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.
