FLUKE i3000s Flex AC Current Probe Instructions

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 clampon 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.

Operating Instructions

Battery Installation

Warning

To prevent electrical 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:

Use a coin or a similar tool to turn the battery lock (¼ turn) until the dot aligns with the unlock symbol.
Remove the battery cover.
Install the batteries ensuring that correct polarity is observed.
Replace the battery cover and turn the battery lock until the dot aligns with the lock symbol.

Measuring Current

Warning

To prevent electrical shock or personal injury:

Read Safety Instructions before operating this product.
Ensure that the conductor to be tested is de-energized.

To measure current:

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, do not use the flexible current probe on conductors with a potential of over 600 V. Wrap the flexible measuring head around the conductor to be tested in a close coupling manner.
Energize the circuit under test.
For most accurate measurement, center the flexible head around the conductor.
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 the “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 the 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.
