3. Press the hand pump slightly so that the indicated pressure value becomes to “-5.0”.
Few seconds later, decrease the pressure slightly. Therefore adjust the indicated pressure by pressing the hand pump.
Note: Perform the pressure adjustment by hand pump pushing amount.
If the pressure becomes too high, perform the adjustment again after removing the vacuum pad.

4 The change value is getting settle, wait 120 seconds with keeping the pressure at around the -5.0kPa (within -0.0kPa to -10.0kPa).
Caution: Do not operate the hand pump after settling the change value.
If operate the hand pump again, wait 120 seconds form then.
5. Write the indicated value, leave for 1 minute, and check the pressure changes value is satisfied the following value by comparing between written
indicated value and indicated value.
