Page 6: Hold Function
Cycling Through Measurement Parameters Press the Set button briefly to change the displayed parameter. The instrument will cycle through the parameters in the following order: Wind Speed » Wind Chill » Temperature » Relative Humidity » Heat Index » Dew Point » Barometric Pressure » Pressure Altitude. Hold Function To freeze the current reading, press the Units button for more than 2 seconds. - Page 7 Min: When in this mode the meter will display the minimum value registered. AVG: When in this mode the meter will display the average of all values since it was powered on. NOTE: The Max, Min and Avg values will be reset when the meter is turned off.
- Page 8 Parameter 1: Wind Speed To measure wind speed, hold the anemometer into the wind or air flow you want to measure, and the device instantly begins displaying wind speed in miles per hour (mph). To change the unit, press the Units button.
- Page 9 Parameter 2: Wind Chill Wind chill is the perceived lowering of air temperature experienced on exposed skin due to wind. The faster the wind blows, the more readily it cools your skin as it replaces the ambient warm air surrounding your skin. In other words, the air “feels” colder than it is because of the chilling effect of the wind.
- Page 10 Parameter 3: Temperature After turning the unit on, press the Set button twice to display temperature. To take a measurement, hold the anemometer so air passes through it. Temperature response depends upon air flow through the unit due to the location of the temperature sensor inside the unit.
- Page 11 Parameter 4: Relative Humidity Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air can "hold" at that temperature. To measure relative humidity, turn on the anemometer, and press the Set button 3 times. The display will show “%RH” below the value of relative humidity.
- Page 12 Parameter 5: Heat Index The heat index is what the temperature feels like to the human body when relative humidity is combined with air temperature. Heat index is only valid at temperatures at or above 80 °F. The human body cools itself by perspiration, which removes heat from the body by evaporation.
- Page 13 Parameter 6: Dew Point Temperature The dew point is the temperature at which air is saturated with water vapor. When air has reached the dew-point temperature the water vapor is condensing at the same rate at which liquid water is evaporating.
- Page 14 Parameter 7: Barometric Pressure Barometric pressure is the force per unit area exerted by the entire column of air above that area. Barometric pressure measurements are displayed by the anemometer in inches of mercury (inHg), hectopascal (hPa), or millibar (mbar). Standard sea-level pressure, by definition, equals 29.92 inches of mercury.
- Page 15 Parameter 8: Pressure Altitude & Relative Altitude The eA980R measures pressure altitude and not absolute altitude (unlike a GPS). Pressure altitude is a relative altitude measurement based on barometric pressure. Pressure altitude is the altitude indicated by an altimeter that is adjusted to measure height above the Standard Datum Plane.
- Page 16 Relative Altitude Measurement: The ennoLogic anemometer is able to display relative altitude (also referred to as climb or ascent/descent). Relative altitude allows you to measure changes in altitude from the point where you enter “Relative Altitude” mode. To enter this mode, press the Set button until you get to altitude, then press and hold the Units button for five seconds.
- Page 17 Number Calibration Function Mode Wind Speed Temperature Relative Humidity Barometric Pressure Pressure Altitude Step 3: Press the Units button to choose the digit you wish to change (the selected digit will flash). Use the Set button to change the value. Step 4: Press the Power button for more than 2 seconds to store the new value and to exit calibration mode.
- Page 18 determine the offset, you calibrate the anemometer to an altitude of "00000". Then turn it back on (into normal operating mode) and read the altitude. This is your offset. Subtract the offset from your true local altitude, and calibrate the anemometer to the resulting value. Example: Your anemometer displays a pressure reading of 29.95 inHg.
- Page 19 Battery Replacement: The ennoLogic anemometer uses one LIR2032 3.6V Lithium-Ion coin cell battery. This battery can be recharged using a LIR2032- compatible coin cell charger. If you choose to replace it with a new LIR2032 battery instead, make sure to recycle the old battery.
