Rainfall Measurement; Air Pressure Measurement - La Crosse Technology WS-2510 Operating Instructions Manual

4. Here, the "Graph" symbol
field. It only appears if it has previously been selected (see 3.2.6.:"History"). The trend can be displayed in km/h, m/s,
mph or knots. However, if Beaufort or degrees have been chosen for the main display, any trend available will be
shown in km/h.
Key functions (Allocation of touch screen fields, see page 9)
- Touch screen field 7 switches over between the units for wind speed and the display of numerical wind direction.
The switching sequence is: km/h, m/s, mph, knots, Beaufort, numerical value of wind direction in degrees.
3.2.3. Rainfall measurement (fields 8/9)
The display field for the rainfall measurement is situated in the middle at the top.
Here, the amount of rain collected in the rainfall sensor and the current rainfall (rainfall in the last quarter of an hour) are
displayed.

1. The rainfall is either displayed as a total ("total"; since the last deletion), the last hour
("1h"), the last day ("24h") or the current day ("current 24h").
The following particular features should be noted:
The rainfall for the "last hour " is always calculated on the half hour, e.g. between 14:30 and 15:30.
The rainfall for the "last day" is always calculated at 7:30.
The rainfall for the "current hour/day" is calculated from the accumulated stored values for the "last hour/day".
As a result of internal checking functions, the display of the rainfall is delayed by between 3 and 12 minutes.
2. Umbrella symbol: shows current rain, i.e. if the rainfall sensor has reported an amount of rain within the last 15
minutes, which is above the trigger point for the rainfall sensor.
3. Here, the "Graph " symbol
only appears if it has previously been selected (see 3.2.6.: "History").
Key functions (Allocation of touch screen fields, see page 9)
- Touch screen fields 8 and 9 switch over the display mode.
The switching sequence is:
Total, current hour, last hour, current day, last day.
- If touch screen field 26 ("RESET") is pressed briefly, the point in time at which the total rainfall data were last deleted
will be displayed in the date and time field.
- If touch screen field 26 ("RESET") is pressed for 3 seconds, the total rainfall value will be deleted.
3.2.4. Air pressure measurement (fields 10/11)
The display field for the air pressure measurement is situated in the middle at the top right hand side ("AIR PRESSURE").
Here, the current air pressure at the location of the weather station is displayed with one of three possible units.

1. Depending on the setting in the configuration mode, the air pressure is displayed in hPa, mmHg or inHg.
2. Either the relative air pressure (value corrected for height, see corresponding setting in configuration mode and the
explanation in the section "Explanation of terms") or the absolute air pressure (the uncorrected output value from the
sensor, right hand diagram) can be displayed.
