Using the Center Button for LaserC Setup

On systems with Laser C, the Laser Detect Setup window has a Center button that can be used for more precise

laser calibration. Using the Center button is optional, but is recommended to obtain the most accurate calibration.

Follow these steps to use the Center button during Laser C setup.

PREREQUISITES

• Move the laser to the centering hole located on

the tip detector.

2 • Observe the laser readout value. If the laser

readout shows -99.999, the laser is successfully

passing through the hole. If not, the laser is not

precisely centered.

• Click CENTER next to Set Laser.

The laser moves in two directions (left to right,

then north to south) to calibrate itself and then

moves to the center of the hole.

• Click SET LASER.

4 • Jog the camera to center the crosshairs over

the centering hole located on the tip detector.

• Click SET CAMERA.

The laser-to-camera offset is now precisely

calibrated.

Using Image Threshold

Image Threshold allows you to view changes to a mark image as you make adjustments. This feature can be used

alone or in tandem with an Add New Arrow function. Nordson EFD recommends ﬁrst using Image Threshold before

using some of the Arrow Type functions, so that you can view the changes to the image on the screen.

NOTE: A quicker alternative to using Image Threshold is to use the Threshold slider inside each Arrow Type dialog

box. If you want to use the quicker method, do not enable Image Threshold.
