Chapter 4 Using the Microcal Diagnostic Utility 97
If you are using a TouchPen controller, when you run Noise Check
you are asked whether you want to set the frequency for the pen or
finger. If you need to set the frequency for both touch methods, you
can run Noise Check for each touch method.
Using Automatic Frequency Adjust
Use the Noise Check option to test the available frequency levels and
determine the best frequency based on the amount of monitor noise the
touchscreen is receiving. You can set a new operating frequency, and
then check the behavior and performance of the touchscreen at that
frequency level.
Testing Frequency Levels and Selecting a New Frequency
To test operating frequencies and set a new frequency:
1. Choose Noise Check from the Microcal Main menu or Diagnostics
menu.
If you are using a TouchPen controller, a dialog box appears
asking if you want to adjust the frequency for pen or finger.
Specify the touch method for which you want to adjust the
frequency.
You may see an initializing screen as Microcal does a preliminary
check of the frequency levels.
The Set Frequency dialog box appears.
