INTRODUCTION Thank you for purchasing General Tools & Instruments’ DAF4207SD AnemometerThermometer with Datalogging SD Card. Please read this user’s manual carefully and thoroughly before using the instrument. The DAF4207SD is a general-purpose handheld instrument that can make two kinds of measurements: • Air (wind) speed and temperature (simultaneously) • Surface temperature, as measured by an optional Type K or Type J thermocouple The meter comes with a combination air speed-temperature probe.
KEY FEATURES • Includes combination air speed-temperature probe • Displays air (wind) speed in meters/second, feet per minute, kilometers/hr, knots (nautical miles per hour), or miles per hour • Displays temperature in ºF or ºC • Big (2.5 in.

SETUP 1. Choose the power source. Before using the DAF4207SD, make sure it is powered by fresh batteries or an optional 9VDC AC adapter plugged into the bottom jack on its right side (callout 1-12). To remove the battery compartment cover (callout 1-13), remove the two screws holding it in place (callout 1-14). Then install six “AA” batteries in the correct orientation, using the polarity marks on the inside of the compartment as a guide. Replace the cover by replacing the two screws. 2. Install an SD card.
4. Choose a decimal point or comma to represent the decimal division between integers and fractions (for example, American-style 20.88 vs. European-style 20,88). Once you have set the date and time, the display will show the word “bASIC” above the phrase “dEC”. Press the SET ▼ button to make “bASIC” (American style) or “Euro” appear in the upper display, as desired. Press the REC/ENTER button to store the selection as the default. 5. Enable or disable auto power off.
If you choose “yES”, after you press the REC/ENTER button the instrument will prompt you to confirm that decision by displaying the term “Ent” below “yES” and sounding three beeps. To confirm that you want to begin the erasure/formatting procedure, press the REC/ENTER button. “Ent” will then flash several times and the instrument will sound another three beeps to confirm that the SD card has been erased and formatted.
4. To measure surface temperature using a thermocouple, make sure the multifunction probe is not in its socket. Plug an optional Type K or Type J thermocouple into its dedicated socket (callout 1-8 of Fig. 1). Then press the FUNC./HOLD/NEXT button until the display shows the term “tP”. Touch the wire end of the thermocouple to the surface whose temperature you wish to measure. The display will show its temperature (as “ºF” or “ºC”). By default, the DAF4207SD is configured for a Type K thermocouple.
AUTOMATIC VS. MANUAL DATALOGGING The DAF4207SD can automatically log data at a user-selected sampling period from 1 second 3,600 seconds (one hour). To view the sampling time that the instrument has been set up to use, press the LOGGER ▲ button (which has the words “Sampling check” stenciled below it) once. To change the sampling time, perform Step 9 of the setup procedure. 8. To start automatic datalogging, press the REC/ENTER button once. The top line of the display will then show the term “REC”.
TRANSFERRING DATA FROM THE SD CARD TO A COMPUTER After automatic or manual datalogging of measurements, remove the SD card from the instrument and plug it into your computer either directly (if it has an SD card slot) or through an SD card reader. Because the files containing time-stamped data logs have the file extension .xls, they open in Microsoft’s Excel application. Figures 2 and 3 show two kinds of Excel presentations: a data-only screen and a graphics-only screen. Fig. 2.
SPECIFICATIONS Embedded microcontroller Custom one-chip LSI device Display type Liquid-crystal with green backlight Display size 2.05 x 1.5 in. (52 x 38mm) Parameters measured Air speed, temperature Measurement range For temperature, 32° to 122ºF (0º to 50ºC); for air speed: 0.4 to 30 m/sec, 1.4 to 126 km/hr, 0.9 to 78.3 mph, 0.8 to 68 knots, 79 to 6890 ft/min Measurement accuracy For air speed: ± (2% + 0.2 m/sec), ± (2% + 0.8 km/hr), ± (2% + 0.4 mph), ± (2% + 0.
MAINTENANCE & TROUBLESHOOTING TIPS Keep the combination probe clean. Store it in the carrying case when you are not using the instrument. When the icon appears in the left corner of the display, it’s time to replace the six “AA” batteries that power the instrument (although measurements will remain valid for several hours after the low-battery indicator first appears). Replacing the batteries requires removing the two screws that hold the battery compartment cover in place, as explained earlier.
RETURN FOR REPAIR POLICY Every effort has been made to provide you with a reliable product of superior quality.
