Print Page4. Apply the pressure with priming hand pump up and down, till the strength through the hand pump level is felt
hard, close the vent valve (oil drain valve).
5. Put the mass on the mass plate carrier, manually rotate the table clock wisely, the rotate speed is about (30~60)
r/min. Use the fine control screw press to adjust pressure, the measuring pressure value on DUT can be read
while piston position is between -10mm and + 10mm where is exactly between two lines on piston cylinder unit
on the floating indicator mirror. (When test piston area, the piston positon should be pointed to 0 mm and then
read the value )
6. After read the 1
pressure test point, use fine control screw press to decrease the pressure, plus the other
st
calculated mass sets and increase the pressure again, rotates the table to test next pressure test point. The test
of rest of pressure points is same as this method.
7. For down process measurement, decline the pressure with fine control screw press slowly. Reduces the
calculated mass set, and rotate the table again, read the pressure value on device under tester. Repeat the
operation till all test points are finished.
REMARK: DO NOT OPEN THE VENT VALVE DURING OPERATION, OTHERWISE THE PISTON POD WILL
BE BROKEN!
8. After measurement, open the vent valve, fully way into the screw rod of pressure wheel pump, close the vent
valve, disassembly the DUT, screws the quick connector plug.
