Operation
Notice
When moving the meter from one atmosphere with extreme temperature
or humidity to another, you need to wait for it to stabilize. Press to
start the meter and read the measurements displayed by °C or °F. Press
to switch.
Dew-point & Wet-bulb
When starting the meter, the ambient temperature appears on the
screen. To obtain DP, press a first time and press for a second
time, WB is switched. Press a third time, to get the ambient
temperature back. A corresponding signal will be shown on the screen
indicating DP and WB.
Holding
Hold the button Press to freeze the current reading, and stop the
meter from displaying the measurements. When the HOLD function is
