9.2 Low battery display
9.3 Power ON/OFF
In Wind speed mode, the meter will automatically switch OFF when no key is pressed and the wind
speed is zero for 30 minutes to save battery life.
In Altitude display mode, the meter will automatically switch OFF when no key is pressed for 24hours
to save battery life.

The unit will detect the voltage of battery just after power on. In normal
mode, the unit detects low battery every 10 minute. In power off
mode do not detect it, if the battery voltage is low, the icon
be displayed.
Press and hold down the "SET" key for 4 seconds to switch the unit
ON or OFF. In power off mode the unit will sleep and do not detect
the wind speed and temperature data, all the history data will be
cleared too.
Accuracy is defined as the ability of a measurement to match the
actual value of the quantity being measured.
The Beaufort Scale is an empirical measure for describing wind
speed based mainly on observed sea conditions (on land it is
categorized by the physical effects it has on vegetation and
structures). Its full name is the Beaufort Wind Force Scale.
