3. Click Start to begin plotting the particulate level. Click the button several times to zoom in. Click the button to zoom out.
4. As time passes, the average particulate level, the maximum and minimum particulate level, and the alarm thresholds will be
plotted on the graph. The average signal is pink and the maximum is purple.
Note: The trend graph control can be resized by moving the cursor to the black-gray border just above the Date menu.
When the cursor changes, click to drag and resize.
5. The signals that are displayed and the update rate may be customized via the Settings button. The minimum update rate is
5 seconds.
The Threshold Scaling group can be used to modify the behavior of the Y axis. The Dynamically fit the data option will au-
tomatically increase the range of the Y axis when the particulate level increases. When the Maximum Obscuration option is
selected, the range of the Y axis will remain fixed.
Historical Trend Graph
The FAAST detector records the daily minimum, average, and maximum particulate level for the last year of operation. This informa-
tion can be retrieved and plotted on a graph using the Stored Trend Mode. To retrieve the stored particulate data, follow these steps:
1. Connect to the detector and switch to the Monitoring View. For instructions, see the previous section.
2. From the Mimic View, click the blue View Trend Graph text to open the trend graph. The trend graph opens below the Mimic View.
