Key Points:
1. Screen saver: This function extends the life of LCD backlighting system.
2. Expand reference: When changing the volts/div. for channels, the signal
expands or compresses around the signal ground level, or the center of the
screen. When Center is selected, the waveform will expand or compress around
the center of the display. When Ground is selected, the channel ground level will
remain the same position on the display and waveform will zoom about the
ground level.
3. Sticky key: If sticky feature is turned ON, when adjusting positions (CH1, CH2,
MATH, REF, Trig.Lev. and Trig.Pos.), the object will stop at zero position until
next adjustment, for the ease of getting back to initial positions.
4. Key Sets: This function help users to set new code to unlock the keyboard.
