Frequently Asked Questions - i6000s Flex FLUKE

How do I install batteries in the Fluke i6000s Flex?

Turn the battery lock on the rear of the electronics enclosure with a coin until the dot aligns with the unlock symbol. Remove the cover, insert two AA IEC LR6 alkaline batteries with correct polarity, replace the cover, and turn the lock to the lock position.

How do I measure current with the i6000s Flex?

First, ensure the conductor is de-energized. Connect the output cable to an oscilloscope or data recorder. Wrap the flexible measuring head around the conductor and close the coupling. Then energize the circuit. Center the head for best accuracy and keep the coupling away from nearby conductors.

What are the current ranges of the i6000s Flex?

The probe has three selectable ranges: 60 A, 600 A, and 6000 A AC rms. Use the rotary switch to select the appropriate range.

What is the output sensitivity for each range?

Output sensitivity is 50 mV/A on the 60 A range, 5 mV/A on the 600 A range, and 0.5 mV/A on the 6000 A range (AC coupled).

What is the accuracy of the i6000s Flex?

Accuracy is ±1% of range from 45 Hz to 65 Hz at 25 °C. Linearity is ±0.2% of reading from 10% to 100% of range.

What is the frequency range of the probe?

The frequency range is 10 Hz to 50 kHz (-3 dB typical). Phase error is <±1° from 45 Hz to 65 Hz and ±10° at 20 kHz.

What safety precautions should I take when using the i6000s Flex?

Always de-energize the circuit before installing the flexible head. Do not use on live conductors above 600 V. Wear appropriate protective equipment. Inspect the probe for damage before use. Never change batteries with the head installed on a conductor.

How do I clean the i6000s Flex?

Use a mild detergent to clean the control unit and measuring head. Ensure all parts are dry before further use. Do not use abrasive cleaners or solvents.

What does the LED indicator mean?

The LED flashes briefly when the unit is turned on. A momentary flash indicates good batteries. Continuous light indicates low batteries requiring replacement. No light means batteries are dead and must be replaced immediately.

What is included in the box with the i6000s Flex?

The probe includes the measuring head, electronics enclosure, output cable with BNC connector, a 4 mm safety plug adapter, and two AA batteries. A user manual is available for download. Additional accessories may be ordered separately.

USER MANUAL i6000s Flex FLUKE

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.

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 ( 14 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 all safety information before you use the 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.

1. Wrap the flexible measuring head around the conductor to be tested in a close coupling manner.
2. Energize the circuit under test.
3. For most accurate measurement, center the flexible head around the conductor.
4. 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 the Product if it is altered or 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.
