20-1. Steady Shot Adjustment (1)
Subject Pattern A
(1.5m from the front of the lens)
Measurement Point Video output terminal
Measuring Instrument Oscilloscope
(V period)
Adjustment Page F
Adjustment Address 41
Fig.5-1-13.
Adjusting method:
1) Select page: 0, address: 01, and set data: 01.
2) Select page: F, address: EA, set data: 76, and press the PAUSE
button of the adjustment remote commander.
3) Expose pattern A with the zoom TELE end.
4) Adjust the focus.
5) Measure the vertical position SV1 (msec) of the falling edge
of the waveform. (Oscilloscope is V period)
6) Select page: F, address: EA, set data: 8A, and press the PAUSE
button.
7) Measure the vertical position SV2 (msec) of the falling edge
of the waveform. (Oscilloscope is V period)
8) Obtain D41' using the following equation (decimal calculation).
NTSC model
D41' =
1.53
×
0.6
× 99
SV1 – SV2 PITCH sensor sensitivity
PAL model
D41' =
1.84
×
0.6
× 99
SV1 – SV2 PITCH sensor sensitivity
Note: PITCH sensor sensitivity (SE601 or SE602 of SE-108 board)
is written only on the repair parts.
9) Convert D41' to hexadecimal notation, and obtain D41. (Round
off to one decimal place)
(Refer to Table 5-4-1. “Hexadecimal notation-Decimal notation
conversion table” of “5-4. Service Mode”. )
10) Select page: F, address: 41, set data: D41, and press the PAUSE
button.
Processing after Completing Adjustments
1) Select page: F, address: EA, set data: 80, and press the PAUSE
button of the adjustment remote commander.
2) Select page: 0, address: 01, and set data: 00.
3) Check that the steady shot operation is performed normally.
