Keysight 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 Keysight digital multimeter (DMM) and Keysight oscilloscope. A BNC-to-banana plug adapter is required when connecting the current clamp to a multimeter. For oscilloscope, connect the current clamp directly to the input terminal with the BNC connector.

Safety Information Please use the Keysight U1583B current clamp only as specified in this manual. Otherwise, the protection provided may be impaired. 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. To avoid possible electric shock, personal injury or damage to this instrument, ensure that you use the current clamp safely, and refer to the guidelines below. Range button in release mode. AC : Alternating Current Range ~ 400 A, Output ~ 1 mV/A Caution, risk of danger (Refer to the DC : Direct Current users and service guide for details) Maximum allowable current 400A MAX Ground measurement is 400 A Category III 600V over-voltage CAT III 600V Double Insulation protection Caution, risk of electric shock (Refer Range button in lock mode. to the users and service guide for Range ~ 40 A, Output ~ 10 mV/A detail) To be applied around or removed from un-insulated hazardous live conductors- Do not use the current clamp if it is damaged. Inspect the case before using the current clamp. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors. - Inspect the clamp jaw before each use. No cracks, missing, loosen or weaken parts shall be observed. Ensure there is insulation surrounding the jaw. - Inspect the cable without exposing the metal to ensure insulation. - Do not operate the current clamp around explosive gas, vapor, or dust. - Do not exceed the rated voltage/current as marked on the current clamp. Use with extreme caution when working around bare conductors. Accidental contact with the exposed conductors could result in electric shock. - Always keep your hand behind the finger guard of the clamp jaw. - When servicing the current clamp, use only specified replacement parts. - Use with caution when working above 30 V ac rms, 42 V peak, or 60 V dc. These voltages pose a shock hazard. - Do not operate the current clamp if the cover is removed or loosened. - Use individual protective equipment if working in installations with accessible hazardous live parts. - If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired - Do not operate the current clamp around flammable gases or fumes, vapor, or wet environments. - Do not connect to the BNC output or the banana plug to any power sources. - Use proper terminals, function, and range for your measurements.
