3> Adjustment Program File

The programming for each item that is to be adjusted has to be done in the TXT format and saved on anSD card. The program data should be written as below, and can be saved in a TXT file and used.

< Adjustment Program >

A program for adjustment can be written in "Notepad", which is a basic Windows program. When saving, it can be saved as the file name "S483ADJ.TXT".

< Adjustment Procedures >

a...Prepare an AE Tester that supports LV of 12.

b...Save the corresponding adjustment file into the SD card.

c...Insert the SD card containing the program file into the camera and set the camera for the AE Tester.


Ⅲ. ADJUSTMENT

d...Mount the camera onto the AE meter and adjust the LV value to 12.

e...Turn the camera on.

f...A message for adjustment on the TFT LCD is displayed and automatic adjustment starts.

g...When the adjustment is complete, the camera will automatically be turned off.


Ⅳ. ADJUSTMENT

3) CCD GAIN ADJ

Measure the CCD gain of the camera.Since the actual CCD gain of one camera differs from another, this adjustment is for minimizing thedifference.






b...Place the camera onto the AE Tester.


Ⅲ. ADJUSTMENT

c...Set the LV value of the AE Meter to 12.

d...Save the corresponding adjustment file into the SD card.

e...Install the SD card containing the program file and turn the camera on.

f...The adjustment is conducted automatically.



Ⅳ. ADJUSTMENT

4) CCD DEFECT PIXEL

You can compensate for any defective CCD pixels in the camera.Adjust the defect pixel in the CCD after replacing the main PCB or the CCD. It is advisable to perform the adjustment of the defect pixel in the CCD after running a burning program.


a...Copy the corresponding adjustment file into the SD card.

b...Install the SD card containing the program file and turn the camera on.

c...The adjustment is conducted automatically.

d...When the adjustment is complete, the camera will automatically be turned off.


Ⅲ. ADJUSTMENT

5) BACK LASH ADJ

You can compensate for errors that occur when the lens barrel changes direction.Adjust the backlash after replacing the main PCB, the barrel and the CCD.


a...Copy the corresponding adjustment file into the SD card.


c...A message for adjustment on the TFT LCD is displayed and automatic adjustment starts.

d...When the adjustment is complete, the camera will automatically be turned off.


Ⅳ. ADJUSTMENT

6) B/T LEVEL ADJ

Set a warning voltage and lock voltage on the battery after replacing the main PCB.Required Equipment: POWER SUPPLY(2.71V)


a...Prepare the power supply.

b...Connect the power supply and the camera using the battery jig.


Ⅲ. ADJUSTMENT



c...Set the voltage to 2.71V.




Ⅳ. ADJUSTMENT

7) SHUTTER CLOSE TIME ADJ

You can adjust the close timing of the camera’s mechanical shutter.Compensate for a particular camera’s shutter timing deviation because each individual camera is different.To adjust SHUTTER CLOSE TIME after replacing the MAIN PCB, BARREL or CCD.






b...Place the camera onto the AE Tester.


Ⅲ. ADJUSTMENT

c...Set the LV to 12.






Ⅳ. ADJUSTMENT

8) LRIS ADJ

Adjust the differences between the stages of the camera shutter.When using a multi-stage shutter, there is a difference in the aperture value of each stage of the shutter.Therefore reduce the difference by adjusting per set.






b...Save the corresponding adjustment file into the SD card.

c...Insert the SD card containing the program file into the camera and set the camera for the AE Tester.


Ⅲ. ADJUSTMENT

d...Place the camera onto the AE Meter and set the LV to 12.

e...Turn the camera on.

f...A message for adjustment on the TFT LCD is displayed and automatic adjustment starts.

e...When the adjustment is complete, the camera will automatically be turned off.


Ⅳ. ADJUSTMENT

9) FLASH ADJ

Limit range of brightness of the flash in order to identify hardware defects.Fires the flash at each EVC level - -1EV, 0EV, and 1EV - in order to identify cameras that are out of thepermitted specification range, and acquires the R and B gain of the flash.


a...Put up a piece of 36% Reflector Paper in the darkroom.

b...Set the camera up in a darkroom, using a tripod.

c...Set the distance between the Reflector Paper and the camera at 80cm.

[ Specifications for the subject's distance ]Point the camera towards a building or a subject from an infinitive distance (the chart is not used).Adjust the punt using a subject as a point of reference from an infinitive distance such as a building or an object outdoors.- Subjects without contrast, such as the sky in mono-color and a snow-covered landscape.- Aim at a place further than the infinitive distance specified in the product specifications.

C...Save the corresponding adjustment file into the SD card.

✽A subject which is further away than the infinitivedistance specified by the product.

[ External Subject ]


Ⅲ. ADJUSTMENT

d...Install the SD card containing the program file and turn the camera on.

e...The adjustment is conducted automatically.

① The OSD on the LCD monitor is cleared after booting (preview mode only).

②Operate with the specified shutter (big/small).

③ Adjust the punt as per the position of the zoom.

④ Carry out inspection by referring to the specifications as per the zoom step.

⑤ Carry out a fast inspection by setting a short scan range.

⑥ Carry out the inspection with the long scan if it is out of the short scan range.

⑦ Carry out inspection by referring to the gradient variations for each zoom stage.

⑧Write the adjustment value in the EEPROM by referring to the EEPROM WRITE data.

⑨Write the result of the adjustment value in the data file by referring to the CARD WRITE data.

<Adjustment Method>

Open and check a CSV file created in the memory card for adjustment.


Ⅳ. ADJUSTMENT

11) BURNING TEST

This is to detect hardware or software defects in a camera by repeated use of the camera functions.If the following program for adjustment is used, burning will be done first and then the automatic adjustmentof the defect pixel in the CCD will be performed.


a...Save the Burning program into the SD card.


c...The camera functions will automatically run in the predetermined order.

※ If the test is completed successfully, the "Burning..END" message will be displayed on the LCD and thenthe camera will automatically be turned off.


Ⅲ. ADJUSTMENT

12) EEPROM READ

This reads the data saved in the EEPROM of the camera and writes the data as a data file.

< Procedures >

a...Save the EEPROM READ program into the SD card.


c...If you turn the power on, the camera automatically reads the data saved in the EEPROM and saves thedata into the SD card as a file.

d...When all data are read and saved into the SD card, turn the power off.

e....If you insert the SD card into a PC, you will be able to find the XXXX.CSV file.


Ⅳ. ADJUSTMENT

13) EEPROM WRITE

You can write data onto the EEPROM according to the procedures below.

< Procedures >

a...Save the EEPROM data into the SD card.

b...Install the SD card and turn the camera on.

c....If you turn the power on, the camera automatically writes the data onto the EEPROM.
