(6) Temperature curve
In the main interface, click the curve display button,
interface displays as follows:
6-2 The average power curve
2.6.1 Temperature recording curve is as follows:
Temperature curve automatically updates every one hour,
and the curve record can be stored for 60 days;
Start from the latest curve saved time, if power is off and
curve data collecting time is less than one hour, the data
in this period will not be saved;
