Setting Compensation (Only in Real 10 Mode)
To adjust the printing magnification used in printing in the Real 10 mode, follow the procedures below.
1 Open the [SETUP MENU: ADDITIONAL] screen and
press the [PRINT TEST] button in the [PRINTER
(PictBridge)] area to print an object image.
An image with the overlaid scale in pixels is printed.
2 Physically measure the dimension of the scale on the
print.
Example: Measure distance between 0 and 500 pixels.
3 Use the following conversion formula to calculate
dimension of the scale on the object from reading of the
scale (in pixels).
Nikon DS-L3 Test Print
0 500 1000
Conversion formula:
• Dimension of scale on object
Reading of scale (in pixels) X Pixel size of image pickup device
Optical magnification (objective lens magnification X relay lens magnification)
Example of calculation: Reading of scale = 500 pixels

Dimension of Scale on Object
DS-Fi2
DS-Fi1
DS-Fi1c
3.4 μm
Objective lens: 40x
Relay lens: 0.7x
500 pixels x 3.4 μm / (40x X 0.7x)
= Approx. 61 μm
DS-Vi1 4.4 μm
Objective lens: 40x
Relay lens: 0.55x
500 pixels x 4.4 μm / (40x X 0.55x)
= Approx. 100 μm
DS-Qi1Mc
DS-Ri1
6.45 μm
Objective lens: 40x
Relay lens: 0.7x
500 pixels x 6.45 μm / (40x X 0.7x)
= Approx. 120 μm
4 Press the [CMP(50-150%)] button and enter scaling
ration compensation value.
When this button is pressed, a keypad appears. Enter a
desired number and press the [ENTER] key.
Adjust magnification so that the following equation is true.
Dimension of the scale on the print / Dimension of the
scale on the object = Magnification factor of optical
equipment
5 Repeat steps 1 to 4 and obtain a more precise value.
