"30" for another second.
The discharge temperature and environment temperature are displayed as four-digit values,
circularly displaying the higher two digits and the lower two digits. For example, if "01" and "15" are
alternately displayed, it indicates 115  C. If "nE", "00", and "28" are alternately displayed, it indicates
-28  C.
If a parameter is invalid for the unit, "00" is displayed.
