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

Page 7

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.

Ieb0001.eps

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.
