5.4 To Adjust the Vertical Offset
Vertical offset indicates the offset of the signal ground level position of the waveform
from the screen center in the vertical direction. Its unit is consistent with the currently
selected amplitude unit (refer to "
Amplitude Unit
"). When adjusting the vertical offset,
the waveforms of the corresponding channel moves up and down. The vertical offset
information (as shown in the following figure) in the channel status label at the
bottom of the screen will change accordingly.
The adjustable range of the vertical offset is related to the current input impedance,
probe ratio, and vertical scale.
When CH1 is turned on, you can adjust the vertical offset with the following four
methods:
• Rotate Vertical OFFSET that corresponds to CH1 to adjust the vertical offset
within the adjustable range. Rotate this knob clockwise to increase the vertical
offset, and rotate it counterclockwise to reduce the vertical offset. Pressing down
the knob can quickly reset the vertical offset (set the vertical offset to 0).
• Menu setting: Press > More > Offset, and then the numeric keypad is
displayed. Input the offset value with the numeric keypad.
• Enable the touch screen function, and then adjust the vertical offset with the
drag gesture. For details, refer to the "
Drag
" section.
• Enable the touch screen function, and tap the channel status label at the bottom
of the screen. The following window is displayed. Tap the
icon at the
right side of the Offset input field to decrease or increase the offset. You can also
tap the input field to input a specific value with the displayed numeric keypad.
