Operation • PREPARING TO GENERATE PRESSURE Close the vent valve. It may be necessary to prime the pump, particularly for first time use, or if the pump has been inactive for an extended period of time. Note: Refer to Priming on page 10 for instructions on priming the pump. -
Page 14: Adding Weight Masses
Operation • ADDING WEIGHT MASSES Weight masses are suspended from the weight carrier tube, which is suspended from the piston assembly. Weight placed on the weight carrier tube should be equal to between 90% and 100% of the range of the device under test. A piston assembly, in combination with a weight carrier tube, will produce its own pressure (based on its force and mass). - Page 16 Operation • Repeat steps 7 through 9, adding weight to equal the pressures of the remaining test points for the device under test, and recording each reading. If hysteresis performance is desired, proceed to step 11. If hysteresis performance is not desired, proceed to step 16. Remove weight from the weight carrier tube to equal the pressure of the first descending test point for the device under test.

Carefully insert the cylinder, with the membrane attached, into the column body. Note: MGAAA instrument oil and a plastic fill bottle are necessary to complete this procedure. Both the oil and bottle may be ordered from AMETEK. Type T Hydraulic Deadweight Tester Operation Manual... - Page 21 Maintenance and Replacement • Push the capillary tube of the instrument oil bottle through the center of the cylinder, into the isolating membrane. Squeeze the oil bottle to fill the membrane up to the bottom of the cylinder bore. Using the hand pump, carefully pump fluid into the column to compress the membrane and bring its fluid level to the top of the cylinder. Coat the piston with a light film of MGMA oil.

Page 22: Cleaning
Maintenance and Replacement „ CLEANING Each M&G piston and cylinder assembly is tested within very close tolerances during manufacture for pressure retention (leak rate), for sensitivity, and for ac- curacy of calibration. Each assembly is then cleaned, identified by a serial number and stored until shipped. CAUTION: A piston and cylinder assembly is a very closely fitted assembly. -

Support • TROUBLESHOOTING Failure to Pump ► Problem: The pump fails to develop pressure when the hand lever is operated. ► Verify that the vent valve is closed and that there is sufficient fluid in the reservoir. If necessary, add fluid through the fill plug and follow the Pump Solution: Priming Procedure. - Page 27 Support • ► To Replace the Vent Valve 0-ring Apply a wrench to the nut at the base of the pressure relief valve. Remove the vent valve and its o-ring. Remove the relief valve seat and its o-ring. Relief Valve Seat 0-ring �...

„ RECOMMENDED RECERTIFICATION PROCEDURES All deadweight pressure testers produced by AMETEK, M&G are tested and certified in the M&G laboratory for accuracy of pressure produced, with results traceable to the National Institute of Standards and Technology. In addition, if ±0.025% or ±0.015% accuracy is required, data is furnished showing nominal and observed pressures within the upper 90% of the range of each piston and cylinder, with results directly traceable to the National Institute of Standards and Technology. - Page 39 Support • Test Equipment Depot - 800.517.8431 - 99 Washington Street Melrose, MA 02176 - TestEquipmentDepot.com ► Figure 3.3.
