INTRODUCTION

Thank you for purchasing General Tools & Instruments’ DAF3008 Mini Digital
Anemometer with Wind Chill. Please read this user’s manual carefully and
thoroughly before using the product.

The DAF3008 is an inexpensive one-piece vane anemometer that can
accurately measure airflow speeds outdoors, in ducts, and at input and output
grilles of HVAC/R systems. In addition, its ability to measure wind chill makes
this anemometer invaluable to cold-weather sportsmen such as winter
campers, mountaineers and skiers.

KEY FEATURES

• Six available air speed units: ft./min, mph, m/sec, m/min, km/hr, knots

• Also displays temperature and wind chill index in °C or °F

• Calculates Min, Max and Avg air speed values during measurement
sessions up to 5 minutes long

2

• Large backlit LCD • Data hold button

• 5-minute Auto Power Off

• Small and light enough for one-handed operation

• Includes battery and wrist strap

• CE and RoHS approved • 1 year limited warranty

WHAT’S IN THE PACKAGE

The anemometer comes in a blister pack along with a “CR2032” battery and
this user’s manual.

SETUP INSTRUCTIONS

ACTIVATE BATTERY

1. Turn the anemometer over and use a coin to open the battery
compartment at the bottom of the unit.

2. Remove the activation tab under the pre-installed “CR2032” battery.

3. Replace the battery compartment cover and hand-tighten it with the coin.

Complete Setup by carefully removing the plastic film protecting the LCD.

OPERATING INSTRUCTIONS

MEASURING REAL-TIME AIR SPEEDS

To power on the DAF3008, briefly press the /WCI button. The LCD will
illuminate with the backlight on and the unit will automatically enter real-time
measurement mode. The backlight will turn off after 15 seconds if no front­panel button is pushed. Pushing any button begins another 15 seconds of
backlight.

4

To power off the DAF3008, press and hold the /WCI button for at least
3 seconds.

To make a measurement, turn the vane at the top of the unit perpendicular to
the source of air or wind. Allow a few seconds for the reading to stabilize. It
makes no difference whether the front of back of the vane faces the wind or air
flow. The measured air speed value will appear on the upper readout of the LCD
(Fig. 2, Callout M).

The DAF3008’s default air speed unit is ft/min
(fpm). To change the air speed unit, press the

UNIT button once. On the top line of the LCD,
ft/min will begin flashing. Then press the
SET/HOLD button as many times as necessary

until the desired air speed unit appears,
flashing, on the top line. The figure at right
shows the six available air speed units in their
selection sequence.

To save the selected air speed unit, press the
UNIT button twice. The label of the selected unit will stop flashing and the
anemometer will resume operating in real-time measurement mode.

The DAF3008 will “remember” the air speed unit in use when it powers off and
will resume using that unit upon restart. So if you always use fpm, you need not
perform the above procedure. And if you always use the same air speed unit
other than fpm, you need only perform the above procedure once—until the
next battery replacement.

The DAF3008 also measures ambient temperature for display on the LCD’s
lower readout (Fig. 2, Callout N). The DAF3008’s default temperature unit is °F.
To change the temperature unit, press the UNIT button twice. In the bottom
right corner of the LCD, °F will begin flashing. To switch to °C, press the
SET/HOLD button. °C will replace °F, flashing. To save °C as the temperature
unit, press the UNIT button. °C will stop flashing.

To hold any reading (“freeze” the display), press and hold the SET/HOLD
button for at least 3 seconds. To release the hold and resume displaying real­time values, press the button again. This function is very useful for making
measurements in low light or when the source of air or wind is above your
head, below your knees, or around a corner. You can make a measurement,
hold it, and then read the display up to 5 minutes later after re-positioning the
LCD at eye level.

Why do you have only 5 minutes? To extend battery life, the DAF3008
automatically powers itself off following any 5-minute period in which no front­panel button is pressed.

DISPLAYING MAXIMUM, MINIMUM AND AVERAGE SPEEDS

The DAF3008 keeps track of the maximum and minimum (fastest and slowest)
and average air speed values recorded during a measurement “session”—the
time during which you measure speeds at multiple locations and/or speeds of
multiple devices. The session begins when you power on the DAF3008; it
typically ends 5 minutes after you finish making measurements with the
activation of the Auto Power Off (APO) function.

The value of being able to quickly determine the fastest and slowest fans of a
group, or the average of a group of fans, should be obvious.

To display the maximum, minimum or average
air speed during a measurement session, briefly

press (but do not hold) the SET/HOLD button as
many times as necessary until the label of the
desired value (Max, Min or Avg) appears at the
left of the LCD (Fig. 2, Callouts G through I). The
figure at right shows the three available session
parameters in their selection sequence relative to
real-time measurement mode.

CALCULATING WIND CHILL INDEX

The DAF3008 can calculate the Wind Chill Index (WCI) using a complex formula
that takes into account its measurements of air speed and ambient
temperature. To display the Wind Chill Index, briefly press (but do not hold)
the /WCI button. The calculated wind chill value will replace ambient
temperature on the lower readout and the text WCI will appear in the lower left
corner of the LCD.

To resume showing ambient temperature on the lower readout, press the

/WCI button again. WCI will disappear from the LCD.

Note: WCI values are invalid at wind speeds below 3 mph (264 fpm or

1.34 m/s).

MAINTENANCE TIPS

When the icon appears in the lower left corner of the LCD, it’s time to
change the anemometer’s “CR2032” battery (although measurements will
remain valid for several hours after the icon first appears). To change the
battery, follow the Setup Instructions on p. 4.

Remove the battery if you do not expect to use the DAF3008 for an extended
period of time (months or years).

Replace the vane and sensor protection cap (Fig. 1, Callout A) following each
measurement session.

Do not drop or disassemble the unit or immerse it in water.
Do not operate the anemometer:

• Near a magnet

• Near equipment like arc welders and induction heaters that generate an
electromagnetic field

• In environments full of water vapor, dust or static electricity

To clean the housing or LCD, use a dry or damp cloth. Avoid using chemical
cleaners.
