Setting The Absolute Height; Setting The Threshold Value For Sunshine Duration; Multiple Value Display; End - La Crosse Technology WS-2510 Operating Instructions Manual

The new calibration factor is derived from the following simple calculation:
New calibration factor =
The old calibration factor (e.g. the current valid value) can be found in the "Rain-
fall per rocker" input field. If necessary you can also enter the new calibration
value in this input field.

Setting the absolute height

This input field in the "air pressure" menu tab allows the height of the current
location of the air pressure sensor above sea level to be entered. This means
that the air pressure display is adapted to the current location by means of a
correction factor. As a result of this, the relative air pressure is displayed.

Setting the threshold value for sunshine duration

The set-up field in the "Sunshine duration" tab enables the brightness threshold
to be set, above which the light striking the brightness sensor is to be interpreted
as sunshine. This threshold can be set between 2 and 99 klux and is set in the
factory to 20 klux.
A value above the value set is judged to signify sunshine.
This value corresponds to the threshold value generally used in meteorology for
registering the hours of sunshine.
The sunshine duration transmitted from the brightness sensor is used if the
threshold level is 20 klx. For all other values, the program calculates the sunshine
duration from the brightness. The disadvantage of this is that breaks in reception
or large interface storage intervals can falsify the result. This does not occur
when the sunshine duration transmitted from the sensor is evaluated.

Multiple value display

For the temperature/humidity sensors and the wind sensor, the relevant menu
tab will offer you the option of having either the main value (temperature/wind
strength) or both of the generated values (temperature/humidity or wind strength/
wind direction) displayed. To see the relevant secondary value, click on the
corresponding set-up field.
