Use and Care Manual

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.
