When heater activated, heat will be trapped inside to warm up the sonic reflection surface, and alkaline batteries are extremely susceptible to leakage when temperature is over certain limits. So Alkaline batteries are forbidden to be used with this anemometer.

    Make sure the mounting tube for the sensor package is installed vertically (use a level at 90-degree offsets around the tube). Adjust the mounting pipe as necessary. Next also make sure the mounting of the anemometer body on the pipe is level. If it is not, wind direction and speed readings may not operate correctly or accurately.

    Note: If no LED light up or is lighted permanently, make sure the battery is inserted the correct way or a proper reset is happened. Do not install the batteries backwards. You can permanently damage the outdoor sensor. We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for most climates.

    5.5.1 Calibration of anemometer sensor package The ultrasonic sensor has been calibrated before leaving the factory. We do not recommend that customers do calibration by themselves. Customers use this feature only when the wind speed does not return to zero when there is no wind After the product works normally, use a cloth or sponge with good water absorption (prevent the echo of the ultrasonic waves) to completely wrap the...
  • Page 38 There are different manners in which to handle this adjustment. We will outline a reliable procedure below, which requires adjusting both pressures. The method assumes that you have an official airport sufficiently nearby to act as a reliable reference. Usually distances of up to 25 miles work reliably, but this is not always true and depends on geography.
  • Page 39 to compute relative pressure (sea level equivalent). Correction tables can be found on-line in many places. One example is the table found at the web site at https://novalynx.com/manuals/bp-elevation-correction- tables.pdf. Locate your elevation in the first column and read the correction in the third column.
  • Page 40 REL value with the value from the airport. IN our example, the REL display was 1022.9 where we expected 1019.1. This then tells us that our displayed REL pressure is 1022.9 – 1019.1 = 3.8 hPa different from the reference source. Since we assumed the absolute pressure measured was correct, and we presumably calculated the elevation related offset correctly, we must conclude that the absolute pressure was not correct after all.
