1.General Safety Requirements
1. General Safety Requirements
Before any operations, please read the following safety precautions to avoid any
possible bodily injury and prevent this product or any other products connected
from damage. In order to avoid any contingent danger, this product is only used
within the range specified.
Only the qualified technicians can implement the maintenance.
To avoid Fire or Personal Injury:
Connect the probe correctly. The grounding end of the probe corresponds to the
grounding phase. Please don't connect the grounding end to the positive phase.
Use Proper Power Cord. Use only the power cord supplied with the product and
certified to use in your country.
Connect or Disconnect Correctly. When the probe or test lead is connected to a
voltage source, please do not connect and disconnect the probe or test lead at random.

markers of this product. Refer to the user's manual for more information about ratings
before connecting to the instrument.
Do not operate without covers. Do not operate the instrument with covers or panels
removed.
Use Proper Fuse. Use only the specified type and rating fuse for this instrument.
Avoid exposed circuit. Do not touch exposed junctions and components when the
instrument is powered.
Do not operate if in any doubt. If you suspect damage occurs to the instrument, have
it inspected by qualified service personnel before further operations.
Use your Oscilloscope in a well-ventilated area. Make sure the instrument installed
with proper ventilation, refer to the user manual for more details.

Introduction to the Structure of the Oscilloscope
When you get a new-type oscilloscope, you should get acquainted with its front panel at
first and the SDS series digital storage oscilloscope is no exception. This chapter makes a
simple description of the operation and function of the front panel of the SDS series
oscilloscope, enabling you to be familiar with the use of the SDS series oscilloscope in the
shortest time.
Front Panel
The SDS series 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 (F1 ~
F5) in the column on the right side of the display screen or in the row under the display
screen (H1 ~ H5) are menu selection buttons, 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 SDS 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.
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 power cord to a power source. Turn on the Power Switch
Button ―○on the left side (make sure the "―"side is pressed down). Then,
push down the button of the " " signal on the top.
The instrument carries out all self-check items and shows the Boot Logo. Press the
"Utility" button, then, press H1 button to get access to the "Function" menu. Turn the
Mknob to select Adjust and press H3 button to select "Default". 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.

4.Junior User Guidebook
Connect the probe tip and the ground clamp to the connector of the probe
compensator.
3. Press the "Autoset"Button.
The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in
several seconds (see Figure 4-7).
Figure 4-7 Auto set
Check CH2 by repeating Step 2 and Step 3.
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 (see "How to Set the Probe Attenuation Coefficient"
on P14), and connect the 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
"Autoset".
2. Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Figure 4-8 and Figure 4-9).

4.Junior User Guidebook
Figure 4-10 Attenuation Switch
Caution:
When the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. To use the full 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 any electric
shock, shown as Figure 4-11.
Figure 4-11 Finger Guard
Warning:
To avoid electric shock, always keep your finger behind the safety guard
ring of the probe during the operation.
To protect you from suffering from the electric shock, do not touch any
metal part of the probe tip when it is connected to the power supply.
Before making any measurements, always connect the probe to the
instrument and connect the ground terminal to the earth.
How to Implement Self-calibration
The self-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. This program must be executed whenever the
change of ambient temperature is 5℃or over.
Before performing a self-calibration, disconnect all probes or wires from the input
connector. Press the "Utility" button, then, press H1 button to call out the Function
