2.3 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:
► 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.
► Check the Accessories
The supplied accessories have been already described in the
"SPECIFICATIONS" 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
PROMAX responsible for this service or the PROMAX local offices.
► 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 PROMAX distributor responsible for this
business or the PROMAX local offices. If there is damage to the instrument
caused by the transportation, please keep the package. With the
transportation department or the PROMAX distributor responsible for this
business informed about it, a repairing or replacement of the instrument will
be arranged by the PROMAX.

2.4 How to Implement the Function Inspection
Make a fast function check to verify the normal operation of the instrument,
according to the following steps:
► Connect the power cord to a power source. 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 M knob to select Adjust and press H3 button
to select "Default". The default attenuation coefficient set value of the
probe in the menu is 10X.
► 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.
► Press the "Autoset" Button.
The square wave of 1 KHz frequency and 5V peak-peak value will be
displayed in several seconds (see Figure 6).
Figure 6. Auto set.
Check CH2 by repeating Step 2 and Step 3.

June 2016 Page 11
2.5 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:
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”), 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".
Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Figure 7 and Figure 8).
Overcompensated Compensated correctly Under compensated
Figure 7. Displayed Waveforms of the Probe Compensation.
Repeat the steps mentioned if needed.
Figure 8. Adjust Probe.

Page 12 June 2016
2.6 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:
Press the function menu button of the used channels (CH1 MENU or
CH2 MENU).
Press H3 button to display the Probe menu; 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 9).
Figure 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.

June 2016 Page 13
2.7 How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against any
electric shock, shown as Figure 10.
Figure 10. Finger Guard.
CAUTION: 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.
2.8 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 ºC 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 menu; turn the M knob to choose Adjust. Press H2 button to choose
the option "Self Cal"; run the program after everything is ready.

Page 14 June 2016
2.9 Introduction to the Vertical System
As shown in Figure 11, 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 11. Vertical Control Zone.
Use the button "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.

June 2016 Page 15
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 "VOLTS/DIV" 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.
Press buttons of "CH1 MENU", "CH2 MENU" 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 12, 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.
Figure 12. Horizontal Control Zone.
Use the horizontal "SEC/DIV" knob to change the horizontal time base
setting and observe the consequent status information change. Rotate
the horizontal "SEC/DIV" knob to change the horizontal time base, and
it can be found that the "Horizontal Time Base" display in the status
bar changes accordingly.
