i3000s/i2000 Flex
AC Current Probe
Instruction Sheet
Introduction
The i3000s 24 Flex, i3000s 36 Flex, and i2000 Flex AC Current
Probes (hereafter referred to as “the Probe”) are used with
oscilloscopes, digital multimeters, recorders or data loggers. The
i3000s probes can be used to measure AC current up to 3000 A.
The i2000 can be used to measure AC current up to 2000 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 for i3000s models,
and 2 V AC for i2000) output that is proportional to the current
being measured. The Probes provide full-scale direct readings for
30 A, 300 A, and 3000 A when using the i3000s models, and 20
A, 200 A, and 2000 A when using the i2000.

•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:
•Never replace batteries with the flexible
measuring head installed on the conductor to
be tested or with the output connected to a
display device.
•Never operate the unit without the battery cover
installed.
The Probes require 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 (i3000s Models)
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, never connect or
disconnect the external power supply with the
flexible measuring head installed on the conductor
or with the output connected to a display device.

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.
XWWarning
To avoid electric shock or injury, the flexible current
probe is 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 probe 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 3000 A (i3000s models) or 2000 A (i2000)
current range and then reduce accordingly.
Battery Status
Battery status is indicated by an LED on the front of the probe.
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 Probe 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
electronics unit and measuring head. Make sure that the flexible
measuring head, connecting cable, and electronic enclosure are
dry before further use.
