Introduction to the Front Panel and the User's Interface of the
MSO series Oscilloscope
When you get a new-type oscilloscope, you should get acquainted with its front panel at
first and the MSO series mixed digital storage oscilloscope is no exception. This chapter
makes a simple description of the operation and function of the front panel of the MSO
series mixed oscilloscope, enabling you to be familiar with the use of the MSO series
mixed oscilloscope in the shortest time. The MSO series mixed oscilloscope offers a
simple front panel with distinct functions to users for their completing some basic
operations, in which the knobs and function pushbuttons are included. The knobs have the
functions similar to other oscilloscopes. The 5 buttons in the column on the right side of
the display screen are menu selection buttons (defined as F1 to F5 from top to bottom
respectively), through which, you can set the different options for the current menu. The
other pushbuttons are function buttons, through which, you can enter different function
menus or obtain a specific function application directly.

How to implement the General Inspection
After you get a new MSO series oscilloscope, it is recommended that you should
make a check on the instrument according to the following steps:
1. Check whether there is any damage caused by transportation.
If it is found that the packaging carton or the foamed plastic protection cushion has
suffered serious damage, do not throw it away first till the complete device and its
accessories succeed in the electrical and mechanical property tests.
2. Check the Accessories
The supplied accessories have been already described in the Appendix B
“Accessories” of this Manual. You can check whether there is any loss of accessories
with reference to this description. If it is found that there is any accessory lost or
damaged, please get in touch with the distributor of LILLIPUT responsible for this
service or the LILLIPUT’s local offices.
3. Check the Complete Instrument
If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in touch
with the LILLIPUT’s distributor responsible for this business or the LILLIPUT’s
local offices. If there is damage to the instrument caused by the transportation, please
keep the package. With the transportation department or the LILLIPUT’s distributor
responsible for this business informed about it, a repairing or replacement of the
instrument will be arranged by the LILLIPUT.

User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
How to implement the Function Inspection
Make a fast function check to verify the normal operation of the instrument, according
to the following steps:
1. Connect the Instrument to the Power and Push down the Power Switch Button.
The instrument carries out all self-check items and shows the prompt “Press any Key
Enter system”. Press the “8 (UTILITY)” button to get access to the “FUNCTION”
menu and push down F2 the menu selection button to call out the function “Recall
Factory”. The default attenuation coefficient set value of the probe in the menu is
10X,
2. Set the Switch in the Oscilloscope Probe as 10X and Connect the Oscilloscope
with CH1 Channel.
Align the slot in the probe with the plug in the CH1 connector BNC, and then tighten
the probe with rotating it to the right side.
Connect the probe tip and the ground clamp to the connector of the probe
compensator,.
3. Press the “7(AUTOSET)” Button.
The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in
several seconds (see Fig. 4).
Fig. 4 Auto set
Check CH2 by repeating Step 2 and Step 3.

User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
How to Implement the Probe Compensation
When connect the probe with any input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the measuring error
or mistake. For adjusting the probe compensation, please carry out the following
steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of the
switch in the probe as 10X, and connect the oscilloscope probe with the CH1
channel. If a probe hook tip is used, ensure that it keeps in close touch with the
probe. Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of the
probe connector, and then press the button “7(AUTOSET)”.
2. Check the displayed wave forms and regulate the probe till a correct
compensation is achieved (see Fig. 5 and Fig. 6).
Fig. 5 Displayed Wave Forms of the Probe Compensation
3. Repeat the steps mentioned if necessary.
Fig. 6 Adjust Probe
18

User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
If it is required to change (check) the set value of the probe attenuation coefficient,
press the function menu button of the channels used, then push down the selection
button corresponding to the probe till the correct set value is shown.
This setting will be valid all the time before it is changed again.
Note: The attenuation coefficient of the probe in the menu is preset to 10X when
the oscilloscope is delivered from the factory.
Make sure that the set value of the attenuation switch in the probe is the same as the
menu selection of the probe in the oscilloscope.
The set values of the probe switch are 1X and 10X (see Fig. 7).
Fig. 7 Attenuation Switch
Note: When the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. If it is needed to use the whole bandwidth of the
oscilloscope, the switch must be set to 10X.
How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against the electric
shock, shown as Fig. 8.
Fig. 8 Finger Guard
Warning: In order to avoid suffering from the electric shock, please keep your
finger behind the safety guard ring of the probe body during the operation.
In order to protect you from suffering from the electric shock during your using the
19

User’s Manual of OWON Color Mixed Signal Digital Storage Oscilloscope
probe, do not touch the metal part of the probe tip when the probe is connected to
the power supply.
Before making any measurements, please connect the probe to the instrument and
connect the ground terminal to the earth.
How to Implement Auto-calibration
The auto-calibration application can make the oscilloscope reach the optimum
condition rapidly to obtain the most accurate measurement value. You can carry out
this application program at any time, but when the range of variation of the ambient
temperature is up to or over 5, this program must be executed.
For the performing of the self-calibration, all probes or wires should be disconnected
with the input connector first. Then, press the “8(UTILITY)” button to call out the
FUNCTION menu; push down the F3 menu selection button to choose the option
“ Do Self Cal”; finally, run the program after confirming that everything is ready now.
Introduction to the Vertical System
Shown as Fig.9, there are a series of buttons and knobs in VERTICAL CONTROLS.
The following practices will gradually direct you to be familiar with the using of the
vertical setting.
Fig. 9 Vertical Control Zone
1. Use the button “VERTICAL POSITION” knob to show the signal in the center
of the waveform window. The “VERTICAL POSITION” knob functions the
regulating of the vertical display position of the signal. Thus, when the
“VERTICAL POSITION” knob is rotated, the pointer of the earth datum point
of the channel is directed to move up and down following the wave form.
