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)
