1.  Turn on the air-leak tester.
2.  Hold the vacuum pad on flat surface, set the air switch to “open”, and adjust the pressure to around -5.0 by turning the pressure adjust-

ment knob.

 

Inspection pressure:-45.0 ±3.0 kPa

 

3.  Confirm that there is no dust on the vacuum pad and test hole, and hold the vacuum pad by pressing it vertically to the center of test hole 

on the camera.

Keep vacuum pad vertically by touching with finger.

Do not keep pressing it to the camera.

value may be changed.
Perform the measurement under no vibration.

It may cause the air-leak under the condition with vibration.

4.  Wait 150 seconds with keeping the pressure at near -5.0 kPa (-8.0 kPa to -2.0 kPa).
5.  Wait 10 seconds with setting air switch to “close”, and write the indicated value.
6.  In addition, leave for 1 minute, and check the pressure changes value is satisfied the following value by comparing between the written 

indicated value and indicated value.

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 150 seconds with keeping the pressure at around the -5.0

k

Pa (within -2.0kPa to -8.0kPa).

Caution:  Do not operate the hand pump after settling the change value.

If operate the hand pump again, wait 150 seconds form then.

The changed portions from
Ver. 1.0 are shown in blue.
