1-5. VCOM DC adjustment
Conditions
1. Test mode 50 % raster image
2. Provide 6.0 ± 0.05V voltage from DC in jack.
Adjustment and checking
(1) Execute 50 PERCENT GRAY on the test mode.
• While pushing down Flash and shutter button, turn the camera on.
• Push the Flash button twice then press MENU button (MENU 1 display will be shown.)
• Select 50 PERCENT GRAY then press the shutter button.
(2) Monitor the photo sensor amplifier output via a low-pass filter of cutoff frequency 60Hz.
Monitoring the oscilloscope screen, adjust VR320 to minimize 60Hz ripple waveform.
Notes:
Perform the adjustment after you replaced the display module.
Use only specified jig for replacing the flash lamp.
1-6. Current consumption check
Condition
Set the camera on play mode.
Adjustment and checking
(1) Current consumption (DC in = 6.0 ± 0.1V)
(2) Reducing the voltage from 6V, make sure that the battery capacity indicator is changed.
DC in = 4.65 ± 0.05V (Play mode)
Notes:
Maximum current in play mode; 500mA
Reference: maximum current in rec mode; 800mA (flash is not charging)
