Thin Flex Current Probe

Instruction Sheet

Introduction

The 3210-PR-TF Flex Thin Flex Current Probe (the Probe or Product) is
an ac current probe utilizing the Rogowski principle. The Probe is
designed for use with the Fluke 1750 Power Recorder and measures
current from very low frequencies up to the 50
power supply. The flexible and lightweight measuring head allows quick
and easy installation in hard to reach areas and around large conductors.

Safety Instructions

Please read this section carefully. It will familiarize you with the most
important safety instructions for handling the Probe. 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 Probe or the test equipment.

 Warning

To prevent possible electrical shock, fire, or personal injury:

• The Probe is to only be used and handled by qualified

personnel.

• Always connect to display device before it is installed

around the conductor.

• Use the Product only as specified, or the protection

supplied by the Product can be compromised.

• High voltages and currents can be in adjacent circuits

under test.

• Before each use, examine the Product. Look for cracks or

missing pieces of the clamp housing or output cable
insulation. Also look for loose or weakened components.
Carefully examine the insulation around the jaws.

• Do not use if the output cable wear indicator shows

(contrasting color inner insulation).

• Do not use and disable the Product if it is damaged.

• Comply with local and national safety codes. Use

Fluke-Direct

personal protective equipment (approved rubber gloves,
face protection, and flame-resistant clothes) to prevent
shock and arc blast injury where hazardous live
conductors are exposed.

• Do not work alone.

• Limit operation to the specified measurement category,

voltage, or amperage ratings.

• De-energize the circuit or wear personal protective

equipment in compliance with local requirements before
you apply or remove the Flexible Current Probe.

• Do not touch voltages > 30 V ac rms, 42 V ac peak, or

60 V dc.

• Equipment is to be used in 600 V CAT IV and 1000 V

CAT III environments.

• Do not use the Product around explosive gas, vapor, or in

damp or wet environments.

Operating Instructions

1. Connect the Probe to the 1750 via the 1750 current input jack.

2. Wear protective equipment or de-energize the circuit and place
the Probe around the conductor under test. To lock the coil,
see Figure 1.

3. Re-energize the circuit.

4. Observe and take measurements as required. Positive output
indicates that the current flow is in the direction shown by the
arrow on the Probe.

5. Wear protective gloves or de-energize the circuit before
removal of the Probe.

Maintenance

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.
