Introducing the i2000flex

The i2000flex is a flexible AC current probe for use with oscilloscopes and multimeters. The supplied Dual Banana to BNC Adapter can be used for connection to instruments with banana inputs. The i2000flex is optimized for current measurement on thick and hard to reach conductors.

Unpacking

The following items should be included in the package:

• i2000flex Current Probe

• Dual Banana to BNC Adapter (model PM9081/001)

Check the contents of the shipping box for completeness. If something in the box has been damaged or missing, contact your distributor or the nearest FLUKE sales or service office immediately.

Safety Information

Read First: Safety Information

To ensure safe operation and service of the current clamp, follow these instructions:

• Read the operating instructions before use and follow all safety instructions.

• Use the Current Probe only as specified in the operating instructions; otherwise the 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.

• Before each use, inspect the Current Probe and its latching system for any damage. Pay particular attention to the insulation surrounding the flexible measuring head. Look for cracks or missing portions of the probe housing or output cable insulation. Also look for loose or weakened components.

• Do not use a probe that is cracked, damaged, or has a defective cable.

• Never use the probe on a circuit with voltages higher than 600 V CAT III.

− CAT III equipment is designed to protect against transients

in equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and lighting systems in large buildings.

• De-energize the installation on which current will be measured or adopt safe operating procedures during application and removal of the current probe.

• Use extreme caution when working around bare bus bars.

• Do not use the Current Probe to measure bare conductors carrying a voltage from 30V up to 600V unless you are wearing protective clothing suitable for high-voltage work. Contact with the conductor could result in electric shock. Always use appropriate

• Use caution when working with voltages above 60 V dc, 30 V ac rms or 42 V ac peak. Such voltages pose a shock hazard.

Instrument Compatibility

The i2000flex can be used with any Fluke ScopeMeter test tool, Power Quality Analyzer, Oscilloscope, or Multimeter that has the following features:

• BNC input connector. The Dual Banana to BNC Adapter included in the package, can be used to connect to standard inputs on multimeters. For the 120 series ScopeMeters and the Fluke 43 Power Quality Analyzer, use the BB120 Shielded Banana to BNC Adapter (optional accessory).

• Input accuracy of 1% or better to take full advantage of the accuracy of the Current Probe.

• Input impedance of greater than or equal to 1 kΩ, and for full bandwidth and accuracy, a maximum input capacity of 100 pF.

• A passband of more than four times the frequency of the waveform to be measured.

Using the i2000flex

To use the i2000flex, follow these instructions:

1. Connect the BNC connector of the i2000flex to the desired input on the measuring instrument. When you are using a multimeter, use the Dual Banana to BNC Adapter (PM9081/001) to connect the i2000flex to the input. (See Figure 5.)

2. On the i2000flex unit, select the least sensitive range (set the slide switch to position ‘1 mV/A’).

3. Select the corresponding sensitivity (.. mV/A) on your ScopeMeter test tool or oscilloscope. If you are using a multimeter, select an appropriate AC voltage range.

4. Connect the flexible probe around the conductor (See Figure 4.)

5. Make sure that the arrow marked on the probe coupling points

toward the correct orientation for correct phase display on the oscilloscope. (See Figure 6.)

6. Keep the probe coupling more than 2.5 cm (1 inch) away from

the conductor.

7. Observe the current value and waveform on the instrument’s

display.

8. If desired, select the lower range on the i2000flex unit and set

the corresponding sensitivity on the measurement instrument.

If the i2000flex is used with a multimeter, the actual current value can be calculated from the displayed AC voltage value.

Maintenance

• Before each use, assure continued safety by inspecting the flexible probe and its latching system for any damage. Pay

particular attention to the insulation surrounding the flexible probe. An i2000flex under warranty will be promptly repaired or replaced (at Fluke's discretion) and returned at no charge.

Cleaning and Storage

• The flexible probe and its latching system require no special care. Ensure that no foreign body obstructs the latching mechanism.

• Clean the i2000flex unit with a damp cloth and a mild detergent. Do not use abrasives, solvents, or alcohol.

• Remove the battery when storing the i2000flex for a long period of time.

Replacing the Battery

Replace the 9V battery when the ‘BATTERY LOW’ LED on the i2000flex unit flashes when the power is switched on (a range is selected.)

Follow the steps 1 to 5 depicted in the following figure to replace the battery.

• To avoid false readings which could cause injury, replace battery as soon as the red Low Battery Indicator flashes.

• Remove the flexible current probe, from any circuit to be measured.

• Set the unit switch to OFF.

• Disconnect the unit from the measurement

instrument.

The i2000flex unit contains an alkaline battery. Do not dispose of this battery with other solid waste. Used batteries should be disposed of by a qualified recycler or hazardous materials handler. Contact your authorized FLUKE Service Center for recycling information.

Note:

Figure 5. Measurement Setup

Warning

If the sensitivity setting (mV/A) of the ScopeMeter test tool or oscilloscope does not correspond with the setting of the Current Probe, the ScopeMeter test tool or oscilloscope may display a much lower current than the actual value. This may result in a false and misleading reading.

Measurement Considerations

Though the i2000flex is intended for measurements on hard to reach conductors, observe the following guidelines to approach the maximum measurement accuracy of ±1% of full scale as far as possible:

• Center the conductor perpendicularly inside the flexible probe area. If this is not possible, an additional measurement error of ±2% of full scale can occur.

• Avoid taking measurements close to other current-carrying conductors if possible. An external field of maximum 40 A/m can cause an additional measurement error of 1% of full scale.

The probe coupling must be at least 2.5 cm (1 inch) away from the conductor to which the probe is attached, to meet specified measurement accuracies.

Also see under “Additional errors” in the section “Specifications”.

Figure 7. Replacing the battery

If your i2000flex does not work

If the i2000flex does not perform properly, use the following steps to help isolate the problem:

• Inspect the coupling system for any damage. If any foreign material is present, the coupling system will not close properly and errors will result.

• Inspect the cables between the flexible probe and the unit and between the unit and the measurement instrument for any damage.

• Check if the slide switch on the unit is set to the appropriate current range, matching with the range (or sensitivity) of the measurement instrument.

• Check if the “POWER ON” LED on the unit is flashing, and the “BATTERY LOW” LED is not flashing. Otherwise replace the battery. Also replace the battery if both LEDs stay off.

• Verify that the function selection on the measurement instrument is correct.

• If your measurement instrument has a sensitivity setting for a current probe, select the correct setting (1 mV/A or 10 mV/A).

• If you use a multimeter, preferably select the 2V ac range for full range measurements with best accuracy results.
