1. If there are any invalid yellow shapes in your measurement results, refer to
Shapes in Measurement Results” on page 6
. If there are no invalid yellow shapes in your
measurement results, continue on to step 2.
2. Does the object you are measuring have a rigid shape? If the object that you are measuring
does not have a rigid, stable shape then it is able to change shape. Measurements taken after
an object has changed shape will reflect the current state of that object.
3. Measure the calibration cube in different orientations multiple times to check for
dimensioning accuracy. If the CubiScan 25 reports roughly the same measurements each
time, the CubiScan 25 is measuring accurately. If the CubiScan 25 is not reporting consistent
readings, continue on to the next step.
4. If the gate movement isn’t smooth, the carriage assemblies that control gate movement may
need to be adjusted or replaced. For instructions on how to do this, see
Carriage Assemblies” on page 48
5. If, after completing the above steps, you are still receiving inconsistent measurement
readings, please contact Quantronix Technical Assistance at +1 801-451-7000.
Incorrect Height Measurement
Complete the following steps if you are receiving incorrect height measurements.
1. Clean all four gate filters with a clean, damp (if needed), microfiber cloth. Use water to
dampen the cloth;
do not clean the gate filters with a solvent as this could cause
damage
.
2. Make sure that all the controller box cables are securely attached.
3. Go to
Menu > Diagnostics > Gate
. On the second and fourth gate diagnostic screens, the
threshold and sensitivity values are listed for the width and height. The threshold values
should be between 550 and 750. The sensitivity values should be 100. If your values are
incorrect, go to the fifteenth gate diagnostics screen. From this screen you can run an
automatic threshold setting test for the LED beams. When this test is run the CubiScan 25
finds the top and bottom limits and automatically picks the best values. Make sure you move
the gate to the middle of the CubiScan 25 when you run this test. You must save your settings
to retain any changes.
4. Go to
Menu > Diagnostics > Gate
. This screen displays the current status of the LED beams.
Move the gate to the center of the glass platform and clear the platform of all objects. If the
LED beam bars show yellow, continue on to the next step.
5. Go to
Menu < Diagnostics > Gate (16/16)
. From this screen, you can run a masking test to mask
LEDs that may be malfunctioning. You should only run this test if 3 or less of the LEDs are
not working.
Do not
run the masking test if a large amount of yellow is displayed on the LED
beam bars. If too many LEDs are masked, the CubiScan 25 will not be able to measure
objects. To run the masking test, start with the gate in the home position (right side) and
