Operation

NOTE: For all air velocity or flow measurements, the air should pass through the vane from back to

front. The rear of the vane can be found by locating the mounting nut. The front of the vane has the

engraving "ANEMOMETER". For the best results, maintain a 20

axis of air direction with the rear of

the vane (refer to Fig.2).

Air Velocity

1. Power the meter by pressing .

2. Select Air Velocity measurement

function by pressing . VEL will

appear on the LCD.

3. Press to select the desired unit

of measure (ft/min, mph, km/h, m/s or

knots)

4. Place the vane in the air flow with the

air direction matching the direction of

the arrows printed on the inner walls of the vane. If the unit does not have the printed

arrows, have the tripod mount side of the vane facing the air flow (see Fig.2).

5. Air velocity will be displayed on the bottom line of the LCD.

Temperature

1. When the meter is measuring Air Velocity, Temperature is simultaneously being measured

by the vane's built-in type-K thermocouple.

2. Press to select °C or °F. Temperature is displayed on the upper line of the LCD.

Air Flow

1. Power the meter by pressing .

2. Press to select airflow. FLOW will display.

3. Press to select the desired unit of measure. (CFM, CMM).

4. To enter the area value, press . The lower display line will blank waiting for the user to

program new data. Use the numeric keys to enter a new area value in square feet.

(REMINDER: if measurement is taken in inches, divide by 144 to obtain square feet).

5. Press when finished.

Airflow is based on the specific dimensions of the duct being measured. For the meter to

correctly measure CFM the user must input the area of the duct. Failing to input the correct

area dimensions will result in erroneous readings.

NOTE: If the AVE or the 2/3MAX display icons are displayed in the upper left hand corner of

the LCD, press until they extinguish.

5. Place the vane in the air flow (Fig.2).

6. Wait approximately 2 seconds for a stabilized Air Flow reading.

7. The equation below is used to calculate Air Flow:

AIR FLOW = (AIR VELOCITY) x (AREA)
