Large Amounts of Yellow
Complete the following steps to eliminate large amounts of yellow that appear in measurement
results.
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. Check the light on the transmitter or receive boards. The light is located about halfway up the
board on the left side. If this light is not lit, the board is not receiving power.
4. 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.
5. 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, please contact Quantronix Technical Assistance at +1 801-451-
7000.
Gate Movement Errors
This section describes the various gate movement errors that can occur with the CubiScan 25.
Refer to the following sections for more information.
Gate Cursor Not Moving
Complete the following steps if the green gate cursor does not follow the gate’s movements.
1. Make sure that the green LED encoder light is lit.
2. Check the encoder cable and make sure it is securely attached at both ends of the cable. If
doing this does not correct the problem, continue on to step 3.
3. Check the encoder magnetic strip and see if it is visibly damaged. Contact Quantronix at +1
801-451-7000 if you need a replacement part.
4. Go to
Menu > Diagnostics > Encdr
. The encoder value should read
0000
when the gate is in the
home position. Move the gate all the way to the left and back into the home position. If the
