Display functions
Currently measured values
During normal operation the
relative air humidity
in
[%RH]
is displayed alternating to
the
temperature
in
[°C]
or
[°F]
.
display relative air humidity
display temperature
Min/Max Value Memory
watch Min values (Lo): press ‘down‘(2) shortly once
display changes between ‘Lo‘ and Min values
watch Max values (Hi): press ‘up‘(3) shortly once
display changes between ‘Hi‘ and Max values
restore current values: press ‘down‘(2) or ’up’(3) once again current values are displayed
clear Min-values:
press ‘down’(2) for 2 seconds
Min values are cleared. The display shows shortly ‘CLr‘.
clear Max-values:
press ‘up’(3) for 2 seconds
Max values are cleared. The display shows shortly ‘CLr‘.
After 10 seconds the currently measured values will be displayed again.
