Page 4: Safety Information
1.3 Safety information Symbols Used The following table lists the International Electrical Symbols. Some or all of these symbols may be used on the instrument or in this manual. Symbol Description AC (Alternating Current) AC-DC Battery CE Complies with European Union Directives Double Insulated Electric Shock Fuse... - Page 5 The following definitions apply to the terms “Warning” and “Caution”. • “ Warning” identifies conditions and actions that may pose hazards to the user. • “ Caution” identifies conditions and actions that may damage the instrument being used. Use the calibrator only as specified in this manual, otherwise injury and damage to the calibrator may occur. Warning To avoid possible electric shock or personal injury: • D o not apply more than the rated voltage. See specifications for supported ranges.
- Page 6 • W hen servicing the calibrator, use only specified replacement parts. • T o avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator appears. • T o avoid a violent release of pressure in a pressurized system, shut off the valve and slowly bleed off the pressure before you attach the pressure module to the pressure line. Caution To avoid possible damage to calibrator or to equipment under test: • U se the proper jacks, function, and range for your measurement or sourcing application.
