Owner’s Instructions SKYWATCH ® You have just acquired a high precision instrument, manufactured using the most up-to-date technology. The Skywatch was designed to handle intense use and extreme conditions. Please take the time to carefully read your instructions so as to understand all the great features this unit has to offer. 123 Buttons Uses : Turn your on by pushing either the wind or mode button. Push the wind button to choose between maximum or average wind speed.
Temperature in Celcius and Fahrenheit degree Changing of temperature unit (ºC and ºF) Minimum and Maximum Temperatures : Minimum and Maximum temperatures are permanently displayed. Extreme values will flash on the bargraph. When your instrument is on standby, temperature is measured every thirty (30) minutes, allowing a recording of the extreme values, even when the instrument is turned off. Extreme temperature values can be deleted by pressing both the wind and mode buttons simultaneously.
The pressure can be influenced by 3 main factors: 1. Altitude. Pressure decreases with altitude. In similar meteorological conditions, if pressure is 1013 hPa at the sea level, it will be only 977 hPa at 300m or 794 hPa at 2,000 m. 2. Meteorological conditions. Atmospheric pressure changes according to the weather. During nice weather, pressure at the sea level can reach 1050 hPa and if the weather gets bad, it can go down to 980 hPa. 3. The wind. The wind can exert a pressure on objects that it hits.
Calibration: Calibration can be done only if the instrument is set in altitude mode. To enter calibration mode, both mode and wind button need to be pushed at the same time. All other information will disappear from the LCD. In this mode, the mode button increases the altitude and the wind button decreases it. Once the reference altitude has been correctly entered, you can leave the calibration mode by pressing both buttons mode and wind at the same time.
Dew point : Dew point is calculated by mixing the humidity rate and current temperature. It indicates at what temperature condensation will appear. Dew point can be selected by pushing the mode button. It is then indicated in ˚C or ˚F in the lower corner of the display with the symbol Dew point Current Wind Speed : The impeller at the top is the wind sensor. For accurate measurements, it is necessary for the ball propeller to be wide opened (you can pivot it) and to be aligned with the axis of the wind.
with a AV symbol for average wind speed and MAX symbol for maximum wind speed. Maximum wind speed can be deleted by pressing the wind and mode buttons simultaneously. Standby : The instrument turns itself to standby after 3 minutes without touching any buttons. In the stand by mode, only the clock is displayed. A pressure on a button and the instrument turns on. Clock Timer: Standby mode The clock is displayed only in standby mode. Press and hold the middle button for 1-2 seconds to set the clock.
Batteries : The is powered by a 3V type CR2032 Lithium battery,. The features an extra battery that allows for convenient replacement at any time and place. Battery replacement : Unscrew the cover on the back of the instrument. Insert the battery on the bottom, positive side (+) facing you. A second replacement battery HAS to be put on the top of first battery and HAS to be inserted with negative side (-) facing you - the + side against the + side. Screw the cover back with the 2 screws M2,5 x 5.
