Graphical Data Record
The Graphical Data Record charts the average temperature from the return air temperature sensor
(see Figure 10). The temperature scales can be changed to expand or compress the data. The time
scale also can be altered to any of several selectable values. Changing the time scale eliminates all
previous graphical data and the unit will begin recording new data.
