Setting the Stabilization Criteria
When you move the leveling wafer, the readings typically need some time to stabilize. The bubble displays and
numerical readouts are shaded during this stabilization period. The length of time that the readings need to
stabilize depends on the type of leveling wafer, the operating conditions, and your required tolerance for stability.
For ALS2 and ALS2 Vertical wafers, MultiView determi
nes the necessary stabilization time automatically. You can’t
set the stabilization criteria for ALS2 or ALS2 Vertical wafers, so this section applies only to ALS1 systems.
The default stabilization time (20 seconds) and stabilization sensitivity (0.01 degrees) provide for the maximum
stability. These default settings yield the most accurate measurements for all types of situations. However, when
the position of the leveling wafer changes only a small amount between successive measurements, you can adjust
these settings so that you can work more quickly, without sacrificing accuracy.
To specify the stabilization criteria:
1)
Choose the menu item
Settings > Set Stabilization Criteria
. The Set Stabilization Criteria dialog is displayed, as
shown below.
2)
In the
Stabilization time
list, choose the number of seconds you want MultiView to pause to allow readings to
stabilize, or click
Use Default
to reset the time to the default 20 seconds.
3)
In the
Stabilization sensitivity
list, choose the fraction of a degree in pitch or roll movement that you want to
trigger MultiView to restart the stabilization counter. To reset the value to the default, click
Use Default
to
reset the sensitivity to 0.01 degree.
4)
Click
OK
.
