If SD card just the first time use into the meter, it
recommend to make the " SD card Format " at first,
please refer chapter 7-1 ( page 11 ).
c. Time setting
If the meter is used at first time, it should to adjust the
clock time exactly, please refer chapter 7-2 ( page 11 ).

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 13.

the SD card will generate a folder :
HTC01
2)If the first time to execute the Datalogger, under the
route HTC01\, will generate a new file name
HTC01001.XLS.
After exist the Datalogger, then execute again, the data
will save to the HTC01001.XLS until Data column reach
to 30,000 columns, then will generate a new file, for
example HTC01002.XLS
3)Under the folder HTC01\, if the total files more
than 99 files, will generate anew route, such as
HTC02\ ........
4)The file's route structure :
HTC01\
HTC01001.XLS
HTC01002.XLS
.....................
HTC01099.XLS
HTC02\
HTC02001.XLS
HTC02002.XLS
.....................
