the same time, please note that the condition needed in each
measurement is different to get the best result. When measure
air temperature, you’d better take your watch from your wrist
to minimize the affection to the measurement result by your
body heat. However, when measure height, you’d better wear
your watch on your wrist. This can improve the accuracy of the
measurement by keeping constant watch temperature.
The following actions need to be take rst before measuring
height or temperature:
When height measurement is priority, please wear your watch
on your wrist or put it in a place where your watch temperature
can be kept constant. When air temperature measurement is
priority, please take your watch off from your wrist and hang it
on your handbag or any place not exposed to direct sunshine.
Please note that when take your watch from your wrist, the
measurement value of air pressure sensor will be affected
temporarily. The air pressure sensor in this watch can be used
to measure the change of air pressure for your reference to
forecast weather. This sensor is not a precise device for ofcial
weather forecast.The sudden change of air temperature can
affect the measurement result of the sensor. Air temperature
measurement can be affected by body temperature (when you
wear your watch), direct sunlight and humidity. To get a more
exact air temperature measurement, please take your watch
from your wrist, put it in a place that is not exposed to direct
sunlight or drafty conditions, and wipe the watch case dry. It
will take 20 to 30 minutes for the watch case to reach actual
environmental temperature.
The work principle of barometer:
The air pressure reects the change of atmosphere. Through
observing the atmosphere change, you can forecast the weather
in a rational veracity range. Atmosphere pressure going up
indicates ne weather, but atmosphere pressure going down
indicates the weather is turning into bad.
The atmosphere pressure value published in newspaper or
reported in television weather forecast programmer is the
measurement value after being modied to the value at sea
level (elevation is 0 m).
Importance:
In order to restart to correct digital compass automatically, the
watch must be turned two circles ( put the watch horizontal,
turn clockwise or counter clockwise) when using the compass
function the rst time after you replace the battery. The value
of air pressure, height, temperature will be set factory default
value automatically. Please do not correct the related value at
will when there is no high-precision air pressure, temperature
or compass as the correction reference point. Please conrm
to use (PDEF) factory default value according to operating
manual if operating wrong cause the value of air pressure or
height is wrong when in use.
