Safety
Read this section carefully. It will familiarize you with the most important
safety instructions for handling the Product.
A Warning identifies hazardous conditions and procedures that are
dangerous to the user.
A Caution identifies conditions and procedures that can cause damage
to the Product or the equipment under test.
XW Warning
To prevent possible electrical shock, fire, or personal injury:
•Read all safety information before you use the Product.
•Carefully read all instructions.
•The Probe is only to be used and handled by qualified
personnel.
•Do not work alone.
•Always connect the Product to the test tool before it is installed
around a conductor.
•Use the Product only as specified, or the protection supplied by
the Product can be compromised.
•Comply with local and national safety codes. Use 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.
•Limit operation to the specified measurement category, voltage,
or current ratings.
•De-energize the circuit or wear personal protective equipment in
compliance with local requirements before you apply or remove
the Product.
•Do not touch voltages >30 V ac, 42 V ac peak, or 60 V dc.
•Do not use the Product around explosive gas, vapor, or in damp
or wet environments.
•Do not use the Product if it operates incorrectly.
•Do not use a current measurement as an indication that a circuit
is safe to touch. A voltage measurement is necessary to know if
a circuit is hazardous.
•Do not use the Product if it is damaged.
•Disable the Product if it is damaged.
•Do not use the Product if it has damaged insulation,
exposed metal, or if the wear indicator is visible. Do not use
if the flexible jaw wear indicator shows wear indicated by a
contrasting color on the inner insulation. Examine the
output lead for damaged insulation, exposed metal, or wear
indication.
•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 exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
•High voltages and currents can be present in adjacent
circuits under test.
•Do not use the Product above its rated frequency.
•Use the Product only on insulated conductors. Use caution
around bare conductors or bus bars. Do not touch the
conductor.

How to Use the i430-Flexi-TF-II
To use the i430-Flexi-TF-II, follow these instructions:
1. Connect the BNC connector of the i430-Flexi-TF-II to the input on
the Fluke 430 series Power Quality Analyzer.
2. Wear protective equipment or de-energize the circuit before you
connect the flexible probe around the conductor. See Figure 1.

Figure 1.
3. Re-energize the circuit if not energized.
4. Center the conductor perpendicularly inside the flexible probe area.
If this is not possible, an additional measurement error of
±2 % of reading can occur. See Electrical Specifications.
5. Avoid taking measurements close to other current-carrying
conductors if possible.
6. Make sure that the arrow marked on the probe coupling points
toward the correct orientation for correct phase display on the
instrument. See also the setup screen of the instrument.
7. Keep the probe coupling more than 2.5 cm (1 inch) away from the
conductor.
8. Observe the current value and waveform on the instrument display.

9. Observe the safety instructions when you connect and use the
i430-Flexi-TF-II.
10. Wear protective equipment or de-energize the circuit before you
disconnect the flexible probe.
WWarning
To prevent false and misleading readings on the instrument,
the setup for the current probe in the 430-series Power
Quality Analyzer must be the i430 Flex (on Fluke 430 series I)
or i430-Flexi-TF-II (on Fluke 430 series II).
Maintenance
Before each use to assure continued safety, inspect the Probe and its
latching system for any damage. Pay particular attention to the insulation
surrounding the Probe. A Probe under warranty will be promptly repaired
or replaced (at Fluke's discretion) and returned at no charge.
XW Warning
To prevent possible electrical shock, fire, or personal
injury:
•Remove the input signals before you clean the
Product.
•Have an approved technician repair the Product.
The flexible probe and its latching system require no special care.
For routine maintenance:
1. Ensure that no foreign body obstructs the latching mechanism.
2. Clean the Probe with a damp cloth and a mild detergent. Do not use
abrasives, solvents, or alcohol.
3. Do not immerse the Probe in liquids.
If the i430-Flexi-TF-II does not work
If the Probe does not perform properly, use the following steps to help
isolate the problem:
1. Inspect the coupling system for any damage.
If any foreign material is present, the coupling system will not close
properly and errors will result.
2. Inspect the cable between the flexible probe and the Power Quality
Analyzer for any damage.
3. Check if the i430-Flexi-TF-II is the selected current probe on the
Power Quality Analyzer (Clamp i430-Flexi-TF-II).
4. Verify that the function and range selection on the Power Quality
Analyzer is correct.
