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.
