To Adjust the Vertical Scale
Vertical scale indicates the voltage value per grid in the vertical axis of the screen. It
is often expressed in V/div. While you adjust the vertical scale, the display amplitude
of the waveform would enlarge or reduce. The scale information of the channel
status label (e.g. as shown in the following figure) at the lower section of the screen
would change accordingly.
The adjustable range of the vertical scale is related to the currently set probe ratio
and input impedance. By default, the probe ratio is 1X and the input impedance is 1
MΩ. In this case, the adjustable range of the vertical scale is from 1 mV/div to 10
V/div.
When CH1 is turned on, you can adjust the vertical scale with the following three
methods:
⚫
Rotate Vertical SCALE that corresponds to CH1 to adjust the vertical scale
(clockwise to reduce the scale and counterclockwise to increase).
⚫
Enable the touch screen function and adjust the vertical scale with the pinch &
stretch gesture on the touch screen. For details, refer to the "Pinch & Stretch"
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 Scale input field to decrease or increase the scale. You can also
tap the Scale input field to input a specific value with the displayed numeric
keypad.
In the vertical control area (Vertical) on the front panel, press
Vertical SCALE
to adjust the vertical scale in "Coarse" (by default) or "Fine" mode. You can also
press 1

→
Fine to enable or disable fine adjustment.
⚫
Fine adjustment: Rotate Vertical SCALE 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 and the amplitude would be 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.
