Operation
Connecting the Vane
1. The vane plug is inserted in the meter’s sensor jack at the top of the meter. The plug and jack
are keyed so that the plug can only fit in the jack one way.
2. Turn the plug carefully until it lines up with the jack and then firmly push the plug in place. Do not
apply undue force or try to twist the plug side-to-side.
3. If the vane is not connected to the meter or if the sensor is defective, the LCD display will
indicate dashed lines in place of an air velocity reading.
Air Velocity Measurements
1. Turn on the meter using the ON/OFF button.
2. Press UNITS button to select the desired unit of measure.
NOTE: At power up the meter will display the last unit of
measure previously entered.
3. Place the sensor in the air stream. Ensure that the air enters
the vane as indicated by the arrow sticker placed inside the
vane. Refer to the diagram.
4. View the air velocity and temperature readings on the LCD
Display. The large main LCD display shows the Air Velocity
reading. The upper right LCD sub-display shows the
temperature reading.
