Figure 2: Batteries or USB cord
(1) Unfold the desk stand and place it 5 to 10 feet away from the outdoor
sensor.
(2) Remove the battery door and insert 2 AA Alkaline batteries. Then plug
in USB cord for normal operation. Please note the primary use of
battery is for power cut back up purpose only, and always the console
need to be powered via USB power.
(3) Wait several minutes for the remote sensors to synchronize with the
display console.
(4) During normal operation, console will generate heat and cause
temperature rising. To prevent this heat up, the temperature and
humidity sensor is located at the foldable probe ends. To achieve
maximum accuracy reading, please unfold the probe and make sure
the sensor is further away from the main console body.
4.1 Initial Display Console Set Up
Upon power up the display console:
The unit will show sensor frequency under the wind direction graph and
software version number 2 seconds.
Then all segments of the LCD will be on for 3 seconds: check all LCD
segments are displayed correctly. After this, the unit will start to register
sensors for 3 minutes.

5.3 Barometric Pressure Display
5.3.1 Viewing Absolute vs. Relative Pressure
Press and hold [RAIN/PRE] for two seconds switch between Rain and
Pressure. While in Pressure mode Press [RAIN/PRE] to switch between
absolute and relative pressure
Absolute pressure is the measured atmospheric pressure, and is a function
of altitude, and to a lesser extent, changes in weather conditions.
Absolute pressure is not corrected to sea-level conditions.
Relative pressure is corrected to sea-level conditions. For further
discussion of relative pressure and calibration, reference Section 0.
5.3.2 Rate of Change of Pressure Graph
The rate of change of pressure graphic is shown to the left of the weather
forecast icons and signifies the difference between the daily average
pressure and the 30-day average (in hPa).
Figure 7
5.3.3 Relative Pressure Calibration Discussion
The calibration can be realized on ECOWITT app by going to “sensor”
page, and you can find the console of WN1980 to start with. To compare

13
pressure conditions from one location to another, meteorologists correct
pressure to sea-level conditions. Because the air pressure decreases as you
rise in altitude, the sea-level corrected pressure (the pressure your location
would be at if located at sea-level) is generally higher than your measured
pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude
of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 inHg (1013 mb). This is the
average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered high
pressure and relative pressure measurements less than 29.92 inHg are
considered low pressure.
To determine the relative pressure for your location, locate an official
reporting station near you (the internet is the best source for real time
barometer conditions, such as Weather.com or Wunderground.com), and
set your weather station to match the official reporting station.
5.4 Rain Display
5.4.1 Rain Increments of Measure
Press and hold [RAIN/PRE] for two seconds switch between Rain and
Pressure. While in Rain mode press [RAIN/PRE] button to switch between
Rain Rate (in/hr), Rain Event, Rain Hourly, Daily Rain, Weekly Rain,
Monthly Rain and Yearly Rain.
5.4.2 Increments of Rain Definitions
•Rain rate or hourly rain is defined as the last 10 minutes of rainfall
sum total and multiplied by six (10 minutes x 6 = 1 hour). This is also
referred to as instantaneous rain per hour.
•Rain event is defined as continuous rain, and resets to zero if rainfall
accumulation is less than 1 mm (0.039 in) in a 24-hour period.
•Daily Rain is defined as the rainfall since midnight (00:00).
•Weekly Rain is defined as the calendar week total and resets on

14
Sunday morning at midnight (Sunday thru Saturday).
•Monthly Rain is defined as the calendar month total and resets on the
first day of the Month.
•Yearly Rain is defined as the calendar year i.e. January 1- December

5.5 Wind Display
Press the [WIND -] button to switch between average wind speed and,
wind gust.
Press and hold the [WIND -] button for two seconds to switch the wind
direction to display in degrees or in letters.
•Wind speed is defined as the average wind speed in the 16 second
update period.
•Wind gust is defined as the peak wind speed in the 16 second update
period.
5.6 Temperature Display
If temperature is lower than minimum range, the temperature field will
display dashes (--.-).
If temperature is higher than maximum range, the temperature field will
display dashes (--.-).
5.6.1 Wind Chill, Dew Point and Heat Index Display
Press the [TEMP] button to switch between Outdoor Temperature, Wind
Chill, Dew Point, Heat Index.
The device supports up to 8 additional thermo-hygrometer sensors (WH31).
