1. General Safety Requirements
Before use, please read the following safety precautions to avoid any possible bodily
injury and to prevent this product or any other connected products from damage. In
order to avoid any contingent danger, ensure 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.
 Product Grounded. This instrument is grounded through the power cord grounding
conductor. To avoid electric shock, the grounding conductor must be grounded. The
product must be grounded properly before any connection with its input or output
terminal.
When powered by AC power, it is not allowed to measure AC power source
directly, because the testing ground and power cord ground conductor are
connected together, otherwise, it will cause short circuit.
When powered by battery, the product must ground connection. To avoid electric
shock, there must be a ground wire connect between ground and the ground port
(on the back of product panel).
 Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and
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.
 Do not operate in wet conditions.
 Do not operate in an explosive atmosphere.
 Keep product surfaces clean and dry.

How to Implement the General Inspection
After you get a new 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 A: Enclosure"
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 OWON responsible for this service or the OWON'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 OWON's distributor responsible for this business or the OWON's local
offices. If there is damage to the instrument caused by the transportation, please keep
the package. With the transportation department or the OWON's distributor
responsible for this business informed about it, a repairing or replacement of the
instrument will be arranged by the OWON.

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. Long press the button on the
bottom left of the instrument.
The instrument carries out all self-check items and shows the Boot Logo. Push the
Utility button, select Function in the bottom menu. Select Adjust in the left menu,
select Default in the bottom menu. 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. Push the Autoset Button on the front panel.
The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in
several seconds (see Figure 3-6).
Figure 3-6 Auto set
Check CH2 by repeating Step 2 and Step 3.
11

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 P12), 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 push the Autoset button on the front
panel.
2. Check the displayed waveforms and regulate the probe till a correct compensation is
achieved (see Figure 3-7 and Figure 3-8).
Overcompensated Compensated correctly Under compensated
Figure 3-7 Displayed Waveforms of the Probe Compensation
3. Repeat the steps mentioned if needed.
Figure 3-8 Adjust Probe
How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale
factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 or CH2 button).
(2) Select Probe in the bottom menu; select Attenu in the right menu, turn the M knob to
12

select the proper value corresponding to the probe.
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe on the instrument is preset to
10X.
Make sure that the set value of the attenuation switch in the probe is the
same as the menu selection of the probe attenuation coefficient
in the
oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 3-9).
Figure 3-9 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.
Identify the Probe Attenuation Coefficient Automatically
The oscilloscope can identify the probe attenuation coefficient of the 100:1 (impedance
5K±20%) or 10:1 (impedance 10K±20%) probe with the identifying pin. When you
attach the probe, the oscilloscope set the attenuation automatically on the oscilloscope
vertical menu for the channel to match the probe.
For example, if you attach a 10:1 probe with the identifying pin, the screen will prompt
"The probe attenuation factor is X10", and set the attenuation to 10X automatically on the
oscilloscope vertical menu for the channel.
How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against any electric
shock, shown as Figure 3-10.
