the scale, up to 20 ppm. Note that the minimum range of data visible (down to 0.100 ppm) depends
on the current data being graphed. For example, if the current data is 3.486 ppm, the user may use
the up key to zoom in to the 5 ppm range, but cannot zoom in to a narrower 2 ppm range.
The graph begins on the left side and moves with the vertical line towards the right as more data
points are added. Once the time line reaches the right side of the display, the data will be
compressed to the far left. The graph refreshes every 1 hour.
The time scale relates directly to the vertical position line. In other words, the line moves to the
right as new data points are added. Every time a data point is added, the time scale is incremented.
For time under 10 minutes, the graph is updating almost every second.
The bottom of the display shows the uptime of the F-900 and current battery level.
