MODE button with the meter operating in air speed mode (with
VEL appearing on the top line of the LCD). This will cause VEL to
begin flashing. Then press the MODE button again. On meters that
have come fresh from the factory, this will cause the three terms
WCI, WET and DEW to appear, flashing, on the left side of the
LCD. Within 15 seconds (before the backlight turns off), press the
SET button as many times as necessary until the temperature you
want appears by itself, flashing, on the left side. Note that the
temperature on the lower readout changes with each press of the
SET button. To save the temperature you want, press the MODE
button while its abbreviated term (WCI, WET or DEW) is flashing.
As with air speed units, the type of temperature you select and
save becomes the display default until you change it.
When operating in Wind Chill Index mode, make sure the vane is
perpendicular to the wind direction.
MEASURING AIRFLOW VOLUME
To enter airflow volume measurement mode, begin by pressing
the MODE button with the meter operating in air speed mode
(with VEL appearing on the top line of the LCD). This will cause
VEL to begin flashing. Then press the SET button. This will cause
the flashing term FLOW to replace the flashing term VEL on the
top line of the LCD. To stop FLOW from flashing, press the
MODE button.
Note that the term AREA now appears at the left of the lower
readout. To calculate airflow volume, the DAF3009 must "know"
the area of the grille or duct through which air is passing. Before
entering that area, you should enter your preference for using the
metric or Imperial unit for airflow volume—cubic meters/minute
(CMM) or cubic feet/minute (CFM), respectively.
To change CMM to CFM, begin by pressing the UNIT button. This
will cause CMM to begin flashing. Then press the SET button,

followed by the UNIT button to save the selection.
