How to Use the Probe Safely
The safety guard ring around the probe body protects your finger against any electric
shock, shown as Figure 4-10.
Figure 4-10 Finger Guard
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

Introduction to the Vertical System
As shown in Figure 4-11, 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 4-11 Vertical Control Zone
1. 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 D C
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.
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.

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, and 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 displa yed, 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 th e attenuation 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 exam pl e, t he attenuation coefficient of the probe is 10:1,
the operation steps is shown as follows:
(1) Press the CH1 MENU button to show CH1 SETUP menu.
(2) Press the H3 m enu selection, the Probe menu will display at the right of the
screen, then press the F2 button to select X10 for the probe.
