The wind speed unit can be set as mph (mile per hour), km/h (Kilometer per hour), or m/s
(meter per second). The default unit is mph.
1. Use the + or MIN/MAX key to toggle between the unit “mph”, “km/h”, or “m/s”
2. Confirm with the SET key and enter the RAINFALL UNIT SETTING.
RAINFALL UNIT SETTING (OPTIONAL)
Note: the rain unit setting is only available if there is a rain sensor. Skip this setting by
pressing the SET key again to enter the Relative Air Pressure Unit Setting.
The total rainfall unit can be set as inch or mm. The default unit is inch.
1. Use the + or MIN/MAX key to toggle between the unit “mm” or “Inch”
2. Confirm the unit with the SET key and enter the RELATIVE AIR PRESSURE UNIT
SETTING
RELATIVE AIR PRESSURE UNIT SETTING
The relative air pressure can be set as hPa of inHg. The default unit is inHg.
1. Use the + or MIN/MAX key to toggle between the unit “hPa" or “inHg”
2. Confirm the unit with the SET key and enter the RELATIVE PRESSURE
REFERENCE VALUE SETTING.
RELATIVE PRESSURE REFERENCE VALUE SETTING
Note:
The default reference pressure value of the barometer is 29.91inHg (1013 hPa) when
batteries are first inserted. For an exact measurement, it is necessary to first adjust
the barometer to your local relative air pressure (related to elevation above sea
level). Ask for the current atmospheric pressure of your home area (Local weather service,
www, calibrated instruments in public buildings, airport).

The relative air pressure can be manually set to another value within the range of 27.14 to
31.90 inHg (919 to 1080 hPa) for a better reference.
1. The current relative pressure value will start flashing
2. Use the + or MIN/MAX key to increase or decrease the value. Keep holding the key
will allow the value to increase faster.
3. Confirm with the SET key and enter the WEATHER TENDENCY THRESHOLD
VALUE SETTING.
Note:
This calibration facility is useful for those users living at various elevations above sea level,
but wanting their air pressure display to be based on sea level elevation.
WEATHER TENDENCY THRESHOLD VALUE SETTING
You may select a definite switching sensitivity value, .06, .09, or .12 inHg (2-4 hPa) for the
change in the display of weather icons. This represents the "sensitivity" of the weather
forecast (the smaller the value selected, the more sensitive the weather forecast). The
default value is 0.09 inHg (3 hPa).
1. The threshold value will start flashing
2. Use the + or MIN/MAX key to select the value.
3. Confirm with the SET key and enter the STORM WARNING THRESHOLD VALUE
SETTING.
