i6000s Flex
AC Current Probe
Instruction Sheet
Introduction
The i6000s 24 Flex and i6000s 36 Flex AC Current Probes (the
Probe) 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
A Warning identifies conditions and procedures that are
dangerous to the user. A Caution identifies conditions and
procedures that can cause damage to the Product or the
equipment under test.

Battery Installation
Warning
To prevent 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 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 personal 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 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, center 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 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 turn on the unit, move the switch from ‘Off’ position to the
required measurement 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
Warning
To prevent electric shock or personal injury:
• Do not use Probes if damaged.
• Always inspect the electronics unit, connecting
cable, and flexible measuring head for damage
before use.
• Keep the Probes clean and free of surface
contamination.
Use mild detergent 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.
