Introduction
The Fluke 377, 377 FC, 378, and 378 FC Current Clamp (the
Clamp or Product) provides:
•
display with two simultaneous measurements (current and
voltage)
•
grounding with a single lead
•
live measurements with no circuit downtime
•
non-contact voltage measurement with Power Quality
Indicator
•
wireless connectivity to smartphone for work-orders and
reporting integration with Fluke Connect™ app
The Clamp measures true-rms ac current and voltage, dc current
and voltage, inrush current, resistance, capacitance, frequency,
and dc millivolts.
The included iFlex (detachable, flexible current-probe) expands
the measurement range to 2500 A ac. The iFlex allows
measurements of awkward sized conductors and improved wire
access.
The illustrations in this manual show the 378 FC.
