Touch Sense 1 Development Board User’s Guide
Guard Band and Trip Level parameters are easily changed by sliding their associated
pointers up and down the gauge. The Guard Band provides a range of raw data values
that will be included into the averaging algorithm of the demonstration software. Any
raw data value below the Guard Band is not included. More information on software
algorithms and other mTouch Technology related topics can be found in the mTouch
User’s Guide on the accompanying CD-ROM following installation of the mTouch
SDK).

Alternately, gauges can be configured using the Setup window. Click on the gauge
associated with Key ‘0’ to open the Gauge Setup window shown in Figure 2-8.
FIGURE 2-8:
The Setup window allows customization of a particular gauge by numerically adjusting
parameters such as Guard Band and Trip Level. Additionally, auxiliary pointers can be
added to the gauge for other user determined references. The scale section of the
window provides individual gauge scaling of both Upper (UL) and Lower Limits (LL) or
by using the AutoScale button.
2.4.9
Click on the Chart button within the Setup window. The Chart window shown in
Figure 2-9 should now be open.
