Displaying Min/Max/Avg Air And Wind Speeds - General DAF3012M User Manual

effect of wind speed or humidity (Wind Chill Index, or Wet Bulb
and Dew Point temperatures, respectively), begin by pressing the
MODE button with the meter operating in air/wind 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, DEW and WET to appear, flashing, above the
lower readout (Fig. 2, Callout J). 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, above the lower readout. Note that the temperature
below changes with each press of the SET button. To save the
temperature you want, press the MODE button while its
abbreviated term (WCI, DEW or WET) is flashing.
As with air/wind 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.
DISPLAYING MIN/MAX/AVG AIR
AND WIND SPEEDS
The DAF3012M keeps track of the maximum and minimum
(fastest and slowest) and average air speed values recorded over
a measurement "session"—the period of time during which you
measure speeds at multiple locations and/or speeds of multiple
devices. The session begins when you power on the DAF3012M;
it typically ends 5 minutes after you finish making measurements
with the activation of the APO function.
The value of being able to quickly determine, for example, the
fastest and slowest fans of a group should be obvious.
To display the maximum, minimum or average air/wind speed
during a measurement session, press the DISP button as many
times as necessary until the label of the desired value (Max, Min
