Page 8: Operating & Storage Specification
General Information Environmental Corrections When the gas pressure within the system balances the combined downward force of the piston and weights, the piston and weights will float freely and the system is in equilibrium. The design of a Piston/Cylinder Unit (PCU) fitted to a deadweight tester allows for a very small clearance gap between the piston and cylinder. -

Page 13: Preparation
Chapter 2 Preparation Introduction The deadweight tester must be set up on a level, stable workbench or similar surface. If instrument has fitted handpump, remove pump handle form tool roll and fit to pump arm. Level the tester using the four adjustable feet to the bubble level attached to the top plate. Connection to External Pressure/Vacuum Supplies Connection ports in the rear panel of the instrument are 1/4 NPT. -

Page 17: Test Port Insert
Preparation Connections Test Port Insert For devices with 1/8 BSP or NPT mounting threads, the diameter of the thread is very close to the effective sealing diameter of the O-ring fitted to the test port. This can make it difficult to achieve a good seal. When mounting these devices, use the test port insert (stored in the spare seals container) as shown in Figure 2-6. -
Page 18: Operation
Chapter 3 Operation Introduction All P3000 Series pneumatic deadweight testers have a monitor gauge fitted to the instrument top plate, to serve as a guide to the operator by indicating the approximate pressure in the system. Single PCU Models — Pressure 1. -
Page 19: Single Pcu Models - Vacuum
P3000 Series Users Manual 8. Depressurize the system by SLOWLY opening the Exhaust valve, as sudden depressurization will cause the weight stack to fall quickly, which may damage the piston assembly. 9. Remove the weights from the piston. Single PCU Models — Vacuum 1. - Page 20 Operation Dual PCU (Pressure & Vacuum) Models 3. If either the system or handpump selector valve is set for vacuum, when pressure is applied to the system, the safety valve fitted to the front of the PCU mounting assembly will be ejected, venting the system. (The safety valve is retained by the assembly, and will not “fly-out”...

Page 21: Calibration In Different Pressure Units
Chapter 4 Calibration in Different Pressure Units Introduction The deadweight tester can be used to calibrate in different pressure units in either of two methods. Conversion Weights A set of Conversion Weights can be supplied, marked in the required pressure unit, and adjusted to the correct mass for use with the existing piston(s). -
Page 22: Maintenance & Servicing
Chapter 5 Maintenance & Servicing Introduction Note The piston/cylinder assembly is the most critical and sensitive part of the deadweight tester. To maintain accuracy, the piston must always slide freely in the cylinder, and the gas supply must remain clean and dry. The Figures on the following pages detail the components of each assembly, together with the relevant part numbers. -
Page 23: Piston Re-Assembly
P3000 Series Users Manual W Caution Never touch the working surface of a clean piston with bare fingers — the natural oil in your skin can cause the piston and cylinder to stick. 8. Wipe any dirt or moisture from the outside surfaces of the cylinder (2). -

Page 36: Fault Finding
Chapter 6 Fault Finding Poor PCU Spin/Sensitivity The clean pneumatic piston/weight carrier assembly will rotate freely, without additional weights, slowing down gradually to a complete stop. If the rotation stops quickly, then the PCU may be dirty and require cleaning. If the piston “squeaks” when rotated, it must be cleaned immediately, see Chapter 5, Maintenance &... -
Page 37: High Pcu Fall-Rate
P3000 Series Users Manual High PCU Fall-Rate The piston will always fall slowly as the gas passes between the piston and cylinder. However, this fall rate will never be so fast that a stable reading cannot be made. 1. The system may be leaking. Check that exhaust valve is fully closed, and test port connections are correctly made. -
Page 38: Storage & Transportation
Chapter 7 Storage & Transportation Instrument 1. Shut-off any external supplies, and depressurize system by slowly opening both Inlet and Exhaust valves. 2. Disconnect external supplies. 3. Remove screw-in handle from handpump arm (if fitted) and store in tool roll. 4. -
Page 39: Ancillary Equipment
Chapter 8 Ancillary Equipment Dirt/Moisture Trap, P5531 If there is any doubt that the instrument to be tested is not internally clean, then the addition of the P5531 Dirt/Moisture Trap will protect the deadweight tester from contamination and possible damage. Any particles or moisture present within the DUT will fall into the clear, acrylic chamber, where they can be seen by the operator. -
Page 40: Angle Adapter, P5543
P3000 Series Users Manual Angle Adapter, P5543 To calibrate gauges with the pressure connection on the rear (e.g. panel-mount gauges) in their correct position, an angle adapter should be used. The angle adapter fits directly onto the test station, converting it through 90 degrees, allowing the standard adapters to be used.
