• Fine adjustment: Use the icons at the right side of Scale or rotate the knob to

further adjust the vertical scale within a relatively smaller range to improve

vertical resolution. If the amplitude of the input waveform is a little bit greater

than the full scale under the current scale but a little bit lower if the next scale is

used, fine adjustment can be used to improve the amplitude of waveform

display to view signal details.

• Coarse adjustment: Use the icons at the right side of

Scale or rotate the knob to

adjust the vertical scale in a 1-2-5 step sequence, i.e. 500 μV/div, 1 mV/div, 2

mV/div, 5 mV/div, 10 mV/div...10 V/div.

5.3 To Adjust the Vertical Offset

Vertical offset indicates the offset of the signal ground level position of the waveform

from the vertical center of the display. Its unit is consistent with the currently selected

amplitude unit (refer to "

To Specify the Amplitude Unit

"). Adjusting the vertical offset

moves the corresponding channel's waveform 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 probe ratio and

vertical scale.

When CH1 is turned on and activated, you can adjust the vertical offset with the

following methods:

• Rotate the Vertical

POSITION knob at the right section of the front panel to

adjust the vertical offset within the adjustable range. Rotate this knob clockwise

to increase the vertical offset or rotate it counterclockwise to reduce the vertical

offset. Pressing the knob can quickly reset the vertical offset (set the vertical

offset to 0).

• Enable the touch screen function, and then adjust the vertical offset with the

drag gesture. For details, refer to "

Drag

• In Vertical menu, click or tap the Up and Down arrow icon at the right side of

the input field of

Offset to increase or decrease the offset value or use the

corresponding multipurpose knob to set the value. You can also click or tap the

input field to input a specific value with the displayed numeric keypad.
