disable the channel. For example, if CH1 and CH2 are enabled and CH2 channel
setting menu is displayed on the screen, then if you need to disable CH1, first activate
CH1, and then press or enable the touch screen to tap CH1 channel status label to
disable CH1. If CH1 is disabled, the channel status label is shown in the following
figure.
5.2 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.
Vertical Scale
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 then 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 input
field to input a specific value with the displayed numeric keypad.
