4. PRECAUTIONS & PREPARATIONS FOR
MEASUREMENT
1)
Ensure that the DC 9 V ( 006P, MIN1604 ) batteries are connected
with the right polarity and placed in the battery compartment
correctly.
2) Place the Red & Black Test Leads into the proper input
terminal before making measurement.
3)
Remove either of the test leads from the circuit when
changing the measurement range.
4)
Except operate the " Data Hold " function, it should
cancel the " Data Hold " function, otherwise the display
reading will freeze permanently.
5) Do not exceed the maximum rated voltage and current to
the input terminal.
6) Always switching the " Function Rotary Switch " to the
" Off " position when the instrument is not operation.
7)
Remove the battery if the instrument is not to be used in
a long period of time.
8)

leads, it should use the replace test leads that already
approval of " CATIII-1000 V " at least.
9)
Power On/Off management :
a.
When not use the meter, should rotate the " Function rotary
switch " ( 3-10, Fig. 1 ) to the " OFF " position.
b.
During the measurement, after 10 minutes the meter
will auto power off. If intend to power on again, it
should rotate the " Function switch " to " OFF "
position then set to the new desiring function position.
c.
Disabling auto power off ( not auto power off )

6-5 Micro SD Card Data structure
1) When the first time, the Micro SD card is used into the meter,
the Micro SD card will generate a route :
DMA01
2) If the first time to execute the Datalogger,
under the route DMA01\, will generate a new
file name DMA01001.XLS.
After exist the Datalogger, then execute again,
the data will save to the DMA01001.XLS until
Data column reach to 30,000 columns, then
will generate a new file, for example DMA01002.XLS
20
3) Under the folder DMA01\, if the total files more
than 99 files, will generate anew route, such as
DMA02\ ........
4) The file's route structure :
DMA01\
DMA01001.XLS
DMA01002.XLS
.....................
DMA01099.XLS
DMA02\
DMA02001.XLS
DMA02002.XLS
.....................
DMA02099.XLS
DMAXX\
.....................
.....................
Remark :
XX : Max. value is 10.
7. Saving data from the Micro SD card
to the computer ( EXCEL software )
1) After execute the Data Logger function, take away the
SD card out from the " Micro SD card socket " ( 3-18, Fig. 1 ).
2) Plug in the Micro SD card into the Computer's Micro SD card slot
( if your computer build in this installation ) or
insert the Micro SD card into the " Micro SD card adapter ". then
connect the " Micro 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 : DMA01001.XLS, DMA01002.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.
