Key Points

Screen saver: This function extends the life of LCD backlighting system.

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.

Sticky key: If sticky feature is turned ON, when adjusting positions (CH1,

CH2, CH3, CH4, MATH, REF, Trig.Lev. and Trig.Pos.), the waveform will stop at

zero position until next adjustment, for the ease of getting back to initial

positions.
