AUTO OFF FUNCTION
When you switch the device on, it shows the current ambient
temperature in °C on the display. To display the value in °F, press
the „Unit“ button. By pressing the „Mode“ button, you can get the
device to display the highest (MAX), lowest (MIN), average (AVG)
or difference value (DIF) in addition to the current measured value.
As its name suggests, the „HOLD“ button enables you to hold the
current measured value.

When you switch the device on, the „AUTO OFF FUNCTION“ is activated automatically. After 20 minutes,
the device switches off automatically unless one of the buttons is pressed. To activate or deactivate the
device‘s „AUTO OFF FUNCTION“, press the „SET“ button while pressing and holding down the „ON/OFF“
button. For optimum measurements, please wait approximately 15 minutes after switching on the measu-
ring device so that it has time to adapt to the new ambient conditions in a particular room.
Relative humidity may be de Ö ned as the ratio between the air‘s
current water vapour content and the maximum that it can contain
at the same temperature and constant pressure. Hot air can hold
more water vapour than cold air. At 100% relative humidity, the
saturation point has been reached and the air cannot hold any more
water vapour.
Press the „Temp/%rH“ until a measured value in % relative humidity
(%RH) appears on the display. By pressing the „Mode“ button,
you can get the device to display the highest (MAX), lowest (MIN),
average (AVG) or difference value (DIF) in addition to the current
measured value. As its name suggests, the „HOLD“ button enables
you to hold the current measured value.

In the event of rapid temperature × uctuations (± 1°C), the sensor needs to adapt to the new condi-
tions. Consequently, it takes a certain amount of time for a stable value to be established.
