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 flash.
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.
