5. DATALOGGER
5-1 Preparation before execute datalogger function
a. Insert the SD card
Prepare a " SD memory card "( 1 GB to 16 GB, 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 down case.
* It recommend use memory card capacity is
≦
4 GB.
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, page21.
* If the SD card exist the trouble during format by the meter,
use the computer to reformat again can fix the problem.
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 18.
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 20.
5-2 Auto Datalogger ( Set sampling time
≧
1 second )
a. Start the datalogger
Press the " LOG Button ( 3-8, Fig. 1 ) > 1.5 seconds
continuously, the LCD will show the text of " DATALOGGER "
indicator and flashing per sampling time, at the same
time the measuring data along with the time information will
be saved into the memory circuit.

Plug in the SD card into the Computer's SD card slot
( if your computer build in this installation ) or
insert the SD card into the " SD card adapter ". then
connect the " SD card adapter " into the computer.
3)
Power ON the computer and run the " EXCEL software ".
Download the saving data file ( for example the file
name : PMA01001.XLS, PMA01002.XLS ) from the SD
card to the computer. The saving data will present into
the EXCEL software screen ( for example as following
EXCEL data screens ) , then user can use those EXCEL
data to make the further Data or Graphic analysis
usefully.
