CE318-T Photometer
User Operation Manual
Revision V4.10 October 2021
26
After having done the corrections, repeat steps 20 and 21 to check again the position
of the sun spot. Repeat the correction until the sun spot is almost perfectly centered
on the target (few millimeters off maximum).
Note: The centering error will be compensated by the 4-quadrant sensor in the TRACK
process described in the next step.
22. Launch a TRACK SUN scenario in the CU menu. The robot will follow
the sun move. Check that the sun spot is centered on the collimator spot
at the end of the scenario. If a problem occurs, please read part 5.3.2.
Using a 4-quadrant sensor, the TRACK SUN scenario is guiding the robot to the point
where the intensity of the signal on both Silicon and InGaAs channel is the highest.
This intensity is corresponding to the center of the sun.
23. When the track is done correctly, repeat step 20, 21 and 22 once or twice
to validate the photometer behavior.
24. Tight the screws into the tray to fix the robot without changing its position.
Important note: watch out that the level didn’t move. If the level moved, go back to step
18 and after repeat step 20, 21, 22.
25. Format the SD card and the flash memory.
