Description
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.
