I.

Software Install

Firstly, you have to obtain the software installation package from

OWON website (www.owon.com.hk) , double-click it, and click according to the
prompts until the installation is completed..
Secondly,use the supplied USB cable to connect the oscilloscope with a PC
through their USB ports.
Note:
 Please select to HID in oscilloscope menu (Press the Utility → F4 → USB,
select HID).
 If you use a USB cable that is not supplied by us, some problems such as
connection error and signal disturbing might occur.

II. User Interface

When the software enters into the main interface as Fig 2-1 which

has eight parts:

Fig 2-1
1. Menu Bar: provide various functions introductions.

2. Tool Bar: provide usual shortcut bar of menu options.

3. Waveform displayed range: the main range waveforms

displayed.

4. Cursor range: provide the following four cursor types to observe

and measure waveforms: none, horizontal line, vertical line,

double line(the horizontal line and the vertical line shows

simultaneously).

5. Channel box range: in which provides information and set

waveforms displayed and hidden, also set one channel as

current waveform.

6. Time base division range: which is used for observe and set the

time base of the current waveform.

7. Voltage division range: which is used for observe and set the

voltage division of the current waveform.

8. Parameter displayed range: which shows the period, frequency

and pk-pk of the current waveform. If the new waveform is

non-periodicity, the period and the frequency are all 0.

Fig 3-4-1

1) Ports-Settings ： Set as USB and search USB port from

connecting oscilloscopes then refresh connecting USB ports.

Custom USB transfer instructions: send command to get which

type of data from the machine by software.

 Fig 3-4-2

The bottom of port setting window is the auto obtained area in

which interval time and save catalogue of auto obtained could be

set up.

2) Get Data : Acquire waveform data from instrument .

Note: You can get the data from instrument after connecting PC

with USB cable and install driver and then choose the correct

interface setting.

Click "browse" to bring out the "save file" dialogue box and set the

save path and file name.

File type may be Vector or Bitmap corresponding suffix .bin or .bmp

which will be acquired after correct setting in the instrument. On

beginning the file format can be viewed from file types and choose

"close window and load" when finishing, only bin file can load

software and show, bmp open by picture tool.

Fig 3-4-3

3) Continue Data Download: Gain data using interval time in

interface set based on continuous "data acquirement" until

clicking Stop.( the interval time should be 500ms or more to

guarantee transmit and operation.).

Vector data will be uploaded and shown immediately, recorded in

hardware. Bitmap file recorded at the same way except for

uploading.

4) Stop Data Download : Stop auto acquiring.

5) Auto Player: automatically display the waveform data.

 Before using the function of Auto Player, you should make sure

that you used the function of auto acquirement to record data files

in hardware, which use a data record directory path. When you

open the AutoPlayer Dialog, [Add] this directory path as a display

[History], Choose [Play Mode] as [Turn] or [Reverse], set the [Time

Delay(ms)], then you can click the Start Arrow Button to display the

record waveform data, it also provides Stop, Next, Previous to

operate, you can also drag the progress item to location.

6) Remote Control（USB Supported）

Through the operation of the software to remotely control the

instrument, set the required parameters.

(5)Language（Fig 3-5）

V. Relevant operations

Some related operations of the software.

1．Operation for waveforms display range: (Fig 5-1-1)

(1) Waveform moving up and down:

Firstly, the position as Fig （CH1）is the zero voltage position of

current waveform.

1)Fine adjustment: drag "CH1" and make the waveform move

up and down on the screen;

2)Coarse adjustment: drag the ruler slider on the right and

make the waveform move up and down, the moving area is the

maximum movable area on time base division ( which could be

check the current blocks on the right of cursor area, a block 1/8

of height of the screen.).

(2) Waveform move left and right: Move the mouse to the waveform,

it becomes icon, then drag the mouse to make the waveform left

and right as Fig 5-1-1;

 Fig 5-1-1

(3) Change the color of waveform: double click "CH1" to bring out

color dialogue box to change the color.

(4) The time base division of current waveform can be shown and

adjusted in such area (as Fig 5-1-2) which is the time range

about one scale on the vertical line (8 scales in the following),

and adjust the scale in the come box, the waveform zoom to the

corresponding division with the centre scale mark as centre

shaft.(Fig 5-1-3).
Fig 5-1-2
 Fig 5-1-3

(5) In this aspect, voltage division can be use to show and adjust

the current waveform which is one scale on the horizontal line

(12 scales in the following, different series with different format

which are only for reference.) and adjust the scale in the come

box, the waveform zoom to the corresponding division with the

zero voltage position as centre shaft.

 Fig 5-1-4

2．Operation in cursor area（Fig 5-2）

There are four cursor types for selection to measure and locate,

such as: none, horizontal line, vertical line, double line (that is

horizontal line and vertical line display at the same time) (Fig 5-2)
 Fig 5-2

(1) None: without measure cursor;

(2) Horizontal line: Drag the two horizontal lines in the waveform

area up and down to measure every voltage value on the

vertical of current waveform, as the above Fig the Y1,Y2 shows

the actual voltage values of the two vertical lines corresponding

to the zero point of current waveforms and dy=y1-y2 which is

the voltage difference value of the two cursor lines;

(3) Vertical line: Drag the two vertical lines in the waveform area left

and right to measure every time value on the horizontal of

 current waveform, as the above Fig the x1,x2 shows the time

value of the two vertical lines( the leftmost is zero value of time),

dx=x1-x2 which is the time difference value of the two cursor

lines.

(4) Double lines (Fig 5-1-3): The vertical line and the horizontal line

are all in the waveform area and be measured at the same time.

3．Operation in channel box（Fig 5-3）

The user can click some channel in the channel box or some

waveform in such area to set the current waveform ( select CH1 or

sampling point in the waveform), then the selected channel would

be high light marked and the corresponding data will be displayed

in the time base division, voltage division and parameter area

simultaneously.
