  Shoot setting

 

(1)  Paste the chart.

 

•  Chart should be on the flat wall.

 

•  Illuminance level in the chart should be the same.

 

•  Make the tripod’s height and the center of the chart to the same height.

 

•  Enough space needed for shooting.

 

(2)  Set the camera.

 

•  Set [P] mode

 

•  Set [Maximum] size

 

•  Set ISO lowest level

 

•  Set Steady Shot [OFF]

 

•  Set Flash [OFF]

 

(3)  Set the camera on a tripod.

 

(4)  Adjust the position of the camera and the chart.

 

1. Set the zoom position of the camera at Wide end.

 

2. Attach the mirror onto the center of the chart.

 

    * The mirror should not tilt on the chart.

 

3. Set the camera to display the chart on LCD like in the following picture.

 

4. Adjust the camera position to the center of the chart.

 

    * Adjust the tripod height and the position (Lateral direction).

 

5. Adjust the camera angle to the frame of the chart with tripod.

 

    Remove the mirror.

  Shooting

      (1)  Set [Self-Timer]
      (2)  Shot
4

  Check the shot image.

      (1)  Check the shot image on PC.
 

100% Display (Display at the same magnification of its Pixel.)

 

Compare the image with the sample you set.

      No extreme focus blurring
      It should be distinguished the black and white by the sharpness between them.
      If it is in NG level, replace the lens unit.

<Reference>
•     How to Print the Chart
      Print “Forcus-Chart_A3.pdf” with printer.
      Print at the same magnification (It means 100 % size).
      Check the settings of printer to print in proper size.
•     Check of chart size.
      Make charts together and check if the size of charts is the following size.

NOTE:
•  -XX, -X mean standardized parts, so they may have some differences from the original 

one.

•  Items marked “*” are not stocked since they are seldom required for routine service. 

Some delay should be anticipated when ordering these items.

•  The mechanical parts with no reference number in the exploded views are not sup-

plied.

•  Due to standardization, replacements in the parts list may be different from the parts 

specified in the diagrams or the components used on the set.

• RESISTORS
  All resistors are in ohms.

The components identified by mark 0 

or dotted line with mark 0 are critical for 

safety.
Replace only with part number specified.
Les composants identifiés par une marque

Danger of explosion if battery is incorrectly
replaced.
Replace only with the same or equivalent
type.
Dispose of used batteries according to
the instructions.

•  Make sure that the flat cable and flexible board are not cracked 

of bent at the terminal.

  Do not insert the cable insufficiently nor crookedly.

•  When remove a connector, don’t pull at wire of connector. It is 

possible that a wire is snapped.

•  When installing a connector, don’t press down at wire of con-

nector. 

  It is possible that a wire is snapped.

•  Do not apply excessive load to the gilded flexible board.

The charging capacitor is charged up to the maximum 315 V 
potential.
There is a danger of electric shock by this high voltage when the 
capacitor is handled by hand.  The electric shock is caused by the 
charged voltage which is kept without discharging when the main 
power of the unit is simply turned off.  Therefore, the remaining 
voltage must be discharged as described below.

To preparing the short jig, a small clip is attached to each end of 
a resistor of 1 k

Ω /1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to 
prevent electrical shock.
