Key Points

Screen saver: If oscilloscope is free for a pointed time, screen saver

function can be used. 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, 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.
