4.8.2 Explanation of Measurement Results in "Progress" Menu
After completion of the measurement, the following results appear in the "Progress" menu:
Figure 32: Head endurance run LS _1 result
Figure 33: Head endurance run LS _2 result
Legend:
1. Segment measured
2. Total number of cycles
3. Value determined Z down delta pick [µm]
This value is calculated by finding the difference between the lowest (Z min pick [µm] (11))
and the highest (Z max pick [µm] (12)) Z axis positioning value after switching the Z-down
light barrier during the pickup cycles.
This value must be within a plausible tolerance (in this case 0..150µm)!
Z down delta pick [µm] = Z max pick [µm] - Z min pick [µm]
4. Value determined Z down delta place [µm]
This value is calculated by finding the difference between the lowest (Z min place [µm]
(13)) and the highest (Z max place [µm] (14)) Z axis positioning value after switching the Z-
down light barrier during the pickup cycles.

This value must be within a plausible tolerance (in this case 0..150µm)!
Z down delta place [µm] = Z max place [µm] - Z min place [µm]
5. The Min DP time [ms] value is the shortest DP positioning time reached during positioning at
180°. This value must be within a plausible tolerance (in this case 100..250µm)!
6. The Max DP time [ms] value is the longest DP positioning time reached during positioning at
180°. This value must be within a plausible tolerance (in this case 100..250µm)!
7. Results display for number of successful strokes
8. Number of errors during 50x total cycles.
9. Results display (OK green tick / NOK red X)
10. Number of individual Z axis movements (in our case 50x down + 50x up = 100)
11. Z min pick [µm] is the lowest Z axis positioning value achieved after switching the Z-down
light barrier during the pickup cycles.This value is used to calculate the Z down delta pick
[µm] (3) value.
12. Z max pick [µm] is the highest Z axis positioning value achieved after switching the Z-down
light barrier during the pickup cycles.This value is used to calculate the Z down delta pick
[µm] (3) value.
13. Z min place [µm] is the lowest Z axis positioning value achieved after switching the Z-down
light barrier during the placement cycles.This value is used to calculate the Z down delta
place [µm] (4) value.
14. Z max place [µm] is the highest Z axis positioning value achieved after switching the Z-down
light barrier during the placement cycles.This value is used to calculate the Z down delta
place [µm] (4) value.

4.8.3 Explanation of Measurement Results Using Results PDF
These results can be seen if you scroll down the "Summary" menu or generate a results PDF!

Figure 35: Results PDF for head endurance run LS_2
Point 1:
The "Z down pick min/max" and "Z down place min/max" diagrams, plus the corresponding
measurements in the table, indicate that segment 6 deviates from all other segments both during
pickup and during placement! During both movements, this segment was not able to move as far
downwards as the other segments.
This might be due to difficulty moving the segment linear guide, to a defective cover switching ring
causing the light barrier to switch earlier or to the light barrier window in the CPP segment being dirty.
Point 2:
The "Z down pick min/max" and "Z down place min/max" diagrams, plus the corresponding
measurements in the table, indicate that segments 1 and 2 deviate significantly between pickup and
placement. The Z axis does not move as far downwards during pickup as it does during placement.
One possible cause could be that the DP linear guide have difficulty moving and that the segment or
DP linear guide may soon need replacing.
Point 3:
We can see here how the "Z down delta pick [ms]" value is calculated using the two threshold values
"Z min pick [ms]" and "Z max pick [max]". A value which is leaning towards the upper threshold (in this
example 150µm), indicates a problem with the linear guide for that segment.
