14. [Adjustment] SR adjustment- 1
[Caution 1] When replacing T100 or C000 block, you must excute this adjustment.
[Caution 2] Excute the adjustment on the stable table and do not give vibration to the camera while adjusting
[Required equipment]
Programmed software for 76700 (for SR unit adjustment), SR adjustment stand
Computer (Windows 2000 or Xp, USB port as standard equipment), USB cable, AC adaptor,
Lens (FA 50mm), SD card for confirmation (For test mode OFF)
14-1. Setting for computer
Copy the folder [76700 SR Operation Adjustment] to the PC
14-2. Preparation
SR adjustment stand
(1)Set the AF mode lever to [MF].
(2) Attach SR adjustment stand to the camera
(3) Put the camera on the stable table with lens downward.
14-3. Content of Adjustment
SR0 : [Coil direction check] Driving direction check
The direction of the drive when the coil's passing an electric current is checked.
SR1 : [
す
sensor sensitivity adjustment]: Positional detection gain adjustment
To secure the resolution of the amount of the shaking correction, the positional
detection resolution of the hole sensor is adjusted in the maximum.
SR2
：
[Movement range adjustment]
：
Correction range limit adjustment
す The current greatly flows to the coil when the correction mechanism controls and attaching to the
mechnical limit and it influences to the camera. Therefore, the limit within the electric range of the
correction is decided
SR3
：
[Gyro offset adjustment]
：
Gyro off sett adjustment
The offset voltage of the giro signal processing circuit is added to the giro output signal and the correction
performance is ruined. Then, the offset voltage of the giro signal processing circuit output is adjusted to a
standard voltage.
