User manual

Use the Enable Frequency Selection option to test the available frequency settings and
determine the best frequency. The range of frequency settings and the default setting de-
pends on your touch controller. You can set a new operating frequency, and then check the
performance of the touch sensor at that frequency setting.
Be aware that if you choose Restore Factory Settings → Controller from the Tools tab,
you will change the Touch Screen Frequency to the factory default setting. You may need
to redo the Touch Screen Frequency at this time
Touch Screen Frequency Procedure
From the Tools tab, you can choose the Advanced Options button. From the Advanced
Options dialog, select Enable Frequency Selection to activate this option on the controller
tab if you are using a capacitive EX based controller.
In the Touch Screen Frequency box, you will see a pull down list of several frequency
options. In general, the highest possible frequency will provide the best results. Once you
change the frequency, do not touch the sensor for approximately 30 seconds. Touch will
return when the frequency has been changed. Test to see if you are satisfied.
On a pen controller system, you have the option to change the frequency for both your finger
and the pen if you are using Pen/Finger mode.
Testing the Newly Selected Frequency
Any time you adjust the Touch Screen Frequency you should test how the touch sensor is
working and verify you are satisfied with the operation of the touch sensor.
Test the sensor by touching in several places and sliding your finger around the sensor.The
cursor should hold steady and smooth. If you see erratic or jittery cursor movement, readjust
the Touch Screen Frequency.
Adjust the frequency until your touch test produces acceptable results. A good test is to go
to the Draw program and hold your finger steady on the sensor. If the resulting pattern is a
crisp and clear single dot, you should have a good frequency.
It is recommended that you recalibrate the touch sensor after you run the Touch Screen
Frequency option.
