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 PeakTech responsible for this service or the PeakTech
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 PeakTech distributor responsible for this business or the PeakTech
local offices. If there is damage to the instrument caused by the transportation, please
keep the package. With the transportation department or the PeakTech
distributor responsible for this business informed about it, a repairing or
replacement of the instrument will be arranged by the PeakTech.
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
bottom left of the instrument.
The instrument carries out all self-check items and shows the Boot Logo. Push the

select Default in the bottom menu. The default attenuation coefficient set value of the
probe on 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 3.3V peak-peak value will be displayed in
several seconds (see Figure 3-5).
Figure 3-5 Auto set
Check CH2, CH3 and CH4 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 on 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

3. Repeat the steps mentioned if needed.
Figure 3-7 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 on the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 - CH4 button).
(2) Select Probe in the bottom menu; select Attenu in the right menu, turn the M
knob to select the proper 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
oscilloscope.
The set values of the probe switch are 1X and 10X (see Figure 3-8).
3.Quick User Guidebook

Caution:
the attenuation switch is set to 1X, the probe will limit the bandwidth
connect the probe to the
Figure 3-8 Attenuation Switch
When
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 3-9.
Figure 3-9 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

Introduction to the Vertical System
As shown in Figure 3-10, there are a few of buttons and knobs in Vertical Controls.
The 4 channels are marked by different colors which are also used to mark both the
corresponding waveforms on the screen and the channel input connectors. Press one
of the channel buttons to open the corresponding channel menu, and press again to
turn off the channel.
Press the Math button to display the math menu in the bottom. The pink M waveform
appears on the screen. Press again to turn off the math waveform.
The 4 channels use the same Vertical Position and Vertical Scale knobs. If you want
to set the vertical scale and vertical position of a channel, please press CH1, CH2,
CH3 or CH4 at first to select the desired channel. Then turn the Vertical Position and
Vertical Scale knobs to set the values.
Figure 3-10 Vertical Control Zone
The following practices will gradually direct you to be familiar with the using of the
vertical setting.
1. Press CH1, CH2, CH3 or CH4 to select the desired channel.
2. Use the Vertical Position knob to show the selected channel waveform in the center
of the waveform window. The Vertical Position knob functions the regulating of the

vertical display position of the selected channel waveform. Thus, when the Vertical
Position knob is rotated, the pointer of the earth datum point of the selected channel
is directed to move up and down following the waveform, and the position message at
the center of the screen would change accordingly.
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 the selected
channel, and push 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.
3. 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.
Turn the Vertical Scale knob and change the "Vertical Scale Factor (Voltage
Division)" of the selected channel, it can be found that the scale factor of the selected
channel in the status bar has been changed accordingly.
Introduction to the Horizontal System
Shown as Figure 3-11, there are a button and two knobs in the Horizontal Controls.
The following practices will gradually direct you to be familiar with the setting of
horizontal time base.

1. Turn the Horizontal Scale knob to change the horizontal time base setting and
observe the consequent status information change. Turn the Horizontal Scale
knob to change the horizontal time base, and it can be found that the Horizontal
Time Base displayed in the status bar changes accordingly.
2. Use the Horizontal Position knob to adjust the horizontal position of the signal
in the waveform window. The Horizontal Position knob is used to control the
triggering displacement of the signal or for other special applications. If it is
applied to triggering the displacement, it can be observed that the waveform
moves horizontally with the knob when you rotate the Horizontal Position knob.
Triggering displacement back to 0 shortcut key
Turn the Horizontal Position knob to change the horizontal position of channel
and push the Horizontal Position knob to set the triggering displacement back to 0
as a shortcut key.
3. Push the Horizontal HOR button to switch between the normal mode and the
wave zoom mode.
Introduction to the Trigger System
As shown in Figure 3-12, there are one knob and three buttons make up Trigger
Controls. The following practices will direct you to be familiar with the setting of the
trigger system gradually.
Figure 3-12 Trigger Control Zone
1. Push the Trigger Menu button and call out the trigger menu. With the operations
of the menu selection buttons, the trigger setting can be changed.
2. Use the Trigger Level knob to change the trigger level setting.
By turning the Trigger Level knob, the trigger indicator in the screen will move
up and down. With the movement of the trigger indicator, it can be observed that
the trigger level value displayed in the screen changes accordingly.
Note: Turning the Trigger Level knob can change trigger level value and it is
also the hotkey to set trigger level as the vertical mid point values of the
amplitude of the trigger signal.
3. Push the Force button to force a trigger signal, which is mainly applied to the
