@ shows the number of data stored in the current data group.
@ In the first line, when in "Save" mode, the serial number is displayed. In the
"real-time" mode, the time displayed is the real-time display time.
@ The second line is the numerical value of illuminance. What follows is the
unit at the time of saving. If the unit is changed during use, it will also be
displayed here.
@ The third line is the temperature value/pattern (Note: The "temperature
value" is displayed in real time, "Mode" is displayed in storage state).
