During the sampling run, the PDM will run automatically until the sample
cycle ends. After 30 seconds of inactivity at the end of the sample run, the
PDM will turn off its LED display. Press the "A" button to reactivate the
LED display. This action will display the Sampling Complete - Screen #1.

Each bar represents the previous 30-minute, averaged mass concentration
value. "The 1.0" denotes the highest mass concentration value measured;
the "0.0" represents the lowest mass concentration value measures. A new
bar is added to the graph every 30 minutes, with the width of each bar
representing a 30 minute time period. When there are bars displayed across
the entire screen and a new bar is added, the new bar will display at the far
right side of the screen, and the previously displayed bars will move to the
left.
