• Click RUN to test the program,

observing that the Laser Proﬁle

window opens.

The laser uses the speciﬁed laser program to measure whatever is under

the camera, whether it is a dispensed ﬂuid or a workpiece surface. For

correct laser measurement results, the laser program must be tailored to

the characteristics (transparency, thickness, etc.) of the ﬂuid or workpiece

being measured.

NOTES:

- For details on the Laser Proﬁle window, refer to “Laser Proﬁle Window

Fields” on page67.

- To use the Laser Proﬁle window to check whether laser measurements

are within a speciﬁed range of threshold values, refer to “To Check

Laser Measurements Against Threshold Values” on page67.

• Click the red X to close the Laser

Proﬁle window.

• Double-click the LASER READ-OUT

ﬁeld to re-open the Laser Proﬁle

window.

9 • Optional: Repeat steps 2–5 and enter

another laser program selection in the

Laser Program command window;

also try different workpieces to test

other laser program settings.

• Go to D:\Laser Proﬁle to see

the saved graph and data point

(measurement data) ﬁles. Graphs and

data points are saved automatically

after every run cycle.

NOTES:

• All *.CSV and *.JPEG ﬁles are named with the date and time using the

following format:

- YYYYMMDD_HrMinSecs.CSV

- YYYYMMDD_HrMinSecs.JPEG

• Every subsequent laser program will have an underscore and a number.

For example:

YYYYMMDD_HrMinSecs_1.CSV, YYYYMMDD_HrMinSecs_1.JPEG

YYYYMMDD_HrMinSecs_2.CSV, YYYYMMDD_HrMinSecs_2.JPEG

To Check Laser Measurements Against Threshold Values

When the laser is measuring and recording, you can use the Laser Proﬁle window to specify Max and Min threshold

(tolerance) values and to select the alert option to appear when a measurement is outside of the speciﬁed Max and /

or Min thresholds.

# Click Step Reference Image

• Ensure that the following values are

properly set:

- Y MAX and Y MIN: The maximum

and minimum values for the vertical

axes (in mm).

- X SIZE: The number of laser

readings to show in the graph (the

minimum is 101).

the graph

Graph

Sets the

maximum and

for the vertical

axes (in mm)

Shows the record

number associated with

the laser program that

is running (for example,

if the robot dispense

program speciﬁes

laser programs 1 and

2 (in that order), then

Record 0 is tied to

laser program 1 and

Record 1 is tied to laser

program 2)

Sets maximum and

minimum threshold

(tolerance) values for the

measurement results and,

if enabled by checking Max

and / or Min, speciﬁes the

desired system response

(Skip, Stop, or Pause)

when a measured value is

out of range. Refer to “To

Check Laser Measurements

Against Threshold Values”

on page67 for details.

Sets the number of

(minimum is 101)

Laser Profile Window Fields

If Skip Error Value is

checked, then the

graph excludes any

measurements outside of

Y Max and Y Min

XSize value (200, in this

example)

Shows the number of laser

readings that will be in the

*.CSV ﬁle. For example, if

recording is stopped at 60,

then there will be 60 laser

readings inside the *.CSV

ﬁle.

NOTE: Recording can continue

past the X Size. For example, if

the X Size is set to 200, but you

have 300 laser readings, only the

ﬁrst 200 readings are shown on

the graph. You can change the

X Size value during or after laser

measurement.
