4. MEASURING PROCEDURE

4-1  ANEMOMETER 

1) Install the " Vane Probe Plug " ( 3-9, Fig. 1 ) into the 

" Anemometer Socket " ( 3-13, Fig. 2 ).

2) Power on the meter by pressing the " Power Button " 

( 3-2 , Fig. 1 ) once.

3) Hold the " Vane Probe Handle " ( 3-9, fig. 1 ) by
    hand and let the  " Vane Probe Head " ( 3-8, Fig. 1 )
    face against the measuring air flow source, then the

" Display " ( 3-1, Fig. 1 ) will show air velocity and
the air temperature value together.

Measuring Consideration :
The yellow dot mark on the " Sensor 
head " indicates the direction that need to 
face against the air flow.

The anemometer air velocity unit is default to " m/s ".
If intend change to the other air velocity unit such as
km/h, mph, FPM or knot with default, the detail
procedures please refer

5-1 Change the measuring unit, page 14.

The anemometer air temperature unit is default to "   ".

If intend change temperature unit to "   ", the detail 

procedures please refer

5-3 Change the Temp  ,   unit, page 14.
