i3000s/i2000 Flex
AC Current Probe
Instruction Sheet
Introduction
The i3000s 24 Flex, i3000s 36 Flex, and i2000 Flex AC Current
Probes (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.

Battery Installation
Warning
To prevent 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 IEC 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.
Measuring Current
Warning
To prevent 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.
Warning
To prevent electric shock or personal 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.
 Warning
To prevent electric shock or personal 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
 Warning
To prevent electric shock or personal 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 mild detergent 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.
