Note:
Operation of Max/Min wind flow measurement is the same as
wind velocity.
Date holding /Storage/Reading and clearing
Data holding:
on Measurement state, 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: on
Measurement 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: on Measurement 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 indicated the data
storage function is activated. Press again the “REC”
key to finish data storage. （ Press “REC” Key stop
recording.）
(3) hold the "CLR "button two seconds, and the screen
shows "CLR", all the records will be cleared
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. Short Press “RESET”
key to return normal operation. In data read, read to
10 if you need testing, once again return to read the
state, the data will be then 10 to read ( This product
can store 600 set of data. When the storage area full,
the "full" appeared, Press the "RESET" button back to
measurement state ）As shown in figure 15:
(2) read the value random
In "READ" state, press the "SAMPLE" button to enter
the data read serial number .Then press "ENTER"

Familiar trouble shooting
The following is a list of actions to be to ken if the unit is not
working properly:

battery door on the bottom rear of the unit. The “+”
“-” symbols on the battery should match the
corresponding “+” “-” symbols on the inside of the
battery compartment.
(2) lf the unit can not read the wind flow value properly,
please check if the vane is block or not connected.
(3) If the unit can not read the wind temperature value
properly, please check if the heat resistor is fall off or
damaged by manual.
(4) If the unit can not read data properly, please check it
is operated under the rule temperature and humidity
situation.
(5) when Measure the wind velocity the temperature
display line don't show the number for temperature
overflow or probe fault; When measuring the wind flow ,
area set overflow will appear this situation too
(6) When measuring wind velocity, the wind Velocity
display line appear "OL", for value overflow, wind flow
measurement situations as well.
