Customizing Data Resolution and the AutoScale Feature
Use the
buttons to increase or decrease the concentration (in ppm or ppb) that is plotted on the
y-axis of the chart. If you continue to press the
buttons, the Sensor cycles through the available
ranges until the
AutoScale
feature starts. The available ranges are as follows: 1, 2, 5, 10, 20, 50,
100, 200, and 500 ppb; and 1 and 2 ppm. The TOC trend is calculated from data collected in
15-second intervals. With the
AutoScale
feature, The CheckPoint automatically sets the chart to
show the maximum concentration level for the current data set. When AutoScale is active, the
AutoScale Arrows display on the right side of the screen. When AutoScale is not active, the
AutoScale Arrows do not display.
