ADJUSTMENT

1. Complete Unit

1-1. Loading ADJ

Set QV-5000SX to “PLAY” mode.

(1) Connect QV-5000SX and DOS/V PC with link cable.

(2) Execute the adjustment software shown below on PC.

DT777E - aok 98042101.adj ENTER

(3) During the procedure, “MEMORY ERROR#4” appears on the display of QV-5000SX but this

does not indicate malfunction.

(4) Parameter loading complete message will be displayed.

1-2. White balance · Sensitivity adjustment

1. Preparation

(1) Viewer (Kenko light box handy 5000) (Modified in order to input DC externally)

(2) Voltage regulator (Output voltage: 0 to 10 V, Output current: 0 ~ 1 A)

(3) Use two ND filter together, one ND10 and one ND20.

(4) Use two color temperature converter filter together, one LA10 and one LA20.

*Although those filters are sold at a large camera store, they are available from CASIO. Please

refer to the parts list (page 31).

2. Setting of equipment

(1) Supply 6 V to simplified viewer from voltage regulator.

(2) Turn on power of simplified viewer and leave it on for more than 30 minutes.

3. Adjustment procedure

(1) Start test mode MENU2.

•Set function switch to REC mode

•Turn POWER switch ON while pressing DISP key and Shutter button simultaneously.

•Press mode key twice

•Press flash key and menu key simultaneously.

(On display, cursor is placed on CCD RGB ADJUST)

(2) Set the filter so that center of illuminance face and center of two color temperature converter

filters are lined up.

(3) Bring lens of QV-5000SX close to the center of color temperature converter filters then stick QV-

5000SX and filters together.

(4) Press the shutter button.

(5) When RGB ADJUST COMPLETE is displayed the initialization, of white balance is completed.

(6) Remove two color temperature filters from simplified viewer.

(7) Set the filter so that center of illuminance face and center of two ND filters are lined up.

Equipment needed to execute white balance and sensitivity adjustment

(8) Bring lens of QV-5000SX close to the center of ND filters, then stick QV-5000SX and filters

together.

(9) Press the shutter button.

(10) When SENS ADJ COMPLETE is displayed the adjustment of sensitivity is completed.

(11) Turn power switch off.

•When using kenko light box handy 5000 go on with the procedure listed below, 12. to 15.

Execute them only once. If you execute more than once start from procedure 1.

(12) Set function switch to PLAY mode, then turn on power.

(13) Connect QV-5000SX and PC with a link cable then execute R, BGAIN compensation software

(kadj1E.exe) on Windows 95.

(14) Click “replace AD”.

(15) White balance adjustment is completed when “AD replacement complete” is displayed.

4. Checking Adjustment

(1) White balance

•Set white balance manually to sunlight.

•Turn on the power switch of simplified viewer and take a picture.

•Compare it with a regular picture and if there are no difference, its setting is OK.

(2) Sensitivity

•Set strobe to AUTO.

•Take a picture of a person’s face in a dark room at a distance of about 1 meter.

•Compare it with a regular picture and if there are no difference, its setting is OK.

PRECAUTIONS

• Since the intensity of light and color temperature varies in the simplified viewer, let it sit for 30

minutes before using.

• The deviation of simplified viewer’s illuminace face’s point light intensity is large, try to set the

illuminace face at the center.

• Pay attention since the figure of R, BGAIN compensation software (kadj1E. exe) keeps changing.

1-3. Flash operation and recharge operation

• Apply 6.0 ±0.1 V voltage on DC in jack.

• Set QV-5000SX in “REC” mode.

• Perform after flash adjustment.

(1) Shoot a picture with flash ON.

(2) Shoot in red eye reduction mode.

(3) Shoot in macro mode.

(4) Set QV-5000SX in “PLAY” mode and check the pictures taken.

(5) Monitor the trigger waveform of (1), (2) and (3) on a digital oscilloscope and make sure there are

no errors.

(6) Shoot a picture with flash OFF. (Make sure there is no flash)

(7) Make sure that the charging current is less than 1.3 A.

Note: Make sure that the pictures taken in steps (1) and (2) are not whitish, dark or erroneously

colored.
