the knob to automatically set the parameter to 0.
9. Trigger Type
Display the currently selected trigger type and trigger condition setting.
Different label is displayed when different trigger type is selected.
For example, represents triggering on the rising edge in “Edge” trigger.
10. Trigger Source
Display the trigger source (CH1 to CH4, EXT, EXT/5 or AC Line) currently
selected. Different label is displayed when different trigger source is selected
and the color of the trigger parameter area will change accordingly.
For example, denotes that CH1 is selected as the trigger source.
11. Trigger Level
 at the right of the screen is the trigger level label and the trigger
level value is displayed at the upper-right corner of the screen.
 When using TRIGGER LEVEL to modify the trigger level, the
trigger level value will change with the up and down of .
Note: in slope trigger, there are two trigger level labels ( and ). For
detailed information, refer to “Vertical Window” on page 5-14.
12. CH1 Vertical Scale
 Display the voltage value per grid of CH1 waveform vertically.
 Use VIRTICAL SCALE to modify this parameter.
 The following labels will be provided according to the current channel
setting: channel coupling (such as in AC coupling), bandwidth limit
(such as when bandwidth limit is enabled) and input impedance
(such as when the input impedance is 50 Ω).
13. CH2 Vertical Scale
 Display the voltage value per grid of CH2 waveform vertically.
 Use VIRTICAL SCALE to modify this parameter.
 The following labels will be provided according to the current channel
setting: channel coupling (such as in AC coupling), bandwidth limit
(such as when bandwidth limit is enabled) and input impedance
