Raising and Lowering the Sensor
The sensor mounting pad (Z axis slide) on your Cobra includes the following
two components:
•
The knurled Focus Knob is located on the right side of the sensor mounting
pad, as shown in Figure 3-1, and is used to raise or lower the sensor to focus
the sensor on the surface of a part. Twist the Focus knob clockwise to raise
the sensor and counter-clockwise to lower it (make sure the Locking knob is
not tightened).
•
The Locking Knob is located on the left side of the sensor mounting pad,
as shown in Figure 3-1, and is used to lock the Z axis slide in position when
the sensor is at the optimal position. We recommend that you tighten the
Locking knob before performing a scan.
Note:
When you tighten the Locking knob, the sensor cannot be raised or
lowered.
On-line Help: See the topic, How to Focus the Sensor , for more information on
focusing the sensor.
