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.

Remark :

How to set the sampling time, refer to Chapter 7-2 ,

page 19 .

How to set the beeper sound is enable, refer to

Chapter 7-4, page 20 .

b. Pause the datalogger

During execute the Datalogger function, if press the

" LOG Button " ( 3-8, Fig. 1 ) once will pause the

Datalogger function ( stop to save the measuring data

into the memory circuit temporally ). In the same time

the " DATALOGGER " symbol will stop flashing.

Remark :

If press the " LOG Button " ( 3-8, Fig. 1 ) once again

will execute the Datalogger again, the " DATALOGGER "

symbol will flashing.

c. Finish the Datalogger

During execute the Datalogger function, press the

" LOG Button ( 3-8, Fig. 1 ) > 1.5 seconds continuously

again will finish the Datalogger function, the " DATALOGGER "

text will be disappeared and finish the Datalogger function.

5-5 SD Card Data structure

1) When the SD card is used into the meter, the SD card

When the first time, the SD card is used into the meter,

the SD card will generate a route :

PMA01

If the first time to execute the Datalogger,

under the route PMA01\, will generate a new

file name PMA01001.XLS.

After exist the Datalogger, then execute again,

the data will save to the PMA01001.XLS until

Data column reach to 30,000 columns, then

will generate a new file, for example PMA01002.XLS

Under the folder PMA01\, if the total files more

than 99 files, will generate anew route, such as

PMA02\ ........

The file's route structure :

PMA01\

PMA01001.XLS

PMA01002.XLS

.....................

PMA01099.XLS

PMA02\

PMA02001.XLS

PMA02002.XLS

.....................

PMA02099.XLS

PMAXX\

.....................

Remark :

XX : Max. value is 10.

6. Saving data from the SD card

to the computer ( EXCEL software )

After execute the Data Logger function, take away the

SD card out from the " SD card socket " ( 3-11, Fig. 1 ).

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.

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.

EXCEL data screen ( for example )

EXCEL graphic screen ( for example, graphic )

7. ADVANCED SETTING

Under do not execute the Datalogger function,

press the " SET Button " ( 3-7, Fig. 1 ) continuously at

least two seconds will enter the " Advanced Setting " mode.
