Press F2 Channel key first, then select OFF to make a Close setting on channel.
Press F2 Channel key first, then select ON to make an Open setting on channel.
7.1.3. Setting the probe attenuation
To prevent excessive input voltage, we recommend you to set the probe attenuation level to the 10X position to prevent
excessive voltage.
After attenuating the probe level by 10:1, you also need to magnify the display level by 10X to match the displayed
amplitude with the real amplitude.
Press F3 Probe to adjust the probe attenuation level.
Probe attenuation factor and the corresponding menu setting
7.1.4. Setting of Inverted Waveform
Inverted waveform: The displayed signal reverses 180 degrees relatively to the ground potential.
* Press F4 to set Inverted as ON to start Invert
* Press F4 again to set Inverted as OFF to close Invert
7.2. Setting the Trigger System
The Trigger defines the time when the acquisition of data and display of waveform start. If it is set correctly, the trigger can
turn an unstable display into a significant waveform.
When starting the acquisition of data, the oscilloscope collects sufficient data to draw the waveform at the left side of the
triggering point. With waiting for the triggering condition, the oscilloscope is gathering data continuously. After a trigger is
detected, the oscilloscope gathers enough data continuously to draw the waveform at the right side of the triggering point.
To make a trigger mode setting, do the following:
1.) Press the MENU key and the function menu appears at the right of the screen.
2.) Press the MENU ▲ or MENU ▼ key to select TRIG MODE and five items selectable are displayed at the bottom of
the screen.
3.) Select from F1 to F5 key to make a different setting.
4.) Press OPTION and left bottom display as below during edge trigger and video trigger:
◄/► – Time ◄/► – Time Base
▲/▼ – Trig ▲/▼ – Trig
5.) Press ▲ (OPTION) or ▼ (OPTION) to adjust trigger vertical position, Press ◄ (OPTION) or ► (OPTION) to
adjust time base horizontal position or adjust horizontal position.
