3.10 Zero Shift
In this calibration, put the calibration board into the machine manually and
clamp it. In this way, when the front door is opened and amplifiers are set
up, the calibration board can be held and the zero height of its top surface
can be fixed.
This step is used to set up the zero height for 3 amplifiers.
1) Click on [Laser Offset].
2) In order to set up Laser Sensor0, choose [0] in the [Sensor Index] field.

3) Click [Set Scan Info(XRay)]. Set up the scan parameters and click on [OK].

4) Click on [Scan (XRay)]. Do not use the [Scan] buttons shown as below to scan
the board.

5) Click on [(P1(XRay))]. Move the box to one column circles closely, but still keep
the box on the metal surface, so amplifiers can record the metal surface as zero
height. Click on [ok] to save the box coordinates. You only have to assign the box
position once, and Laser Sensor0, Laser Sensor1, and Laser Sensor2 can move
to this box position later.

6) Click on [Move To] and then sensor0 will move to the assigned place. Go to the
machine and check if the spot of Laser Sensor0 is moved to one column circles
closely.

7) There are 3 amplifiers on the top of X-ray tube. Find the amplifier0 that detects
the spot of Laser Sensor0. If unable to determine which amplifier detects Laser
Sensor0, use finger to block the spot of Laser Sensor0. Meanwhile, the amplifier
that changes its value dramatically is the amplifier0.

8) On the amplifier0, press the [Zero Shift] button twice to set up zero height for
amplifier0.

9) Choose [1] in the [Sensor Index] field.
10) Click on [Move To]. The Laser Sensor1 will move to the assigned position that
has been saved in [P1(XRay)] step.
11) Use the same way mentioned above to find out the amplifier1. Press the [Zero
Shift] button twice on the amplifier1 to set up the zero height.
12) Choose [2] in the [Sensor Index] field.
13) Click on [Move To]. The Laser Sensor2 will move to the assigned position that
has been saved in [P1(XRay)] step.
14) Find out the amplifier2. Press the [Zero Shift] button twice on the amplifier2 to set
up the zero height.
