AC Current Clamp
Instruction Sheet
Introducing the i3000s
The i3000s is a clamp-on AC Current Clamp for use with
oscilloscopes and multimeters with banana input using the supplied
Dual Banana to BNC Adapter. The clamp is optimized for
measurement on power distribution systems.
Unpacking
The following items should be included in your Current Clamp box:
• Current Clamp
•
Dual Banana to BNC Adapter (model PM9081/001)
•
Instruction Sheet (this paper)
Check the contents of the shipping box for completeness. If
something in the box has been damaged or missing, contact your
distributor or the nearest FLUKE sales or service office immediately.
Safety Information
Read First: Safety Information.
To ensure safe operation and service of the
current clamp, follow these instructions:
•
Read the operating instructions before use and follow all
safety instructions.
•
Use the Current Clamp only as specified in the operating
instructions, otherwise the clamp's safety features may
not protect you.
•
Adhere to local and national safety codes. Individual
protective equipment must be used to prevent shock and
arc blast injury where hazardous live conductors are
exposed.
•
Do not hold the Current Clamp anywhere beyond the
tactile barrier, see Figure 8.
• Before each use, inspect the Current Clamp. Look for
cracks or missing portions of the clamp housing or output
cable insulation. Also look for loose or weakened
components. Pay particular attention to the insulation
surrounding the jaws.
• Check the magnetic mating surfaces of the clamp jaws;
these should be free of dust, dirt, rust and other foreign
matter.
•
Never use the clamp on a circuit with voltages higher than
600 V CAT III.
−
CAT III equipment is designed to protect against
transients in equipment in fixed equipment
installations, such as distribution panels, feeders and
short branch circuits, and lighting systems in large
buildings.

• Use extreme caution when working around bare
conductors or bus bars. Contact with the conductor could
®
result in electric shock.
•
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.
