P3000 Series Users Manual Compressed Gas Use of compressed gas can create an environment of propelled foreign matter. Pressure system safety precautions apply to all ranges of pressure. Care must be taken during testing to ensure that all connections are properly and tightly made prior to applying pressure. Personnel must wear eye protection to prevent injury. Heavy Weights Lifting and movement of heavy weights can create an environment of strain and impact hazards. Care must be taken during testing to ensure that weight masses are lifted in a manner that avoids over-reaching or twisting, and that the masses are not dropped. Personnel must wear reinforced safety shoes to prevent injury. Personal Protective Equipment Wear eye protection and reinforced safety shoes approved for the materials and tools being used.

Go to Fluke's website for recycling information. Operating Principle Deadweight Testers are the primary standard for pressure measurement. Utilizing the well-proven Piston-Gauge system, consisting of a vertically mounted, precision lapped Piston and Cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. PRESSURE = FORCE AREA Each weight is marked with the tester serial number, and the pressure measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly. 1-2 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664
