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 ac cess ories have been al r eady described in th e "Appendix A: Enclosure"
of this Manual. You can check wh ether ther e is any loss of accesso ries wi th referenc e
to this description. If it is found that there is any accessory lost or damaged, pleas e 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 i s damag e to the inst rument caus ed by the t ransportat ion, pl ease 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

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 present s 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 connecto r of the prob e 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).

How to Set the Probe Attenuation Coefficient
The probe has sev eral att enuation 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) Press the function menu button of the used channels (CH1 MENU or CH2
MENU).
(2) Press H3 button to display the Probe menu; press the F1 button t o select Attenu.
In the menu at the l eft of the screen, turn the M knob to select the p roper value
corresponding to the probe.
This setting will be valid all the time before it is changed again.
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
oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 4-10).
4.Junior User Guidebook
15
Caution:
connect the probe to the
Figure 4-10 Attenuation Switch
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
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, t hen, press H1 button to call out the Function

menu; turn the M knob to choose Adjust. Press H2 button to choose the option "Self
Cal"; run the program after everything is ready.
Introduction to the Vertical System
As shown in Figure 4-12, there are a few of buttons and knobs in VERTICAL
CONTROLS. The following practices will gradually direct you to be familiar with
the using of the vertical setting.
Figure 4-12 Vertical Control Zone
1. Use the "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 waveform.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
component of the signal through the observation of the difference between the wave
form and the signal ground.
If the channel is under the AC mode, the DC component would be filtered out. This
mode helps you display the AC component of the signal with a higher sensitivity.
Vertical offset back to 0 shortcut key
Turn the VERTICAL POSITION knob to change the vertical display position of
channel and press the position knob to set the vertical display position back to 0 as a
shortcut key, this is especially helpful when the trace position is far out of the screen
and want it to get back to the screen center immediately.
2. Change the Vertical Setting and Observe the Consequent State Information Change.
With the information displayed in the status bar at the bottom of the waveform
window, you can determine any changes in the channel vertical scale factor.
4.Junior User Guidebook

How to Set the Vertical System
The VERTICAL CONTROLS includes three menu buttons such as CH1 MENU,
CH2 MENU and Math, and four knobs such as VERTICAL POSITION,
VOLTS/DIV for each channel.
Setting of CH1 and CH2
Each channel has an independent vertical menu and each item is set respectively
based on the channel.
To turn waveform s on or off (ch ann e l, math)
Pressing the CH1 MENU, CH2 MENU, or Math buttons have the following effect:
• If the waveform is off, the waveform is turned on and its menu is displayed.
• If the waveform is on and its menu is not displayed, its menu will be displayed.
• If the waveform is on and its menu is displayed, the waveform is turned off and its
menu goes away.

2. To adjust the probe attenuation
For correct measurements, the attenuation coefficient settings in the operating
menu of the Channel should always match what is on the probe (see "How to Set
the Probe Attenuation Coefficient" on P14). If the att enuation coefficient of the
probe is 1:1, the menu setting of the input channel should be set to X1.
Take the Channel 1 as an example, the attenuation coefficient of the probe is 10:1,
the operation steps are shown as follows:
