3000A/6000A Flex 4
AC Current Probes
Instruction Sheet
Introduction
The 3000A/6000A current probe sets (the Probe) have been
designed for applications with Fluke 1735 and Fluke 1740
series products for accurate non-intrusive measurement of ac
currents. Using the latest technologies (integrated memory for
calibration data) provides current ranges from 0.8 A up to
6000 A in a frequency range of 40 Hz to 5 kHz.

WX Warning
The Probe may only be used and handled by
qualified personnel. To avoid electric shock or
personal injury, follow these precautions:
• Do not apply to or remove from hazardous
live conductors without taking additional
protective measures.
• High voltages and currents may be present in
adjacent circuits under test.
• Do not use the Probe if damaged. Always
connect to display device before it is installed
around the conductor.
• Use the Probe 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 Probe. 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.
• Equipment is considered to be used in 600 V
CAT IV and 1000 V CAT III environment.
CAT IV equipment is designed to be used at
the source of distribution system up to the
energy-meter within the installation. CAT III
equipment is designed to be used in
distribution panels, feeders and short branch
circuits, and the lighting system in large
buildings.
• Do not use Probe in damp or wet
environments or in locations that hazardous
gases exist.
Operating Instructions
1. Connect the Probe to the product current input jack.
2. Wear protective gloves or de-energize the circuit and
place the Probe around the conductor under test. Reenergize the circuit.
3. Observe and take measurements as required.
Positive output indicates that the current flow is in the
direction shown by the arrow on the Probe.
4. Wear protective gloves or de-energize the circuit
before removal of the Probe.
Cleaning
Clean the Probe periodically by wiping it with a damp cloth and
detergent. Do not use abrasive cleaners or solvents. Do not
immerse the Probe in liquids.
