•
De-energize the installation on which current will be measured
or adopt safe operating procedures
during application and
removal of the current probe.
•
Use extreme caution when working around bare
conductors or
bus bars.
•
Do not use the Current Probe to measure bare conductors
carrying a voltage from 30 V up to 1000 V unless you are
wearing protective clothing suitable for high-voltage work.
Contact with the conductor could result in electric shock. Always
use appropriate
equipment for personal protection.
•
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.

Instrument Compatibility
The i430flex can only be used with the Fluke 430 series Power
Quality Analyzers.
Using the i430flex
To use the i430flex, follow these instructions:
1.
Connect the BNC connector of the i430flex to the desired input
on the Fluke 430 series Power Quality Analyzer.
Figure 1. Connecting the flexible probe around the conductor.
2.
Connect the flexible probe around the conductor (See
Figure 1.)
3.
Center the conductor perpendicularly inside the flexible probe
area. If this is not possible, an additional measurement error of
±2% of reading can occur.
4.
Avoid taking measurements close to other current-carrying
conductors if possible.
5.
Make sure that the arrow marked on the probe coupling points
toward the correct orientation for correct phase display on the
instrument.
6.
Keep the probe coupling more than 2.5 cm (1 inch) away from
the conductor.
7.
Observe the current value and waveform on the instrument’s
display.
Warning
If the selected current probe of the Fluke 430 series
Power Quality Analyzer is not the i430flex, the
Fluke 430 will display false and misleading readings.
Maintenance
Before each use, assure continued safety by inspecting the flexible
probe and its latching system for any damage. Pay particular
attention to the insulation surrounding the flexible probe. An i430flex
under warranty will be promptly repaired or replaced (at Fluke's
discretion) and returned at no charge.
Cleaning and Storage
•
The flexible probe and its latching system require no special
care. Ensure that no foreign body obstructs the latching
mechanism.
•
Clean the i430flex with a damp cloth and a mild detergent. Do
not use abrasives, solvents, or alcohol.
If your i430flex does not work
If the i430flex does not perform properly, use the following steps to
help isolate the problem:
•
Inspect the coupling system for any damage. If any foreign
material is present, the coupling system will not close properly
and errors will result.
•
Inspect the cable between the flexible probe and the Power
Quality Analyzer for any damage.
•
Check if the i430flex is the selected current probe on the
Power Quality Analyzer (Clamp i430flex).
•
Verify that the function and range selection on the Power
Quality Analyzer is correct.
