4. MEASURING PROCEDURE
4-1 Air velocity/Temperature measurement
1 )Install the " Probe Plug " ( 3-13, Fig. 1 ) into the
" Input Socket " ( 3-8, Fig. 1 ).
2) Power ON the meter by pressing the " Power Button "
( 3-2, fig. 1 ).
3) a. Select the desired air velocity unit ( m/s, km/h, mph,
knots, ft/min ) by pusing the " unit Button " ( 3-5, fig. 1 ).
b. Select the desired temperature units by pusing the " 蚓/蚌
Button " ( 3-6, fig. 1 ).
4) Use the hand to hold the " Probe Handle " ( 3-12, Fig. 1 ),
face the " Vane Probe Head " ( 3-11, Fig. 1 ) to the
measured wind. In the same time the air velocity and the
temp. value will show on the LCD display.
Measuring Consideration :
The yellow dot mark on the sensor head indicates the
" yellow dot mark " need to face against the direction of
air flow.
4-2 Data Hold, Date Record
1) Data Hold
a. During the measurement, pushing the " Data Hold
Button " ( 3-3, Fig. 1 ) will hold the measured value &
the LCD will indicate " HOLD " symbol.
b. Push the " Data Hold Button " again to release the
data hold function.
2) Data Record ( Max., Min. reading )
a. The data record function records the maximum and
minimum readings. Press the " REC. Button " ( 3-4,
Fig. 1 ) to start the Data Record function and there
will be a " REC " symbol on the display.
5
b. With the " REC " symbol on the display :
* Press the " REC Button " ( 3-4, Fig. 1 ) once, the
" REC Max " symbol along with the maximum value
will appear on the display.
Note :
If intend to delete the maximum value, just press the
" Hold Button " ( 3-3, Fig. 1 ) for a while, and then
the display will show the " REC " symbol only &
execute the memory function continuously.
* Press the " REC. Button " ( 3-4, Fig. 1 ) again, the
" REC Min " symbol along with the minimum value
will appear on the display.
Note :
If intend to delete the minimum value, just press the
" Hold Button " ( 3-3, Fig. 1 ) for a while, and then
the display will show the " REC " symbol only &
execute the memory function continuously.
c. To exit the memory record function, just press the
" REC " button for 2 seconds at least. The display will
revert to the current reading.
5. AUTO POWER OFF DISABLE
The instrument has " Auto Power Off " function in order to
prolong battery life. The meter will shut off automatically if
none of the buttons are pressed in approx. 10 min.
To disable this function, Select the memory record function
during the measurement by pressing the " REC. Button "
3-4, Fig. 1 ).

6. RS232 PC SERIAL INTERFACE
The instrument has RS232 PC serial interface via a 3.5 mm
terminal ( 3-7, Fig. 1 ).
The data output is a 16 digit stream which can be utilized
for user's specific application.
A RS232 lead with the following connection will be required
to link the instrument with the PC serial port.

7. BATTERY REPLACEMENT
1) When the left corner of LCD display show " ", it
is necessary to replace the battery. However, in-spec.
measurement may still be made for several hours after
low battery indicator appears.
2) Slide the " Battery Cover " ( 3-9, Fig. 1 ) away from the
instrument and remove the battery.
3) Replace with 9V battery ( Alkaline or Heavy duty type )
and reinstate the cover.
4) Make sure the battery cover is secured after changing the
battery.
