Easy & Simple Operating Information:

1. Power the meter by pressing the ON/OFF/HOLD key momentarily. The Dual
   Display will illuminate. The top (larger) display indicates air speed and the lower
   display indicates temperature.
2. Position the meter so that the measured airflow enters the meter vane from the
   rear of the meter (opposite side from the front panel).
3. Select the desired units for air velocity and temperature by momentarily pressing
   the UNITS/MODE key. Temperature units (°F) and Air Velocity unit (KNT)will appear. Press the UNITS/MODE key repeatedly until the desiredunits appears on screen. When finished, press the ON/OFF/HOLD keymomentarily, 1 appears for a sec then it automatically go back tonormal display with the desired units.
4. To Activate Data Hold and freezes the most recent display, press and hold ON/OFF/HOLD key while taking measurements. Press ON/OFF/HOLD key again to return to normal operation and restart the meter.
5. Max operation: After a measurement session, press and hold the UNITS / MODE
   key until the MAX icon appears on the lower left-hand side of the LCD. Both the Air
   Velocity and Temperature indication will represent the highest readings measured
   since the meter was last powered.
6. Average mode operation: Normally the meter averages readings every 2
   seconds. To select 5, 10 or 13 second averaging, first press and hold the
   UNITS/MODE key until the MAX icon appears. Next, press the key again
   momentarily and the AVG icon will appear. The 13 second average mode is
   selected. Now press the key again and the number 5 will appear. Leave it there if
   an average of 5 seconds is desired. Press the key once more for a 10 second
   average mode. To return to normal operation press the UNITS/MODE key
   repeatedly until all lower left-hand icons disappear.
7. Wind chill indicator: Press and hold the UNITS/MODE key until the MAX icon
   appears. Press the key repeatedly until the WCI icon appears. The temperature
   display will now factor in the wind chill. To return to normal operation, press the
   UNITS/MODE key again and the WCI icon will disappear.
8. The meter automatically shuts down to preserve battery life after approx. 20 mins, if meter keys are not touched.
