TECHNICAL DATA
Fluke 370 FC Series
True-rms Wireless AC/DC
Clamp Meters
The new Fluke 370 FC Series (376 FC, 375 FC and 374 FC)
offers advanced troubleshooting performance. The iFlex® flex-
ible 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)
