WeatherHawk SM-18 Skymate Wind Meter w/Temp & Wind Chill - Manual (Page 3)

TAKING MEASUREMENTS: Hold or place the meter so
airflow enters the vane (impeller) from the rear of the unit.
When holding the meter, hold it at arm’s length, away from
your body. CAUTION: The Skymate is very accurate at low
and mid-range air speeds. Consistent use at very high
speeds, ie. from the window of a fast-moving car, will
damage the impeller’s bearing and reduce accuracy. See
below for impeller replacement.
WINDSPEED AVERAGE MODE: You may select average
readings over 5 (AV5), 10 (AV10) or 13 (AV13) seconds.
Press MODE repeatedly to select desired average.
Example: Select AV5 then press ON/OFF key to start the
display. Reading will appear and freeze after 5 secs. Press
ON/OFF to restart. Same applies to AV10, AV13. To exit,
press the MODE button until the icons at the top disappear.
MAXIMUM WINDSPEED HOLD: Press the MODE button
repeatedly until the MAX icon appears. After a measurement
session, the LCD will show the highest windspeed measured
since selecting the MAX icon. Press the MODE button
repeatedly to return to current windspeed or other options.
DISABLE AUTO-OFF FEATURE: Turn OFF the unit by
holding the ON/OFF button for approx. 3 seconds. Then hold
down the ON/OFF button until the display shows “n,” then
release the ON/OFF button. The AUTO-OFF feature is now
invalid. To reactivate, repeat the process until the “n”
disappears.
LOW BATTERY: When you see the battery icon in the upper
R corner, the battery is low and should be changed as soon
as possible, or accuracy will become an issue. Skymate uses
a Lithium CR2032 battery, available almost anywhere. To
