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.

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:

• Use the Probes only if qualified.

• Use caution during installation and use of

the Probe; high voltages and currents may
be present in circuit under test.

• Have maintenance performed by only

qualified service personnel.

• Protect the probe 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.

• Use the Current Probe only as specified in

the operating instructions; otherwise the
current probe’s safety features may not
protect you.

• 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.
