Agilent U1583B User guide

Agilent U1583B Current Clamp

Operating Instructions

The U1583B current clamp is a dual range 40 A and 400 A clamp-on AC current clamp. This U1583B current
clamp is designed for Agilent handheld digital multimeter (DMM) and Agilent handheld oscilloscope. The
BNC-to-banana plug is required to connect the current clamp with DMM. While for handheld oscilloscope,
it needs to use with BNC connector.

Safety Information

Please use the Agilent U1583A current clamp only as specifi ed in this manual. Otherwise, the protection
provided may be impaired. A WARNING identifi es conditions and actions that pose hazards to the user. A
CAUTION identifi es conditions and actions that may be damaging to the equipment under test. To avoid
possible electric shock, personal injury or damage to this instrument, ensure that you use the adapter
safely, and refer to the guidelines below.

400A MAX

CAT III 600V

AC - Alternating Current

Caution, risk of danger (Refer to the
user’s and service guide for details)

Maximum allowable current
measurement is 400 A

Category III 600V over-voltage protection Double Insulation

Range button in lock mode.
Range ~ 40 A, Output ~ 10 mV/A

To be applied around or removed from
un-insulated hazardous live conductors

- 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.

Range button in release mode.
Range ~ 400 A, Output ~ 1 mV/A

DC - Direct Current

Ground

Caution, risk of electric shock (Refer to
the user’s and service guide for detail)

- 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.

- Use with extreme caution when working around bare conductors or bus bars. It could
results in electric shock if have accidentally contact to the conductors.

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

- When servicing the adapter, use only specifi ed replacement parts.

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

- Avoid working alone.

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

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

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