i6000s Flex
AC Current Probe
Instruction Sheet
Introduction
The i6000s 24 Flex and i6000s 36 Flex AC Current Probes
(hereafter referred to as “the Probes”) are used with
oscilloscopes, digital multimeters, recorders or data loggers. The
Probes can be used to measure AC current up to 6000 A. The
flexible measuring head allows current measurements on
conductors that are hard to reach or inaccessible using typical
clamp-on current probes.
The Probes provide a low-voltage (3 V ac) output that is
proportional to the current being measured. The Probes provide
full-scale direct readings for 60 A, 600 A, and 6000 A.

Safety Instructions
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 calibrator or the test
instruments.
WX Warning
To avoid electric shock or personal injury:
• If the Probes are used in a manner not
specified in these operating instructions,
protection provided by the Probes may be
impaired.
• Use the Probes only if qualified.
• Use caution during installation and use of the
Probes; high voltages and currents may be
present in circuit under test.
• Have maintenance performed by only qualified
service personnel.
• Protect the Probes against water and
humidity.
• Wear protective clothing and gloves as
required.
• Do not install this product on live conductors.
Always de-energize the circuit under test
before installing the flexible measuring head.
• Always inspect the electronics unit,
connecting cable, and flexible measuring head
for damage before using the Probe.
• Do not use the Probe if damaged.
• Always connect Probe to display device
before installing the flexible measuring head.
• Never change batteries while measurement
head is installed on conductor.
• Never connect or disconnect the external
power supply while the measurement head is
installed on a conductor.
• Use only the provided original or specified
accessories.
• Adhere to local and national safety codes.
Individual protective equipment must be used
to prevent shock and arc blast injury where
hazardous live conductors are exposed.
• CAT III equipment is designed to protect
against the transients in the equipment in
fixed equipment installations, such as
distribution panels, feeders and short branch
circuits, and the lighting systems in large
buildings.

Battery Installation
XWWarning
To avoid electric shock or personal injury:
• Remove Probe from energized circuits before
opening battery door.
• Never operate the unit without the battery cover
installed.
The Probe requires two AA/MN1500/LR6 alkaline batteries for
operation. The battery compartment is accessed from the rear
end of the electronic enclosure.
The batteries must be replaced when the LED is lit continuously
or when it fails to light up. Ensure that the Probe is away from
any current carrying conductor and also that the output is
disconnected from other equipment.
To install the battery:
1. Use a coin or a similar tool to turn the battery lock (¼
turn) until the dot aligns with the unlock symbol.
2. Remove the battery cover.
3. Install the batteries ensuring that correct polarity is
observed.
4. Replace the battery cover and turn the battery lock until
the dot aligns with the lock symbol.
External Power Supply
An optional Class II external power supply is available from
Fluke. The power supply is designed to ensure that the Probe
continues to meet its specified safety standards. The usage of a
power supply from another vendor is not recommended.
XWWarning
To avoid electric shock or injury, remove Probe and
all other connections from energized circuits before
connecting external power supply to the instrument.
Measuring Current
XWWarning
• To avoid electric shock or injury, read Safety
Instructions before operating this product
• Ensure that the conductor to be tested is de-
energized
To measure current:
1. Connect the output of the electronics to the input of an
oscilloscope or other data recording device.
i6000s English Instruction Sheet

XWWarning
To avoid electric shock or injury, the flexible current
Probes are not for use on conductors with a
potential of over 600 V.
2. Wrap the flexible measuring head around the conductor
to be tested in a close coupling manner.
3. Energize the circuit under test.
4. For most accurate measurement, centre the flexible
head around the conductor.
5. Locate coupling away from the nearby conductors.
WX Warning
To avoid electric shock or injury:
• Do not use the flexible current Probes to
measure bare conductors unless wearing
protective clothing suitable for high voltage
work.
• Always use appropriate equipment for personal
protection. When installed on bare
conductors/busbars, the product must be within
a suitable enclosure.

Operation
To activate the unit, move the switch from ‘Off’ position to the
required measuring range. If the value of current being measured
is unknown, select the 6000 A current range and then reduce
accordingly.

Battery Status
Battery status is indicated by an LED on the front of the Probes.
This LED will flash one time when the unit is activated. The
length of time the LED is lit will increase as battery life
decreases. Momentary lighting of LED indicates batteries are
good. Continuous lighting of LED indicates low battery and
requires replacement at the earliest. No lighting of LED indicates
batteries are dead and require replacement immediately.
Maintenance
WX Warning
To avoid electric shock or injury:
• Do not use Probes if damaged.
• Always inspect the electronics unit, connecting
cable, and flexible measuring head for damage
before use.
• To avoid electric shock, keep the Probes clean
and free of surface contamination.
Use Isopropyl alcohol to clean the control unit and measuring
head. Make sure that the flexible measuring head, connecting
cable, and electronic enclosure are dry before further use.
