3310-PR/3312-PR
Flex Current Probe
Instruction Sheet
Introduction
The Fluke 3310-PR and 3312-PR Current Probes (“the Probe”)
are ac current probes utilizing the Rogowski principle. They can
be used with the Fluke 1750 to measure current from very low
frequencies up to 15 kHz. The flexible and lightweight measuring
head allows quick and easy installation in hard to reach areas
and with large conductors.
The Probes are designed for use with the Fluke 1750 Power
Recorder.

WX Warning
The Probe may only be used and handled by
qualified personnel. To avoid electric shock or
personal injury, follow these precautions:
• De-energize circuit during installation and
removal of probe.
• 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.
