Making Measurements

Air Velocity Measurements

Air velocity and temperature measurements can be displayed on this meter in the
following units of measure: ft/m (feet per minute) or m/s (meters per second) for
air velocity and °F or °C for temperature.
1. Connect the sensor to the sensor input jack on top of the meter.
2. Turn on the meter using the ON/OFF button.
3. The 'Vel' indicator should appear on the upper left on the LCD. If not, press and
hold the MODE button until a beep is heard. Repeat this procedure until 'Vel'
appears on the display.
4. Place the sensor in the air current to be measured.
5. View the air velocity and temperature readings on the LCD Display. The upper
display shows the air velocity reading. The lower display shows the
temperature.

Air Flow Measurements

In order to take air flow measurements, the area of the duct under test (in ft
must first be determined (check with the duct manufacturer if necessary). Once the
area is known, enter the value as follows:
1. Turn on the meter with the ON/OFF button.
2. Press and hold the MODE button until a beep is heard. "AREA" appears on the
display and one digit will be blinking indicating that value can be changed.
3. Press the HOLD button to adjust the digit to the value needed.
4. Press the AVERAGE button to select the next digit for editing.
5. When the area is correctly entered, press the MIN MAX button once. A beep will
sound and the digits will stop blinking.
6. Press the HOLD button once to store the area value.
