity — Fluke Connect wireless reporting; PI/DAR timed ratio tests; memory; temperature compensation options.

Common mistakes

Picking a low test voltage (50/100 V) when the insulation class needs 500/1000 V — match voltage to the asset.
Expecting insulation test to run on a live circuit — live-circuit detection inhibits the test if voltage is present.
Treating Fluke Connect PI/DAR / temperature compensation as available without the wireless/app path on site.
Assuming CAT III 1000 V / CAT IV 600 V covers every bus — verify the measurement location against the category.

When to RFQ / what to tell us

Required insulation test voltages (50–1000 V set) and primary DMM vs megohm use.
Fluke Connect / PI-DAR / temperature compensation yes/no.
Quantity, ship-to, CAT III 1000 V / CAT IV 600 V confirmation.

FAQ

Q: Insulation tester or DMM — what does 1587 FC cover? A: Both: insulation about 0.01 MΩ–2 GΩ at 50/100/250/500/1000 V, plus True-RMS DMM functions with VFD filter. State daily use on the RFQ.

Q: Will it megohm-test a live circuit? A: No — live-circuit detection inhibits the insulation test if voltage is present.

Q: What should I send for a quote? A: Test voltages, CAT needs, Fluke Connect yes/no, quantity, ship-to. Compatible with systems using Fluke 1587 FC — we do not claim authorized-dealer status.
