Operating vertical axis
Sets the position of the waveform in the vertical direction.
Pressing OFFSET moves the waveform in
1-division steps in the direction it was last
moved. The offset variable range is as follows:
2 mV to 50 mV/DIV:
±1 V
100 mV to 500 mV/DIV: ±10 V
1 V to 10 V/DIV: ±100 V
OFFSET
VOLTS/DIV
Zoom
Division Enlarges or reduces the waveform based on the GND reference mark
(GND position).
GND position
GND position
Screen center
Used to observe waveform at other than
the center of the screen, for example,
to compare and measure two waveforms.
Pressing the VOLTS/DIV knob allows the vertical gain sensitivity to be
alternately switched between 1-2-5 sequence and Zoom. (The same
function is available using the CH menu.)
If “Zoom” is selected, the setting varies continuously from ´1.00 to ´2.50
(maximum 0.8 mV/div). (Expansion by software)
The waveform is enlarged based on the screen center regardless of the
offset setting.
Screen center
Used to observe waveform at the center of the screen,
for example, to measure a specific part of waveform or
waveform carrying DC bias.
Volts
Turn clockwise (moves up)
Turn counterclockwise
(moves down)
Selects the deflection factor in 1-2-5 sequence.
This function varies depending on the offset setting in the CH menu.
Enlarges or reduces the waveform based on the screen center.
Set the waveform to the screen center with the OFFSET knob. Useful
for observing the exact part of the waveform you are interested in.
Trace
MENU:
Displays the vertical menu.
SELECT: Sets a channel, through which MENU, OFFSET, or VOLTS/
DIV can be operated.
Selects display (On) or non-display (Off) of CH1/CH2/CH3/CH4 waveform.
