please do not extrude the sensor tip, which may cause
the inaccuracy measurement )
1). Wait for 2 seconds with the unit is ready for use.
2). Place the probe in the same direction of the wind to
capture the accurate data ,temperature within 20℃
3). Press the LIGHT key to activate or deactivate the

Measurement Of Average Wind Flow
Press the "VEL/FLOW" key to get into "FLOW" mode;
Once again press the "OPTION" key exit to measure-
ment of average wind flow.
Average Wind flow calculate formula
Flow =1/N∑ (Velocity)*(free Area)
Note
The average vaule only displays by pressing NEXT
key ,if there is wind in the duct Area ,then the LCD
Screen will shows the measured Average Wind flow
Aim the at certain point of duct area properly,
press the "NEXT" key, on the right bottom of the LCD
will show serial number, in the meantime you can take
measurement of the first group wind flow values.
As shown in following figure:
probe
Then select another test point, press the NEXT key to
take measurement of the second group average wind
flow values.
Repeat above steps to measure as many as 12 groups
of average wind flow values. As shown in following
figure:
Select your desired unit by pressing the UNIT key,for
example: select CMM for wind flow unit,
2
M for area unit;
Press the "AREA" key, letter on the LCD will disappe-
ared at this time you can input duct area, such as 1.6,
press "ENTER" key confirm;
Press again the "OPTION" key to select "AVG", here the

In wind flow and velocity measuring process, press the
"MAX/MIN" key to obtain the maximum and minimum
values, press again to exit. For example:
1).When measuring maximum value of wind velocity, a
"MAX" will be shown on the upper LCD screen, as
shown in following figure:
2). When measuring minimum value of wind velocity, a
"MIN" will be shown on the upper LCD screen, as
shown in following figure:
Note:
Operation of Max/Min wind flow measurement is the
same as wind velocity.
Max and min measurement
Data holding:
When taking measurement of wind velocity and flow, press
the "HOLD" key to freeze the Data , press the "HOLD" key
again return to normal operation.
Data storage:
1). Instantaneous (one-shot) data storage: under "VEL" state,
set the sampling rate=0 by pressing "SAMPLE" key and
in put a "0" sampling time and then press "ENTER".
Now, each time "REC" is pressed, the present reading
will be stored.
2). Automatic data storage: under "VEL" state, press the "
SAMPLE" key and input sampling rate, (the sampling
rate from 1~99 seconds using the numeric keys to enter
your desire rate,) then press the "ENTER" key to confirm.
Press the "REC" key to begin storing readings in every
sampling rate. The "REC" icon will appear on the LCD
indicating the data storage function being activated. Press
again the "REC"key to finish data storage.
3). Press "REC" Key to stop recording.
Reading data stored sequentially:
1). Press the "READ" key, you can read the stored data
in memory sequentially, the LCD will first shows serial
number then shows the data.
2). Press "RST" key to return normal operation.
