Key parameters
Fits non-contact current and voltage checks on feeders and motors when jaw opening or ampacity exceeds a standard clamp — 999.9 A via jaw, 2500 A AC via included iFlex, with Fluke Connect logging.
Key advantages
- Jaw 999.9 A + iFlex 2500 A — AC/DC via 34 mm jaw; AC to 2500 A on included 18-inch iFlex.
- True-RMS clamp — AC current jaw 2% ±5 digits (10–100 Hz); V AC/DC to 1000 V.
- CAT III 1000 V / CAT IV 600 V — IEC 61010 marks for feeder and motor checks.
- Fluke Connect + TPAK — Bluetooth logging and magnetic hanger included.
Typical applications
- Feeder and motor current checks where jaw or ampacity exceeds a compact clamp.
- Awkward conductors that need iFlex flexible current probe access.
- Maintenance rounds that log clamp readings over Fluke Connect.
Selection guide
- Current — AC/DC via jaw 999.9 A; AC via iFlex 2500 A. Jaw opening 34 mm; 18-inch iFlex included.
- Voltage / other — V AC/DC 1000 V; resistance to 60 kΩ; capacitance 1000 μF; frequency to 500 Hz.
- Accuracy — AC current jaw 2% ±5 digits (10–100 Hz); iFlex 3% ±5 digits; V AC 1% ±5 digits (20–500 Hz); V DC 1% ±5 digits.
- Safety category — CAT III 1000 V / CAT IV 600 V (IEC 61010-1, IEC 61010-2-032, IEC 61010-2-033).
- Display / logging — Backlit display; Fluke Connect Bluetooth (FCC ID T68-FBLE). Display / Fluke Connect wireless logging — no process 4–20 mA output.
- Supply — 2× AA (NEDA 15A / IEC LR6).
- IP / ambient — IP30 (IEC 60529, non-operating); operating −10…+50 °C; storage −40…+60 °C.
- Mounting / kit — Handheld; TPAK magnetic hanger included. Size 249×85×45 mm; weight 395 g.
Common mistakes
- Expecting DC current on the iFlex path — iFlex is listed for AC to 2500 A; jaw covers AC/DC to 999.9 A.
- Assuming IP30 covers wet outdoor use — rating is non-operating; plan handling accordingly.
- Ignoring frequency bands on accuracy (jaw 10–100 Hz; V AC 20–500 Hz) when measuring VFDs or high-frequency content.
- Treating this as a process transmitter — output is display / Fluke Connect logging only, not a loop signal.
- Undersizing jaw opening (34 mm) for large bus bars — use iFlex when the conductor will not fit the jaw.
When to RFQ / what to tell us
- Max AC/DC current expected (jaw vs iFlex path) and conductor size vs 34 mm jaw / iFlex wrap.
- Voltage class and whether CAT III 1000 V / CAT IV 600 V is enough for the measurement point.
- Need for Fluke Connect logging / TPAK hanger yes/no.
- Ambient (must fit −10…+50 °C operating) and quantity / ship-to country.

FAQ
Q: When do I use the jaw vs iFlex? A: Jaw for AC/DC to 999.9 A when the conductor fits the 34 mm opening. iFlex for AC to 2500 A or awkward conductors that will not fit the jaw. State max current and conductor size in the RFQ.
Q: Does it output 4–20 mA to a PLC? A: No. Output is display / Fluke Connect wireless logging only — not a process transmitter.
Q: Which safety marks apply? A: CAT III 1000 V, CAT IV 600 V, IEC 61010-1, IEC 61010-2-032, IEC 61010-2-033, FCC ID T68-FBLE. Match the measurement location to the category.
Q: What should I send for a quote? A: Max current path needed, CAT needs, Fluke Connect yes/no, quantity, ship-to. Compatible with systems using Fluke 376 FC if you need a drop-in check — we do not claim authorized-dealer status.
