Wind Direction And Wind Speed Measurement; Rainfall Measurement - Technoline WS 2816 Manual De Instrucciones

indicate the current air pressure. The varying height of bars inn other columns on the
graph indicate a relative change in air pressure up or down from the previous
measurement.
New pressure measurements are compared to previously recorded pressure
measurements. The pressure change is expressed by the difference between the
current ("0h") and the past readings in divisions of ±0.06 inHg or ±2 hPa. If the bars are
rising from left to right, this indicates that the weather is getting better due to an
increase in air pressure. If the bars are falling from left to right, this indicates that the
weather is expected to get worse due to a drop in air pressure.
At every full hour, the current air pressure is used as a basis for the display of a new
graph bar. The existing graph is then moved one column to the left.
Note: For accurate barometric pressure trend, the Weather Center should operate at
the same altitude. For example, it should not be moved. Should the unit be moved, for
instance from the ground to the second floor of the house, the readings for the next 48-
60 hours shall be discarded.
Note: The bar graph will scroll right to left regularly to prevent LCD burnout.

WIND DIRECTION AND WIND SPEED MEASUREMENT

 The current wind direction is indicated by a pointer on the outer circle of the
compass.
 The last 6 wind directions are displayed with pointers on the inner circle.
 The wind direction (abbreviation or degrees) is displayed in center of compass.
Press the SET key to toggle between Mode1 and Mode 2 of the display
Mode 1 displays the following wind data:
 Wind direction (shown on the compass scale of 16 divisions)
 Wind chill in C or F
 Wind speed in km/h, mph, bft, knots or m/s
Mode 2 displays the following wind data:
 Wind direction (shown on the compass scale of 16 divisions)
 Wind chill in C or F
 Wind gust in km/h, mph, bft, knots or m/s

RAINFALL MEASUREMENT

The 1hour, 24 hour, week, month or total rainfall measurement is displayed on the LCD,
in the unit of mm or inch.
Press the ▼DOWN ARROW to select the rainfall display from the following modes:
 Total rainfall - reset manually (see "RESET THE MIN/MAX WEATHER DATA")
 Last 1 hour rainfall – it shows the sum of last 15 entries of four minutes rainfall
 Last 24 hours rainfall - it shows the sum of last 24 entries of hourly rainfall
