Zone Setup Screen #2 Trend Screen
The trend graph opens with the cursor located over the most recent data point. Use the LEFT/RIGHT cursor
keys to move the cursor to different data points. Holding a key down will cause the cursor to move rapidly
across the screen. As you move the cursor position, the date and time of that reading, along with the PPM
value, are displayed at the top of the screen above the graph. The trend graph is automatically scaled to
accommodate the largest PPM value displayed. The ZOOM OUT and ZOOM IN options allow you to adjust
the vertical scale of the graph.
The trend data is stored on a first-in, first-out basis. After 100 trend values have been stored the 101
st
value
will replace the first value stored. Therefore, in normal operation, when entering trend mode the cursor will be
located at the most recent data point. The data points to the left of the initial cursor location will be the next
most recent. The data point to the right will be the oldest data point in the buffer and will be over written by
the next data point.
The Trend Data Log can be reset by pressing a combination of the ENTER and RIGHT arrow buttons while
viewing the log.
When finished, press the ESC key to revert to the previous screen. (or system screen?)
