Safety Information

Please use the Agilent U1583A current clamp only as speciﬁed in this manual. Otherwise, the protection provided

may be impaired. Refer to the safety information below.

A WARNING identiﬁes conditions and actions that pose hazards to the user. A CAUTION identiﬁes conditions

and actions that may be damaging to the equipment under test.

WARNING

To avoid possible electric shock, personal injury or damage to this instrument, ensure that you use the adapter

safely, and follow these guidelines:

- Do not use the adapter if it is damaged. Inspect the case before you use the adapter. Look for cracks or missing

plastic. Pay particular attention to the insulation surrounding the connectors.

- Inspect the clamp jaw before each use. It shall not have cracks or missing parts, loose or weakened

components. Be sure there is insulation surrounding the jaw.

- Inspect output cable without exposing the metal to ensure insulation.

- Do not operate the adapter around explosive gas, vapor or dust.

- Do not exceed the rated voltage/ current as marked on the adapter.

- This current clamp is designed to be used on INSULATED CONDUCTORS up to 400 A, 600 V CAT III and on BARE

CONDUCTORS of up to 30 VAC rms or 60 VDC. DO NOT USE on BARE CONDUCTORS above 30 VAC rms or

60 VDC. Contact with these voltages will result in electric shock or arc explosion.

- Always keep your hand behind the ﬁnger guard of clamp jaw.

- When servicing the adapter, use only speciﬁed replacement parts.

- Use with caution when working above 30 VAC rms, 42 V peak or 60 VDC. Such voltage poses a shock hazard.

- Avoid working alone.

- Do not operate the adapter if the cover is removed or loosened.

CAUTION

To avoid possible damage to the current clamp or to the equipment under test, follow the guidelines below:

- Do not connect to BNC output or banana plug to any power sources.

- Use the proper terminals, function, and range for your measurements.

This current clamp is designed to be used on INSULATED CONDUCTORS up to 400 A,

600 V CAT III and on BARE CONDUCTORS of up to 30 VAC rms or 60 VDC. DO NOT USE

on BARE CONDUCTORS above 30 VAC rms or 60 VDC. Contact with these voltages may

result in electric shock or arc explosion.

Operation

AC current can be measured without removing the conductor from the circuit by following the procedures as

shown below:

1. Plug the cable with BNC connector to the BNC with dual banana plugs, and then plug into the V/COM

terminals on the multimeter. For oscilloscope, plug the BNC connector directly to oscilloscope.

2. Set the ACV measurement and range on multimeter you used.

3. Position the jaw to a single conductor and center it accordingly to the alignment marks.

4. Ensure that the arrow marked on the clamp jaw point towards the load for phase measurements or away

from the load (toward the source) for neutral measurements.

5. Observe the AC value on the multimeter or the waveform on the oscilloscope which is proportional to the

current.

6. Select a lower range on the clamp-on adapter and set the corresponding sensitivity (mV/A setting) on the

oscilloscope if required.

Calibration Equipment

The pre-calibration guidelines are shown as follows:

• Be sure you are a qualiﬁed person to perform the calibration

• The environment should be 23 °C ± 2 °C and the relative humidity (RH) shall be < 80%.

The test equipment requirements listed in the table below are required to perform the calibration and performance

veriﬁcation test procedures. Alternative equipment may be used as long as the accuracy is equivalent to or better

than the speciﬁcations listed.

Adjustment Procedures

AC 40 A range

1. Release RANGE button of U1583A current clamp to 40 A mode.

2. Connect the output BNC of U1583A to a BNC-to-dual banana converter plug and proceed to

connect it to the output of the V (HI) and COM (LO) terminals of the multimeter.

3. Set multimeter to AC 500.0 mV or 1000.0 mV.

4. Open the jaws of the current clamp and centrally place it around the 50 turns coil.

5. Set the calibrator output to 50 turns coil. Conﬁgure the calibrator to generate a current 20 A with

60 Hz frequency for adjustment of the current clamp.

6. Remove two Phillips screws on the back of the current clamp and proceed to adjust the VR1 until the

display on multimeter indicates AC 200 mV ± 0.2 mV. Refer to Figure 2 below for the position of

VR1.

Figure 2: U1583A Current Clamp Circuit Board Diagram

AC 400 A range

1. Lock the Range button of U1583A current clamp to 400 A mode.

2. Connect the output BNC of U1583A to a BNC-to-dual banana converter plug and proceed to

connect it to the output of the V (HI) and COM (LO) terminals of the multimeter.

3. Set multimeter to AC 500.0 mV or 1000.0 mV.

4. Open the jaws of the current clamp and centrally place it around the 50 turns coil.

5. Set the calibrator output to 50 turns coil. Conﬁgure the calibrator to generate a current 20 A with

60 Hz frequency for adjustment of the current clamp.

6. Remove two Phillips screws on the back of the current clamp and proceed to adjust the VR2 until the

display on multimeter indicates AC 200 mV ± 0.2 mV. Refer to Figure 2 for the position of VR2.

Remember to place the screws to its original position after performing the calibration

adjustments.

Maintenance

Repair or service not cover in this sheet should be performed only by qualiﬁed personnel.

To avoid electrical shock or damaged to the clamp-on adapter, do not get water inside the

case .

Cleaning

• Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasive or solvents.

• Open the jaws and wipe the metal of jaw with a lightly oiled cloth, and then wipe the oil with dry cloth.

Do not allow rust or corrosion to form on the metal ends of jaw.

Troubleshooting

If the current clamp does not perform properly, follow the steps below to identify the problem:

1. Inspect the mating surface of jaw for cleanliness. If any external material is present, the jaws may

not close properly and affects the result.

2. Verify that the function selection and range on the multimeter or oscilloscope as well as the range

adjusted on current clamp is correct.
