eA980R Digital Anemometer
User Manual
1. Overview
Thank you for purchasing the ennoLogic eA980R anemometer,
a high quality instrument which measures 8 parameters:
•Wind Speed (mph, m/s, ft/min, knots, km/h)
•Wind Chill (°C / °F)
•Air Temperature (°C / °F)
•Humidity (%)
•Heat ndex (°C / °F)
•Dew Point ((°C / °F)
•Barometric Pressure (hPa, mbar, inHg)
•Pressure & Relative Altitude (m, ft)
The eA980R anemometer comes with many powerful features
including the following:
•LCD with White Backlight
•Beaufort Scale
•Maximum, Minimum, and Average Reading Display
•Hold Function
•Low Battery ndicator
•Auto Power Off (with override option)
•Calibration Function
•CE Certified & RoHS Compliant
Important: This meter is accurate at low and mid-range air speeds.
Consistent use at very high speeds, e.g. from the window of a fast
moving car will damage the impeller’s bearing and reduce accuracy.

How to Use Your Anemometer
Turning the Anemometer On and Off
Press the Power button briefly to turn the anemometer on.
Press the Power button for more than one second to turn the
anemometer off.
After 5 minutes without any operation the anemometer will power
off automatically.
To disable Auto Power Off hold the Set button down while turning
the unit on. You will see the Power Symbol appear on the LCD.
Warning, if you disable Auto Power Off, the meter will stay on until
the battery runs out unless you turn it off manually by holding down
the Power Button.
acklight
Press the Set button for more than 2 seconds to turn the backlight
on or off.
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 C ill » 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. Press it again for more than 2 seconds to exit this mode.
Changing the Measurement Units
n any measurement parameter mode briefly press the Units button
to change the measurement unit displayed. For example, in wind
speed mode choose between mph, m/s, ft/min, knots, and km/h.
Max/Min/Avg Value Measurement Function
This function allows you to track the maximum, minimum and
average of your readings for any parameter each time you power on
the unit.
n any measurement parameter mode briefly press the Power
button to display the Maximum Reading. A second press will display
the Minimum, a third press will display the Average and a fourth
press will return the meter to the real-time current readings.
Max: n this mode the meter will display the maximum value
registered since it was powered on.
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: T e Max, Min and Avg values will be reset w en t e meter is
turned off.
eaufort Scale
The Beaufort scale categorizes wind speed according to observed
conditions at sea or on land:
0 - Calm (<1mph)
1 - Light air (1-3mph)
2 - Light breeze (4-7mph)
3 - Gentle breeze (8-12mph)
4 - Moderate breeze (13-18mph)
5 - Fresh breeze (19-24mph)
6 - Strong breeze (25-31mph)
7 - Near gale (32-38mph)
8 - Gale (39-46)
9 - Strong gale (47-54mph)
10 - Storm (55-63mph)
11 - Violent storm (64-72mph)
12 - Hurricane (>73mph)
The Beaufort scale is displayed in all parameter modes according to
current wind speed (see display legend).
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. To capture and hold a reading press and old t e Units
button for more t an 2 seconds. This is handy for measuring air flow
in difficult situations.
To track maximum, minimum, and average readings simply press the
Power button briefly to cycle through them. For average readings,
keep in mind that periods of zero wind speed may skew your
average. n this case you may want to restart the unit to reset the
Max/Min/Avg data.

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. n other words, the air “feels” colder than it is
because of the chilling effect of the wind.
Wind Chill is expressed as a temperature which is typically lower
than the air temperature. Wind chill temperature is valid only for
temperatures at or below 50 °F with wind speeds above 3.0 mph.
To measure wind chill, press t e Set button once after turning on the
unit.

5. Wind Chill Value
Parameter 3: Temperature
After turning the unit on, press t e 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. Response may be slow at zero air flow (5 to 10 minutes),
but typically only takes 60-90 seconds in steady air flow.
