4-68 System Configuration and Setup
Teach 1 Center Point is used to teach the location of an object that has an easily
identifiable center, like the Tactile Sensor or the Purge Station.
Teach 3 Circumference Points is used to teach the location of an object that does not
have an easily identifiable center, like the Scale Station.
!Measurement cycles refers to the number of tests performed. Generally, three tests
are sufficient.
!Offset tolerance is a plus or minus value that each measurement must be within, relative to
each other, in order for the test to succeed. The default value is 0.002.
!Needle-to-Probe Z Offset is the measurement taken.

27. Use the Position Controls to center the Camera crosshairs on the center of the Tactile Sensor.
28. Click on
Teach.
!The Dispensing Head automatically performs a height sense on the Tactile Sensor. The
number of height senses performed is the number of Measurement cycles.
!The Needle-to-Probe Z offset is recorded and shown. If any of the measurements fall
outside of the offset tolerance, relative to each other, the results will indicate as such and
you have the choice of retrying the test or canceling.
29. Click on
Done.
!A new Teach Window opens asking you to select a method for teaching the Purge
Station location.
Teach 1 Center Point is used to teach the location of an object that has an easily
identifiable center, like the Tactile Sensor or the Purge Station.
Teach 3 Circumference Points is used to teach the location of an object that does not
have an easily identifiable center, like the Scale Station.
Center location is the current XYZ coordinates for the Purge Station.
!Needle-to-Height Sense Z Offset is a positive or negative number, which determines how
deep the needle descends into the purge boot. The number is relative to the height sense
taken after teaching the center location. The height sense is taken on the Purge Station lid,
so a positive offset number means that the needle will descend that much deeper into the
purge boot. A negative number means that the needle will stop that much above the Purge
Station lid.
