¾ Interface Software Operation：

If program correctly installed and multimeter properly connected，

run PC interface program，press "START" － "PROGRAMS" - "ＤＭＭ" - "DMM"
- “DMM V1.02”，Programs starts, shown in picture 6;
After connecting multimeter to the computer，first power on multimeter,
press the USB button, the communication port will switch on. Data is now
ready for transmission from multimeter port to PC port. Ensure multimeter
is in the data transmission stats, PC start receiving and recording data.

(Picture 7)

The program records all the data in the measuring process and creates
graphs using these data, as shown in picture 7. Within the Graphing Area,
functions include: SAVE, CLEAR, GRAPH PAGE SELECTION, and FULL SCREEN.
Can also set the range for the data of the graph, size of the graph, and
the displaying method. Please see detail below:

Clear Graph：Clear all existing graphs in the program.

Save Graph：Save the displaying graph in “BMP” format,

in desired folder directory; may be used for other
program. (e.g. Printing)
Record per Page：Number of data record within the graph
per page. The default record is 100, record number may
be changed. Default record of 100 means 100 data
readings are used in the display graph.

First Page： Jump to first saved graphing page.
Previous Page: Jump to previous saved graphing page
(For example, jump to graph page 999 from page 1000).

Last Page： Jump to the last saved graphing page.

Next Page： Jump to the next graphing page (For example,
jump to graph page 1001 from page 1000).
Zoom Graph： Enlarge the graph to see the graph more
clearly.See picture 9:

The program can save and clear data from multimeter; can also save
or ignore the duplicate data and choose sampling interval. See picture

Clear Data：Delete current data records.

Save Data ：Save current data records, can save as EXCEL

（*.xls）, or（*.txt）. File can be re-opened in the program later.

Open Data File：Open previously saved file in (*.xls) format.

Print Data: Print existing records

7 / 11
 Duplicate Data：Save same records when current data duplicate the
previous, if not, measurement will stay longer each time. No matter
what choice it is, every data including same records will be taken
into graphing area.
Sampling Interval: Automatically setup for interval time between
each two samplings, taking Second as the Unit if longer sampling
is performed. When the interval time is 10, data recording will
be allowed to start again after at least 10 seconds
Insert data from MULTIMETER: Very useful and able to output data
from MULTIMETER at any time

¾ Alarm setup Instruction：

Alarm function can be setup based on provided data. "SetMax" in picture
11 represents Max limit alarm and "SetMin" for Min limit alarm. Setup
should be done by users. Once finished, alarm range will be shown by red
dial hands. Shift and range value both need to be shown in integral number.
Compared with current integral value and if data outreaches setup range,
OL icon will be flashed on the dial hands as in Picture 12, or beep through
loudspeaker of the computer until measurement data is down with setup
range.

¾ Record Setup：
All measured data are recorded, and it is up to users for Save or Clear.
However recording is not infinite and will slow down computer operation
when exceeding certain amount. Record number is closely connected with
computer configuration, so please select the number under “Record” menu
based on your computer and reference data above.

 Record number selection

Record Number Selection: Recording stops when total record

amount in record area has reached the setting number. For example:
the default number is 10000, recording doesn’t keep going when the
number of record area totals 10000. The software is still running,
however does not release any record data and only does it when users
change the default.
