Ⅳ、Menu operation (short press key to downward selection menu,
short press key to Upward select the menu)

1. Gear Selection ：
Press key to increase Vertical gear, press key to reduce Vertical gear.
Press key to increase Level gear, press key to reduce Level gear.
Long press key to up adjust the vertical position of Y axis, long press key
to down adjust the vertical position of Y axis.
Long press keys to Left adjust the horizontal position of X axis, Long press
keys toRight adjust the horizontal position of X axis.
2. Mode selection ：
Press or to select trigger mode: rising edge trigger / falling edge trigger.
Press or select sync mode: there are "AUTO", "NORM", "SING" and "NONE"
four synchronization mode can be chosen.Where "AUTO" is automatically synchronized
scanning mode, when the input signal is not satisfied when the trigger condition, still be
able to display signal waveform; "NORM" is a common scanning mode, when the input
signal is not satisfied when the trigger condition, do not display signal waveform; "SING"
is single scan mode, the signal is triggered scan sampling and display after the 1 time,
automatically enter the suspended state, Restart after press key; "NONE" is
the random sampling display mode, this mode don’t stop wave scanning.
3. The trigger level adjustment：
Press or key to up and down adjust Trigger level.
4. Measurement of the cursor 1：
Press or key adjusted up and down vertical cursor 1
Press or to adjust the level of the cursor around 1
