During Recording
During normal operation the display shows the most recently recorded temperature. The
current time is also displayed in 24-hour format. A tick symbol is shown as long as no
alarm event has occurred.
Temperatures can be shown in Celsius (as on the left) or Fahrenheit (as on the right).

It is set during configuration.

In this example, the most recently recorded temperature
is above the primary upper alarm threshold, but below a
secondary threshold and no alarm was triggered:
