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 OL in place of a Temperature reading.

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.
4. View the 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.
Air Velocity Averaging Mode
1. To enter 20 P
oint Averaging Mode, press and hold the AVG
button until it beeps twice. The AVG icon will be displayed.
