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'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 PEAKTECH's
distributor responsible for this business or the PEAKTECH's local offices. If there is damage to
the instrument caused by the transportation, please keep the package. With the transportation
department or the PEAKTECH's 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. 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 right menu. Select Adjust in the left menu, select Default in the
right 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.
12
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 1-5).
Figure 1-5 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 P13), 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 1-6 and Figure 1-7).
Overcompensated Compensated correctly Under compensated
Figure 1-6 Displayed Waveforms of the Probe Compensation
3. Repeat the steps mentioned if needed.
13
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.
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.
Figure 1-7 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 in the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 or CH2 button).
(2) Select Probe in the right menu; turn the M knob to select the proper value in the left menu
corresponding to the probe.
This setting will be valid all the time before it is changed again.
The set values of the probe switch are 1X and 10X (see Figure 1-8).

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 Use the Probe Safely
The safety guard ring around the probe body protects your finger against any electric shock,
shown as Figure 1-9.
Figure 1-9 Finger Guard
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.
Push the Utility button, select Function in the right menu, select Adjust. in the left menu,
select Self Cal in the right menu; run the program after everything is ready.
Introduction to the Vertical System
As shown in Figure 1-10, 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.
15
Figure 1-10 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 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.
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.
Turn the Vertical Scale knob and change the "Vertical Scale Factor (Voltage Division)", it
can be found that the scale factor of the channel corresponding to the status bar has been
changed accordingly.
Push buttons of CH1, CH2 and Math, the operation menu, symbols, waveforms and scale
factor status information of the corresponding channel will be displayed in the screen.
Introduction to the Horizontal System
Shown as Figure 1-11, 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
16
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 display 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.
