1-4.  AIR-LEAK TEST
1-4-1. Inspection Procedure (Compressor Type)
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 adjustment
 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.

Caution :
Keep vacuum pad vertically by touching with finger. 
Do not keep pressing it to the camera.
Do not touch the tube during the measurement, or measurement
value may be changed.
Caution:
When performing air leak test, peel off the Microphone Sheet
(4-427-606-01) and stick Cover Tape (Microphone) (4-427-546-01).
After the test has been completed, peel off the Cover Tape

4.   Wait 120 seconds with keeping the pressure at near -5.0 kPa.
5.   Wait 30 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.

Caution: Do not open the connector cover and the battery/memory card cover for two minutes after the leak test.
Note: If the measurement result does not meet the specification value, check the compressor setting value and retry inspection.
