AC Current Clamp
Instruction Sheet
Introduction
The Fluke 3014-PR AC Current Clamp (the Clamp) is a compact
ac current clamp designed specifically for the Fluke 1750.
Designed to meet the most stringent demands in industry and
electrical contracting, it also meets the latest safety and
performance standards.

Safety Instructions
Please read this section carefully. It will familiarize you with the
most important safety instructions for handling the Clamp. In this
instruction sheet, a Warning identifies conditions and actions
that pose hazard(s) to the user. A Caution identifies conditions
and actions that may damage the test instruments.
WX Warning
The Clamp may only be used and handled by
qualified personnel. To avoid personal injury, follow
these precautions:
•To avoid electric shock, use caution during
installation; high voltages and currents may be
present in circuit under test.
•Do not use the Clamp if damaged. Always
connect to display device before it is installed
around the conductor.
•Use the Clamp only as specified in the
operating instructions; otherwise the safety
features may not protect you.
•Adhere to local and national safety codes.
Individual protective equipment must be used
to prevent the shock and arc blast injury where
hazardous live conductors are exposed.
•Before each use, inspect the Clamp. Look for
cracks or missing portions of the housing or
output cable insulation. Also look for loose or
weakened components.
•Use caution when working with voltages above
60 V dc, 30 V ac rms or 42 V ac peak. Such
voltages pose a shock hazard.
•Use of this equipment is designed to CAT III
standards. CAT III equipment is designed to
protect against the transients in the equipment
in fixed equipment installations, such as
distribution panels, feeders and short branch
circuits, and the lighting systems in large
buildings.
•Do not use the Clamp in wet environments or in
locations that hazardous gases exist.
•Do not hold the Current Clamp anywhere
beyond the tactile barrier, see Figure 1.

Operating Instructions
1. Connect the Clamp to the 1750 current input jack. Verify
that the 1750 has recognized that a current Clamp is
connected.
2. Place the Clamp around the conductor under test.
3. Observe and take measurements as required. Positive
output indicates that the current flow is in the direction
shown by the arrow on the Clamp.
Cleaning
Clean the Clamp periodically by wiping it with a damp cloth and
detergent. Do not use abrasive cleaners or solvents. Do not
immerse the Clamp in liquids.
