- When air pressure or height test is higher than test range, it shows HI, lower than test range, it shows Lo.
- The method of weather forecast detection as follows: weather condition is judged every hour (based on the change of atmospheric pressure in the first four hours). If the pressure value is rising gradually, the weather is improving, and if the pressure value is decreasing gradually, the weather is getting worse. Weather conditions are divided into 4 (from good to bad): sunny, cloudy, cloudy, rainy days.
- The range of atmospheric pressure test is 300~1100mbar or 8. 84~32. 44inHg
- The range of temperature test is -10~60℃ or 14~140℉
- The range of height test is -700~9000m or -2300~29529F
- Instructions for using digital compass
- This watch is equipped with a magnetic directional sensor to detect geomagnetism. It means that the north as shown in this watch is the magnetic arctic, which is slightly different from the true arctic. The magnetic arctic lies in the north of Canada and the magnetic pole in the south of Australia. Please note that with all magnetic compass measurements, the closer the magnetic poles to the Earth, the greater the difference between the magnetic North Pole and the true Arctic. Furthermore, It is also important to note that some maps are represented as true arctic (not magnetic arctic), so appropriate adjustments should be made in the use of such maps and watches.
- Location measurement
- When measure direction near a strong magnetic field, a huge error will be created. Thus the following objects shall be avoided when measuring direction: Permanent magnets (magnetic necklaces, etc. , metal blocks (iron doors, metal lockers, etc. ), high voltage wires, antennas, home appliances (TV, PC, washing machines, refrigerators, etc. )
- When in the train, ship or plane, etc. the direction value can not be measured correctly.
- The direction values cannot be correctly measured indoors, especially in buildings with many metals. This is because the metal structures in such buildings absorb magnetic force from electrical appliances, etc.
- Preservation
- If this watch is magnetized, the accuracy of the orientation sensor will be reduced.
- Therefore, this watch shall be kept in the vicinity of the magnet and any object which emits a strong magnetic force, including: Permanent magnets (magnetic necklaces, etc. ) and home appliances (TV, PC, washing machines, refrigerators, etc. )
- If you suspect that the watch may be magnetized, please calibrate the alignment of the directional Sensor Digital and Manual Corrections.
- The reason why the direction measured is incorrect
- If the direction is incorrect, please conduct direction correction. If measure direction near strong magnetic field, such as home electrical appliance, large iron bridge, steel pillar, overhead cable, etc. or measured the direction in a train or ship, it will result in error. Please move away from the large metal object and measure the direction once again. Please note that the digital compass can not be used in train or ship.
- Why different results will be produced when measure direction in a same place?
- The magnetic force from high voltage cable nearby give interference to the geomagnetic detection by this watch. Please move away from high voltage cable and do detection once again.
- Why problem occurs when measure direction indoor?
- TV set, personnel computer, speaker or other objects will interfere in the geomagnetic detection by this watch. Please keep away from interferential objects or do detection outdoor. It will be more difficult when do direction detection within a building made of reinforced concrete. Please note that the direction
- The working principle of altimeter:
- As the height increases, the pressure and temperature usually decrease. Height measurements of this watch is based on International Standard Atmospheric Pressure (ISA) values developed by the International Civil Aviation Organization (ICAO), which define the relationship between altitude, pressure and temperature.
(Relationship between altitude, pressure and temperature)
- Pay attention to the accuracy of any situation as below, measurements will be affected:
- When the Pressure changes as a result of a change in the weather, when the temperature is extremely variable, When this watch is strongly impacted.
- There are four ways of expressing height: 1, Relative height. 2, Height where is located. 3, Altitude. 4, Default height of the factory.
- The following illustration shows the relative height and altitude. Absolute height refers to the
- altitude. the relative height is the difference between two different positions.
- Precautions on the simultaneous measurement of height and temperature:
- Although height and temperature can be measured simultaneously, note that the best results are determined under different conditions. When measuring the temperature, it is best to remove the watch from the wrist to reduce the effect of body temperature on the measurement, but when measuring the height, it is best to wear the watch on the wrist , because it can keep the temperature of the watch stable and improve the precision of height measurement.
- Below is the measure of height or temperature you need to take steps first :
- When height determination is prioritized, the user who wear the watch on the wrist or place it in other places where the temperature of the watch is stable.
- The watch should be removed from the wrist and suspended from the bag or where it is not directly exposed to the sun when temperature measurement is prioritized. Pay attention to remove the watch from the wrist when measuring pressure value of the sensor will be affected by the short. The air pressure sensor in this watch can be used to determine the change of air pressure for your personal forecasting weather. The sensor is not a precision device that can be used for formal weather prediction or reporting.
- Sudden changes in temperature can affect the measurement results of the sensor.
- The temperature will be measured by the body temperature (when you wear a watch), direct sunlight and humidity, in order to make the measurement of the temperature more accurate, please remove the watch from the wrist and place it in a place free of direct sunlight and Well-ventilation Place and dry the case, which takes about 20 to 30 minutes to reach the actual ambient temperature.
- The Working principle of barometer:
- Atmospheric pressure responses to changes in the weather, which can be predicted within reasonable accuracy by observing changes in the weather, as a rise in atmospheric pressure indicates a good weather, while a drop in atmospheric pressure indicates a worsening of the weather.
- The atmospheric pressure published in the newspaper and reported in the television weather forecast is modified to be a measured value at sea level (0 m above sea level).
- Important tips: quality standard
- The first time you use the compass function after each battery change, you must rotate the watch (left or right) two times, and use it to automatically correct the compass of digital gongs, and the air pressure, height, temperature will automatically use factory defaults, if there is no high precision barometer, thermometer, compass gong and other instruments as a calibration reference, please do not arbitrarily carry out the relevant digital correction!
- Air pressure or height has been adjusted due to operation error during use, please confirm the default value of the factory according to the instructions.
- Sensor power status:
- The weather forecast is automatically detected every hour for 2s.
- Use a digital compass for 1 minute, the sensor works for the first 30 seconds, but will be turned off after 30 seconds.
- Use a barometric test for 1 minute and check every 5 seconds for 2s.
- Use the height test to start measuring every 5 seconds within 3 minutes for 2s and test every 2 minutes after 3 minutes for 2s.
