4) Use the “yellow frame” to enclose a row of white holes in the left hand side window.

Don’t make the yellow frame too big.

Note: There should be only round patterns with black background inside yellow

frame or it may cause failed counts in [Pattern No.].

5) Click “Calculate” to calculate the resolution.

6) Check the resolution value in the [Resolution] dialogue.

7) If the resolution value is below 20 µm, input a number in the Move (Z) dialogue and

click [Up Arrow Button] (No.8 in the below figure). Then repeat the step (2)-(6) until the

resolution is within 0.01 of 20 µm.

8) If the resolution value in the [Resolution] dialogue is over 20 µm, input a number in the

Move (Z) dialogue (No.7 in the below figure) and click [Down Arrow Button]. Then

repeat the step (2)-(6) until the resolution is within 0.01 of 20 µm.

9) Click [Save] and continue to calibrate other resolutions.

10) After calibrating the 7 µm, 10 µm, 15 µm, and 20 µm resolutions, click [Close] to

complete the Resolution Calibration.

Note: In order to prevent the actual resolution is different from the selected

resolution, try to alternatively switch between different resolutions in step (1)

before start step (2). For example to calibrate 20 µm, first choose 20 µm --> then

choose 15 µm--> wait until the camera and tube move to the correct height -->

choose back to 20 µm again--> wait until the camera and tube move to the correct

height-->start to calibrate.

2.2 Camera Shift Calibration

 Go to [Utility]  [System Calibration]  [Camera Shift]

Figure 16: Utility/System Calibration/ Camera Shift

 Calibrate low, median and high resolution (20, 15, 10µm) one by one by following the

procedure below which takes high resolution as an example.

1) Click [High Resolution] in Camera Shift Calibration dialogue and Camera Shift

Modification Dialogue.

2) Press [Reset].

3) After press [Update Shift] and [Save to Reg.] in sequence, every value in Camera Shift

Modification Dialogue will become zero.
