Fluke i5s Operating Manual

i5s AC Current Clamp

Instruction Sheet

Introduction

The i5s (hereafter called the “Current Clamp”) is compatible with any instrument that can accept a standard BNC connector and is capable of ac millivolt measurements; also be used with digital multimeters using a BNC-to-dual banana pl Clamp produces an output of 400 mV ac per 1 A ac input level.

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 Clamp only as specified in the operating instructions, otherwise the

clamp’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 exposed.

• Do not hold the Current Clamp anywhere beyond the tactile barrier, see Figure 1.

• Before each use, inspect the Current Clamp. Look for cracks or missing portions of the

clamp housing or output cable insulation. Also look for loose or weakened components. Pay particular attention to the insulation surrounding the jaws.

• Never use the Current Clamp 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.

• The Clamp is designed for use on insulated conductors only. Use extreme caution when

working around bare conductors or bus bars. Contact with the conductor could result in electric shock.

• Use caution when working with voltages above

60 V dc or 30 V ac rms. Such voltages pose a shock hazard.

Instrument Compatibility

The Current Clamp is compatible with any Fluke Multimeter or any other current measurement device that has the following features:

• BNC or Banana inputs

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

• Input impedance of > 1 M Ω in parallel with up to 47 pF

Note

Current input impedance on the Fluke 430 Series Three-Phase Power Quality Analyzer is < 1 MΩ, but it has a special calibration setting for the i5s to achieve full accuracy.

Measurement Considerations

• Center the conductor inside the Current Clamp jaw.

• Make sure the Current Clamp is perpendicular to the conductor.

• For optimal reading, make sure the conductor is centered in the jaws of the Current

Clamp.

Observe the following guidelines when making measurements:

• Avoid taking measurements close to other current-carrying conductors.

Operation

To use the Current Clamp, refer to “Measurement Considerations” and Figure 1:

1. If necessary, add a dual banana plug to BNC adapter to the i5s B

2. Connect the clamp cable to the instrument. If using an adapter, use the common and volts inputs of the meter and switch it on.

3. Make sure the measurement instrument is set to the proper range.

4. Make sure the arrows on each side of the Current Clamp face towards the load of the circuit.

5. Open the Current Clamp jaw by pushing the release button toward the jaw until the latch has cleared the barrier, then press down to open the jaw.

6. Connect the Current Clamp jaws around the insulated conductor to be measured and release the button. Ensure that the release button has returned to the original position to resume the circuit testing.

To avoid shock or personal injury, keep fingers behind the tactile barrier, see Figure 1.

Maintenance

To avoid possible electric shock or personal injury:

• Before each use, inspect the Current Clamp. Look for cracks or missing portions of the

clamp housing and output cable insulating cover and for loose or weakened components. Pay particular attention to the insulation surrounding the clamp jaws.

• Do not use a damaged Current Clamp. If a clamp is damaged, tape it shut to prevent

unintended operation. A damaged clamp under warranty will be promptly repaired or replaced (at Fluke’s discretion) and returned at no extra charge.

If the Current Clamp does not work or perform properly, use the following steps to help isolate the problem:

1. Inspect the jaw mating surface for cleanliness. If an not close properly and measurement errors will result.

2. Verify that the function selection and range on the Multimeter are correct and adjusted to the sensitivity of the Current Clamp.

XW Warning

Cleaning

Periodically wipe the case with a damp cloth and mild detergent.

To avoid damaging the Current Clamp, do not use abrasives or solvents to clean the clamp.

Open the jaws and wipe the magnetic pole pieces with a lightly oiled cloth. Do not allow rust or corrosion to form on the magnetic core ends.
