Calibration 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.
XW Read First: Safety Information
• Never use the Current 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.
