Chapter 3 Operation Connections Connect the EUT to the test station using a gauge adapter and lens ring from the selection provided. W Caution This unit can generate very high pressures and, as a consequence, only metal-to-metal sealing is acceptable, i.e. no sealing washers of any description should be used (see Figure 3.1 and 3.2 for methods of sealing). -

Page 12: Turn Capstan Fully Clockwise
Operation Procedure for Removing Trapped Air from System 1. Open HP valve (1) and LP valve (2) fully, (counter-clockwise). 2. Open reservoir valve (3), (approximately 4 turns counter-clockwise). 3. Turn capstan fully out (counter-clockwise), and wait for approximately 60 seconds. glf05.bmp Figure 3-4. -

P3800 Series Users Manual Procedure for Priming the Pressure Intensifier glf06.bmp Figure 3-5. Prime the Pressure Intensifier 1. Close LP valve (2) by turning fully clockwise. 2. Turn capstan in (clockwise) until resistance is felt. This is a result of the pressure required to move the intensifier piston backward in its cylinder, and to lift the measuring piston and weight carrier. -

P3800 Series Users Manual glf08.bmp Figure 3-7. Close Reserve Valve 4. Close reservoir valve (3). 5. Turn capstan in to generate system pressure. The displaced fluid from the ram screw moves the intensifier piston, generating system pressure to lift the measuring piston and weights. -
Page 16: Correct Float Position
Operation Generating Calibration Pressure W Caution When reducing pressure ALWAYS use the capstan (by winding out counter-clockwise). NEVER use any of the valves. When reducing from high system pressures, some pressure is still retained in the system, even after winding the capstan fully out (approximately 700 psi / 50 bar). -
Page 17: Maintenance
Chapter 4 Maintenance Introduction The P3800 Series of High Pressure Deadweight Testers have been designed to require minimal maintenance. Routine maintenance entails keeping the unit clean and free from excess oil. The operating fluid should be changed at regular intervals due to potential contamination from items under test. -

Page 20: Recalibration
Chapter 5 Recalibration Introduction To maintain the highest accuracy the DWT should be recalibrated at regular intervals. The exact period between recalibrations is dependant on ambient conditions and use. As a general guide, recalibration period should be more than 1 year and less than 3 years.

Page 21: Pressure Corrections
Chapter 6 Pressure Corrections Introduction Pressure correction is required for high accuracy work and is due to the effects of pressure on the PCU assembly during operation. By reference to the certificate of calibration provided the actual pressure in the system can be obtained. All values relate to the environmental conditions stated on the certificate. - Page 22 P3800 Series Users Manual Temperature and Gravity Corrections Deadweight testers are manufactured to give an accurate pressure reference at the specified temperature and gravity values indicated on the certificates. The following Standard Values are applied during calibration unless otherwise requested during manufacture (see Certificate).
