FLUKE i400s AC Current Clamp (400 A)

Safety Information

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 live conductors are 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 clamp on a circuit with voltages higher than 1000 V CAT III or 600 V CAT IV.
  • 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.
  • CAT IV equipment is designed to protect against transients from the primary supply level, such as an electricity meter or an overhead or underground utility service.
• 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. Such voltages pose a shock hazard.
