Crosshair probe data collection parameters
Data collection parameters for crosshair probes include:

• Crosshair timeout delay

• Motion distance

• Line thickness

Crosshair timeout delay

When the auto-enter function is enabled during feature measure-

ment on the LCD Video screen, a point is collected by the sys-

tem each time the stage is moved to position the part under the

crosshair. This automatic point entry is delayed until the stage

has been motionless for a short time to ensure that the crosshair

is located where the user intended. This delay is the Crosshair

Timeout. This parameter is identical for the straight and offset

crosshair probes. The default value will provide adequate delay

for most applications, but can be increased to accommodate more relaxed probing.

To specify Crosshair Timeout, touch the Crosshair Timeout data field and enter the desired delay in sec-

onds using the number keys.

Motion distance

As described above, when the auto-enter function is enabled, a point is collected by the system each time

the stage is moved to position the part under the crosshair at a new location. This automatic point entry is

delayed until the stage has been motionless for a short time to ensure that the crosshair is located where the

user intended. This delay is restarted if the stage moves again during the timeout interval to facilitate final

fine adjustments of stage position.

To specify the minimum stage movement required to restart the crosshair timeout delay, touch the Mo-

tion Distance data field and enter the desired stage

motion in the current unit of measure (millimeters

or inches).

Line thickness

The lines of the crosshair probes can be changed in one-pixel increments from 1 to 3 pixels. To specify

the line width of the crosshair probe, touch

the Crosshair Thickness data field and enter

1, 2 or 3 pixels.

The auto-enter function is enabled on

the LCD video screen
