Fluke i3000s Flex Series, i2000 Flex, i3000s 24 Flex, i3000s 36 Flex Instruction Sheet

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

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.

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 de­energized
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.
