TECHNICAL DATA
Fluke 370 FC Series True-rms
Wireless AC/DC Clamp Meters
The Fluke 370 FC Series (376 FC, 375 FC and 374
FC) offers advanced troubleshooting performance.
The iFlex
™
flexible current probe allows easy connections to wires
in tight spaces. In addition, all three clamps are now part of the
Fluke Connect™ family of wireless test tools. Now you can:
• Log and trend measurements to pinpoint intermittent faults
• Transmit results wirelessly via Fluke Connect Measurements app
• Create and send reports right from the field
• Capture measurements outside the arc flash zone with Bluetooth
connectivity to your Apple or Android devices
Product highlights
• Connect your meter to your smartphone using Fluke Connect
Measurements app to increase the troubleshooting power of
your clamp
• Read measurements on your phone at a safe distance, wearing
less PPE while your meter takes all the risks
• Record results directly to your phone and the Fluke Cloud™
• Capture intermittent faults while performing other tasks using the
logging capabilities of the Fluke 376 FC and 375 FC
• Create and share reports from the field via email, or converse in
real time with ShareLive™ video calls
• iFlex flexible current probe expands the measurement range to
2500 A ac; provides access to large conductors in tight spaces
(included with 376 FC; compatible with 375 FC and 374 FC)
• TPAK magnetic hanging strap (included with 376 FC; compatible
with 375 FC and 374 FC) allows you to conveniently hang the
meter while using the probes
• Integrated VFD low pass filter (Fluke 376 FC and 375 FC) for
accurate motor drive measurements
• Proprietary in-rush measurement technology to filter out
noise and capture motor starting current exactly as the circuit
protection sees it
• CAT IV 600 V, CAT III 1000 V safety rating
• Three-year warranty
• Soft carrying case
