4. MEASURING PROCEDURE
4-1 Soil moisture/temp. Measurement
1) Power on the meter by pressing the " Power button "
( 3-2, Fig. 1 ) > 3 seconds continuously.
* After already power on the meter, pressing the
" Power button " > 3 seconds continuously will
turn off the meter.

5. DATALOGGER
5-1 Preparation before execute datalogger function
a. Insert the SD card
Prepare a " SD memory card " ( 1 G to 16 G, optional ),
insert the SD card into the " SD card socket " ( 3-11, Fig. 1).
The front panel of the SD card should face against the
the down case.
b. SD card Format
If SD card just the first time use into the meter, it
recommend to make the " SD card Format " at first. ,
please refer chapter 7-6 ( page 16 ).
c. Time setting
If the meter is used at first time, it should to adjust the
clock time exactly, please refer chapter 7-1 ( page 14 ).
d. Decimal format setting
The numerical data structure of SD card is
default used the " . " as the decimal, for
example "20.6" "1000.53" . But in certain
countries ( Europe ...) is used the " , " as the
decimal point, for example " 20, 6 "
"1000,53". Under such situation, it should
change the Decimal character at first, details
of setting the Decimal point, refer to Chapter
7-5, page 1
