10-8 Height Sensor
Probe Height Adjustments
An operator can make small-scale adjustments to probe height using the micrometer
adjustment. Only a service technician should make large-scale adjustments to probe height.
Service technicians can also adjust the Z-Axis velocity and acceleration. The Z-Axis velocity
and acceleration values are applied to the dispense head during a height sense and can
increase throughput. See the specifications on page 10-14 for more information.
Tools and Materials Needed
• 1/16-inch hex key (for large-scale adjustments)
To make small-scale adjustments to the probe tip height:
1. Install the needle you will be using.
2. Loosen the micrometer locking screw (see Figure 10-1).
3. Turn the micrometer to raise or lower the probe.
> In Selective Mode, the recommended probe height is 2.54 mm (0.10 in) below the
needle tip (see Figure 10-4).
TIP Use the ruler etched into the side of the micrometer to determine
probe height.
4. When you are satisfied with the probe height, tighten the micrometer locking screw.
? NOTE After installing or adjusting the Height Sensor, you must run a Valve
Offsets or Calculate Master Offsets routine. This should be done every time
you change the needle.
