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. Air speeds can
be displayed in m/s (meters/second), fpm (feet per minute), km/h (kilometers/hr),
knots (nautical miles per hour), or mph (miles per hour). Temperatures can be
displayed in ºF (Fahrenheit) or ºC (Celsius) units.

Several features and capabilities enhance the instrument’s versatility. Among them
are automatic temperature compensation for measurements made by the
combination probe or Type K or J thermocouples, the ability to hold readings and
display maximum and minimum readings, and an automatic power off function that
extends battery life.

Because it is microprocessor-based, the DAF4207SD can make full use of the
portability, reliability and large storage capacities that SD memory cards offer.
Measurements can be made automatically at any sampling rate between one second
and one hour. After storing and time-stamping the measurements on an SD card
plugged into the instrument (a process called datalogging), the user can remove the
card and plug it into to a laptop or desktop computer either directly or via a USB card
reader. The data logs are stored on the card as files with the .xls extension, which
can be opened by Microsoft’s Excel application.

The DAF4207SD has a backlit 2-1/2 in. diagonal display and is powered by six “AA”
Alkaline batteries or an optional 9-VDC AC adapter.
