The DAF3009 is a one-piece vane anemometer-psychrometer that can measure all parameters needed to install, test or fine-tune the performance of an HVAC/R system. KEY FEATURES • Measures: Ambient temperature Dew Point and Wet Bulb temperatures Wind Chill Index (WCI) Relative humidity (RH) Air speed Airflow volume Enthalpy • All temperatures displayable in°F (default) or °C • Five available air speed units: ft.
WHAT’S IN THE PACKAGE The meter comes in a blister pack with a “CR2032” button cell pre-installed in the battery compartment. A hard copy of this user’s manual is inside the blister card. PRODUCT OVERVIEW Fig. 1 below shows all controls, indicators and physical structures of the unit, as well as the location of the battery compartment. Fig. 2 shows all possible indications on the unit’s LCD. Fig. 1. The controls, indicators and physical structures of the DAF3009 A. Vane and sensor A protection cap B.

SETUP INSTRUCTIONS ACTIVATE BATTERY 1. Turn the meter over and use your thumbs or a coin to turn the battery compartment cover on the back (Fig. 1, Callout F) clockwise 30 degrees, in the direction marked OPEN. 2. Pull and discard the tab under the pre-installed battery. 3. Replace the battery compartment cover and turn it counterclockwise 30 degrees until it snaps shut. Complete Setup by carefully removing the plastic film protecting the LCD.
When the icon of the mode you want appears, flashing, on the top line, press the MODE button once to stop it from flashing. Doing this will cause one or more measurement unit icons below to begin flashing. Press the MODE button again to stop those icons from flashing. This causes the meter to enter real-time measurement mode for the chosen parameter (air/wind speed, airflow volume, RH or enthalpy). To hold any pair of measurements (“freeze” the readouts), press the HOLD button.
Press the SET button as many times as necessary until the air speed unit you prefer appears, flashing, on the right side of the upper readout. To save this unit, press the UNIT button. The figure at right shows the five available air speed units in their selection sequence. When you press the UNIT button to save your preferred air speed unit, °F—the DAF3009’s factory default temperature measurement unit—will begin flashing on the right side of the lower readout.
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.
You can now measure the area of your grille and duct and enter it into the DAF3009. The meter can accept any area from 0.1 ft2 to 99.9 ft2. Users of metric units must convert their cm2 measurements to ft2 before entering them. To begin, press the AREA button. This will cause the left (most significant) digit on the lower readout to begin flashing. Press the SET button as many times as necessary until the left digit matches the left digit of your grille or duct area.
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 DAF3009; 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 the fastest and slowest fans of a group, or the average of a group of fans, should be obvious.
MEASURING ENTHALPY Enthalpy is a measure of the amount of energy needed to change the state of a substance from a solid to a liquid or from a liquid to a gas. The most common application for the DAF3009’s enthalpycalculating algorithm is measuring the enthalpy of vaporization of air in an HVAC/R system duct. To enter Enthalpy mode, press the SET button with RH flashing on the top line of the LCD. This will change the flashing term to BTU. To stop BTU from flashing, press the MODE button.
Air Speed Measurement Resolutions: 1 ft./min (0.1 m/s) Temperature Measurement Range: 32° to 122°F (0° to 50°C) Temperature Measurement Accuracy: ±1.8°F (1°C) from 68° to 104°F (20° to 40°C); ±3.6°F (2°C) elsewhere in range Temperature Measurement Resolution: 0.
MAINTENANCE TIPS When the icon appears in the upper 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. 6. Install the new battery so the side with the text and + marking faces up. Remove the battery if you do not expect to use the DAF3009 for an extended period of time (months or years).
