Long press
button, to enter Short key setting menu, and select
Default
.
Press
button, pops up the prompt to recall the default settings on the screen,
now press
F1
to confirm. The oscilloscope will display the CH1 waveform and remove
all the others. Press F4 to cancel. The table below gives the options, buttons and con-
trols that change settings at default setup.
The following settings do not change when you recall default settings:
Language options, saved settings, saved waveforms, saved reference waveforms,
calibration data.

Horizontal System
Press
Time
button to enter horizontal system menu, use the direction keys to change
the horizontal scale (time base) and the horizontal trigger position. When you change
the horizontal scale, the waveform will expand or contract to the screen center.
1. SEC/DIV Knob
: Used to change the horizontal time scale to magnify or compress
the waveform horizontally. If the waveform acquisition is stopped (by using button),
press
Time
button and
Up
or
Down
buttons to expand or compress the waveform.
2. Horizontal Position Knob
: Used to control the trigger position against the screen
center. Press Time button and Right or Left buttons to move the waveform right or
left. The key resolution vary according to time base. Press "AUTO" key can make the
horizontal position return to zero.
3. Mode: Y
-
T, X
-
Y, Roll, Scan.
Y
-
T
: YT format shows the vertical voltage in relation to time (horizontal scale). Press
Time
-
>Mode
to set.
X
-
Y
: The XY mode is used to analyze phase differences, such as those represented by
Lissajous patterns. The format plots the voltage on CH1 against the voltage on CH2,
where CH1 is the horizontal axis and CH2 is the vertical axis. You may view the same
waveform in XY mode. To perform this operation, stop the acquisition and press
Time
-
>Mode
to change the display mode to
X
-
Y
.
Roll:
In Roll mode, the waveform display rolls from right to left. Trigger or horizontal
offset control of waveforms is available during Roll Mode, and it
’
s only available when
set to 100ms/div or slower. Press Time
-
>Mode to change the display mode to Roll, the
time/div will be changed to 100ms/div automatically
.
Scan
: In Scan Mode, the waveform display scan updates from left to right. In Scan
mode, trigger and horizontal offset control of waveforms are available during Scan
Mode. This mode is only available when set to 100ms/div or slower. Generally, used
for measuring low frequency signal. When the time/div is 100ms/div or slower, the
oscilloscope automatically enters the scan mode
.
