Measurement
Measure this changed value.
One minute later, it is OK
if the value within 0.45 kPa.
1-4-2. Inspection Procedure (Hand Pump Type)
1. Turn on the air-leak tester.
2. Keep the vacuum pad by pressing it to the center of test hole on the camera.
OK
Tilt
NG
Test hole
Air leak
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.
Perform the measurement under no vibration.
It may cause the air-leak under the condition with vibration.
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.
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.
OK
Tilt
NG
Test hole
Air leak
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.
Perform the measurement under no vibration.
It may cause the air-leak under the condition with vibration.
4. Wait 120 seconds with keeping the pressure at near -5.0 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.
Specification value
0.45 kPa or less: OK
0.46 kPa or more: NG
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.
