Introduction
XWWarning
Read "Safety Information" before you use the Meter.
The Fluke 381 is a handheld, battery-operated Clamp Meter (the Meter) that has a remote-display
module and detachable iFlex (Flexible Current Probe). The Remote Display can be removed from
the Meter body and read away from the measurement source. This lets the display be easily read
in difficult-measurement situations such as a hazardous environments, or very tight spaces. The
Flexible Current Probe makes it possible to measure higher current (up to 2500 A ac) and larger
cables that traditional jawed meters cannot measure.
