If there are measurement channels on one socket
(humidity and temperature), the humidity value is dis-
played in the first line and the temperature value in
the second line. Otherwise only the first line will be
used.
Example:
Logger 171-1
- Logger is currently measuring
- The internal temperature probe has a measured
value of 18.0 °C
