5. MEASURING PROCEDURE
5-1 Wind speed and Temp. measurement
1)Turn on the meter by pressing the " Power Button "
( 3-2, Fig. 1 ) momentarily.
* Pressing the " Power Button " ( 3-2, Fig. 1 )
momentarily again will turn off the meter.
2)Uses the hand to hold the meter vertically. The " Cup
Vane " ( 3-1 ) will be rotated, shows the measured the wind speed and temperature value on the " LCD Display " ( 3-5, Fig. 1 ).
5-2 Wind speed unit change
1)Meter defaults unit value is " m/s ".
Meter unit value can be changed to " m/s, km/h, knot, ft/min, mile/h "
2)The method to change the unit :
Press the '" Unit Button " ( 3-3, Fig. 1 ) continuously ( > 2 seconds ), the unit will change from m/s, km/h, knot, ft/min, mile/h " in sequence. Until reach the desired unit, release the finger from the " Unit Button " ( 3-3, Fig. 1 ), new unit will saving into the memory circuit no matter the meter is turned off.
* When the display shows " HOLD " ( refer 5-3 )
or " REC " ( refer 5-4 ), it can not change the unit.
5-3 Temp. unit ( , ) change℃℉
Press the '" / Button " ( 3-4, Fig. 1 ) continuously℃℉ ( > 2 seconds ), the Temp. unit will change from to ( or to ) ℃℉ ℉℃

5-4 Data Hold
* During the measurement, press the " Hold Button "
( 3-3, Fig. 1 ) momentarily to hold the measured value. The LCD will show a " HOLD " symbol.
* Press the" Hold Button " once again to release the
data hold function.
5-5 Data Record ( Max., Min. reading )
1)The data record function records the maximum and
minimum readings. Press the " REC Button " ( 3-4, Fig. 1 ) momentarily to start the Data Record function, shows " REC " on the display.
2)With the " REC " symbol on the display.
a) Press the " REC Button " ( 3-4, Fig. 1 ) momentarily,
the " REC MAX " symbol along with the maximum value will appear on the display.
b)Press the " REC Button " ( 3-4, Fig. 1 ) momentarily
again, the " REC MIN " symbol along with the minimum value will appear on the display.
* When display shows " REC MAX " or " REC MIN ",
press the " Hold Button " ( 3-3, Fig. 1 ) momentarily will delete the max. ( min. ) value, the display will show the " REC. " only and execute the memory function continuously.
c) To exit the memory record function, press the
" REC " button for 2 seconds at least. The display will revert to the current reading, not show " REC "

shows " REC " on the display.
3)Press the " Logger Button " ( 3-2, Fig. 1 ) momentarily
will save one measuring value to memory, display will show :
Example :
28
a. The memory position that
72 save the recent data.
b. The memory left space no.
c. a + b = 100
For example : 28 + 72 = 100
4)To exit the memory data logger ( record ) function,
press the " REC " button for 2 seconds at least. The display will revert to the current reading, not show " REC "

Press the " Hold Button " ( 3-3, Fig. 1 ) momentarily, LCD shows " HOLD ". Following, press the " REC Button " ( 3-4, Fig. 1 ) momentarily, display shows :
Example :
28
The total data point that
ttL are saved into the memory.
2)Uses " Button " ( 3-2, Fig. 1 ) or " Button " ▲▼ ( 3-4, Fig. 1 ) to call the data that already saved into the memory.
Note :
During call the data, the unit display will be flashed.
Example :
1.5
m/s " m/s " unit flashing
25.1
* Press " Hold Button " ( 3-3. Fig. 1 ) will exit the
data call function.
