Analog Data Display Screen
The Analog Data Display Screen is laid out very much like the Main Display
Screen. It has the same top and bottom banners of information. Instead of showing
particle count information in the data area, it shows data from the analog devices
connected to the unit. For example, the Temperature/Relative Humidity Sensor
would show temperature and relative humidity values.
To view the Analog Data Display Screen, press the softkey to the right of the
Analog Data display icon (fourth icon). A sample Analog Data display screen
is shown below.
Analog Data Display Layout —
The Analog Data Display Screen is divided
into the following areas:
•
Data Area
: When sampling is first started, no data is shown. As data is
generated, it is displayed. When the sample is complete, these results will remain
on display until the next sample is started. At that time, the columns will reset to
zero in preparation for the next set of analog data.
