6-1 Preparation before execute datalogger function
a. Insert the SD card
* It recommend use memory card 4 GB.≦
Prepare a " SD memory card " ( 1 GB to 16 GB, optional ),
insert the SD card into the " SD card socket " ( 3-19, Fig. 1 ).
The front panel of the SD card should face against 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 8-1, page 21.
*
It recommend strongly, do not use memory cards that
have been formatted by other meter or by a computer.
Reformat the memory card with your meter.
c. Time setting
If the meter is used at first time, it should to adjust the
clock time exactly, please refer chapter 8-2, page 21.
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
8-6, page 24.
