Gate Dimensional Errors

This section describes the various gate dimensional errors that can occur with the CubiScan 125.
For dimensional errors relating to the ultrasound sensors, see
on page 8.

Inconsistent Measurement Readings

Complete the following steps if you are receiving inconsistent measurement readings.
1. If there are any invalid yellow shapes in your measurement results, refer to
Shapes in Measurement Results" on page
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 125 reports roughly the same measurements each
time, the CubiScan 125 is measuring accurately. If the CubiScan 125 is not reporting
consistent readings, continue on to the next step.
4. If LEDs are incorrectly firing when the gate moves you may need to replace the gate cables.
The gate cables that travel through the gate hinge may become worn over time.
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
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 125
finds the top and bottom limits and automatically picks the best values. Make sure you move
the gate to the middle of the CubiScan 125 when you run this test. You must save your settings
to retain any changes.
