12. Steady shot adjustment
• Perform the steady shot adjustment only when replacing the
angular velocity sensor. When the microprocessor, circuit, etc.
malfunctions, do not perform this adjustment but check operations
only.
• Record the sensitivity label of the angular velocity sensor (repair
part), including to which side of the board it was attached to, etc.
If it has been attached incorrectly, the image will move up and
down or to the left and right during steady shot operation. Be sure
to take note of this.
Precautions on the Parts Replacement
There are two types of repair parts.
Type A ENC03EA or ENC03JA
Type B ENC03EB or ENC03JB
Replace the broken sensor with a same type sensor. If replace with
other type parts, the image will vibrate up and down or left and
right during hand-shake correction operations. After replacing, re-
adjust according to the adjusting method after replacement.
Precautions on Angular Velocity Sensor
The sensor incorporates a precision oscillator. Handle it with care
as if it dropped, the balance of the oscillator will be disrupted and
operations will not be performed properly.
Switch setting:
1) Steady Shot (Menu display) ...........................................ON
2) Digital zoom (Menu display) .........................................OFF
Adjusting method:
1) Expose pattern A with the zoom TELE end.
Note:
Digital zoom (Menu display) ............................... OFF
2) Adjust the inclination of the camera so that the vertical black
line comes to the center of the screen.
3) Select page: 0, address: 01, and set data: 01.
4) Select page: E, address: 4E, set data: 08, and press the pause
button of the adjusting remote commander.
5) Adjust to the falling edge of the waveform with vertical scale
on the oscilloscope. (Oscilloscope is H period).
6) Select page: E, address: 4E, set data: 09, and press the pause
button of the adjusting remote commander.
At this time, measure the moving amount t1 (
µ
sec) of the falling
edge of the waveform.
7) Obtain D
44
' using the following equation (decimal calculation).
D
44
' = (4.00/t1) x [0.58/(SE602 sensor sensitivity)] x 84
Note: The SE602 sensor sensitivity of the VP-47 board is labeled
only on the repair part.
8) Raise D
44
' to a whole number, convert it to a hexadecimal digit
and take this as D
44
. (Refer to Table 5-1-2. “Hexadecimal
notation-Decimal notation conversion table”.)
9) Select page: F, address: 44, set data: D
44
, and press the pause
button of the adjusting remote commander.
10) Select page: E, address: 4E, set data: 08, and press the pause
button.
Procedure after adjustment
1) Select page: 0, address: 01, and set data: 00.
2) Check that the steady shot operation is performed normally.
