5. MEASURING PROCEDURE
5-1 Wind speed 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 value on the " LCD Display "
( 3-5, Fig. 1 ).
5-2 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,
after several 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 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.
5-4 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.

6. DATA LOGGER
The meter can save max. 100 point data into the
the memory circuit
6-1 Save data
1)Turn on the meter.
2)Press the " REC Button " ( 3-4, Fig. 1 ) momentarily,
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

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.
