Introducing the i2000flex
The i2000flex is a flexible AC current probe for use with
oscilloscopes and multimeters. The supplied Dual Banana to BNC
Adapter can be used for connection to instruments with banana
inputs. The i2000flex is optimized for current measurement on thick
and hard to reach conductors.

• Instruction Sheet (this paper)
Check the contents of the shipping box for completeness. If
something in the box has been damaged or missing, contact your
distributor or the nearest FLUKE sales or service office
immediately.
Using the i2000flex Safely
Warning
To prevent electric shock, fire, and personal injury,
carefully read all safety information before
attempting to operate the Current Probe and follow
these procedures.
• Before each use, inspect the Current Probe and its latching
system for any damage. Pay particular attention to the
insulation surrounding the flexible measuring head.
• Do not use the Current Probe if it is damaged.
• Do not use the Current Probe on circuits rated higher than
600V in Installation Category III (See "Specifications",
subsection “SAFETY”.)
• Do not use the Current Probe to measure bare conductors
carrying a voltage from 30V up to 600V unless you are
wearing protective clothing suitable for high-voltage work.
Always use appropriate equipment for personal protection.
• Do not expose the i2000flex unit to water.
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 current probe.

Instrument Compatibility
The i2000flex can be used with any Fluke ScopeMeter test tool,
Power Quality Analyzer, Oscilloscope, or Multimeter that has the
following features:
• BNC input connector. The Dual Banana to BNC Adapter
included in the package, can be used to connect to standard
inputs on multimeters. For the 120 series ScopeMeters and
the Fluke 43 Power Quality Analyzer, use the BB120 Shielded
Banana to BNC Adapter (optional accessory).
• Input accuracy of 1% or better to take full advantage of the
accuracy of the Current Probe.
• Input impedance of greater than or equal to 1 kΩ, and for full
bandwidth and accuracy, a maximum input capacity of 100 pF.
• A passband of more than four times the frequency of the
waveform to be measured.
Using the i2000flex
To use the i2000flex, follow these instructions:
1. Connect the BNC connector of the i2000flex to the desired
input on the measuring instrument. When you are using a
multimeter, use the Dual Banana to BNC Adapter
(PM9081/001) to connect the i2000flex to the input. (See
Figure 5.)
2. On the i2000flex unit, select the least sensitive range (set the
slide switch to position ‘1 mV/A’).
3. Select the corresponding sensitivity (.. mV/A) on your
ScopeMeter test tool or oscilloscope. If you are using a
multimeter, select an appropriate AC voltage range.
Figure 4. Connecting the flexible probe around the conductor.
4. Connect the flexible probe around the conductor (See
Figure 4.)
5. Make sure that the arrow marked on the probe coupling points
toward the correct orientation for correct phase display on the
oscilloscope. (See Figure 6.)
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.
8. If desired, select the lower range on the i2000flex unit and set
the corresponding sensitivity on the measurement instrument.
If the i2000flex is used with a multimeter, the actual current value
can be calculated from the displayed AC voltage value.

Warning
If the sensitivity setting (mV/A) of the ScopeMeter
test tool or oscilloscope does not correspond with
the setting of the Current Probe, the ScopeMeter test
tool or oscilloscope may display a much lower
current than the actual value. This may result in a
false and misleading reading.

Measurement Considerations
Though the i2000flex is intended for measurements on hard to
reach conductors, observe the following guidelines to approach the
maximum measurement accuracy of ±1% of full scale as far as
possible:
• Center the conductor perpendicularly inside the flexible probe
area. If this is not possible, an additional measurement error
of ±2% of full scale can occur.
• Avoid taking measurements close to other current-carrying
conductors if possible. An external field of maximum 40 A/m
can cause an additional measurement error of 1% of full
scale.
The probe coupling must be at least 2.5 cm (1 inch) away from the
conductor to which the probe is attached, to meet specified
measurement accuracies.
Also see under “Additional errors” in the section “Specifications”.
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 i2000flex 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 i2000flex unit with a damp cloth and a mild
detergent. Do not use abrasives, solvents, or alcohol.
• Remove the battery when storing the i2000flex for a long
period of time.
Replacing the Battery
Replace the 9V battery when the ‘BATTERY LOW’ LED on the
i2000flex unit flashes when the power is switched on (a range is
selected.)
• Remove the flexible current probe, from any circuit to
be measured.
• Set the unit switch to OFF.
• Disconnect the unit from the measurement
instrument.
Note:
The i2000flex unit contains an alkaline battery. Do not
dispose of this battery with other solid waste. Used
batteries should be disposed of by a qualified recycler
or hazardous materials handler. Contact your
authorized FLUKE Service Center for recycling
information.
Follow the steps 1 to 5 depicted in the following figure to replace
the battery.
Figure 7. Replacing the battery
If your i2000flex does not work
If the i2000flex 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 cables between the flexible probe and the unit and
between the unit and the measurement instrument for any
damage.
• Check if the slide switch on the unit is set to the appropriate
current range, matching with the range (or sensitivity) of the
measurement instrument.
• Check if the “POWER ON” LED on the unit is flashing, and the
“BATTERY LOW” LED is not flashing. Otherwise replace the
battery. Also replace the battery if both LEDs stay off.
• Verify that the function selection on the measurement
instrument is correct.
• If your measurement instrument has a sensitivity setting for a
current probe, select the correct setting (1 mV/A or 10 mV/A).
• If you use a multimeter, preferably select the 2V ac range for
full range measurements with best accuracy results.
