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.

Symbols Used in this Manual

In this manual, a Warning identifies conditions and actions that pose a hazard to the user.
A Caution identifies conditions and actions that may damage the Pneumatic Deadweight
Tester.
Symbols used on the Pneumatic Deadweight Tester and in this manual are explained in
Table 1-1.

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.
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.
