Fluke 374 FC True-RMS Clamp Meter

Fits everyday True-RMS clamp work on feeders and motors where jaw AC/DC to 600.0 A is enough, with optional iFlex AC to 2500 A, voltage to 1000 V, resistance to 6000 Ω, and Fluke Connect logging — part of the 370 FC series with soft case and TL75 leads included per notes.

Key advantages

True-RMS clamp — AC/DC current to 600.0 A via jaw; optional iFlex AC to 2500 A.
Voltage and more — AC/DC voltage to 1000 V plus resistance and capacitance on banana jacks.
Fluke Connect — wireless logging/reporting for field records (no analog output).
Published accuracy bands — jaw AC 2% ±5 digits (10–100 Hz); DC current 2% ±5 digits.

Typical applications

Electrical maintenance current and voltage checks on industrial panels.
Jobs needing iFlex flexible probe reach for large conductors.
Teams logging clamp readings via Fluke Connect.

Display — Backlit digital display; Min/Max/Avg and inrush recording.
Communication — Fluke Connect (Bluetooth).
Approvals — CAT III 1000 V, CAT IV 600 V, True-RMS.
Mounting — Handheld clamp meter; optional TPAK magnetic hanger.

Common mistakes

Expecting frequency or mV DC ranges listed on 375/376 FC — 374 FC JSON lists resistance to 6000 Ω and capacitance to 1000 µF without a frequency clause; lock features you need against the 370 FC family sheet.
Assuming iFlex is included — listed as optional flexible current probe.

FAQ

Q: How does 374 FC differ from 375 FC? A: Both jaw 600 A AC/DC with optional iFlex 2500 A. 375 FC JSON adds frequency to 500 Hz and mV DC 500.0 mV; 374 FC lists resistance to 6000 Ω. Lock features on the RFQ.

Q: Is iFlex included? A: Optional per clean sample — state if it must ship in the kit.

Q: What should I send for a quote? A: Current path, iFlex need, quantity. Compatible with systems using Fluke 374 FC — we do not claim authorized-dealer status.
