The volts/div for each channel are adjusted using the large Volts/Div
adjust knobs. Turn them counterclockwise to increase the volts/div; turn
them clockwise to decrease it. The position knobs control the vertical
position of the waveforms on the screen by moving the ground position of
each waveform up or down.
Math () Menu
The math menu key brings up only three choices. All three are self-
explanatory:
 Off
 Channel 1 + Channel 2
 Channel 1 – Channel 2
Timebase / Horizontal Controls
The delay knob adjusts the horizontal position of the display left
or right by moving the t = 0 point. If the delay is adjusted, then the pair
of solid triangles at the top and bottom of the display (mentioned
previously) will move accordingly. The display point will retain a pair of
open triangles to mark its position. The display point may be set to either
one graticule in from the left side of the display or to the center of the
display.
The time/div (or timebase) is adjusted by the large Time/Div knob. Turn it
counterclockwise to increase the timebase, clockwise to decrease it.
Pressing the Main/Delayed menu button will bring up the following items:
 Horizontal mode: main / delayed / XY
 Vernier off/on
 Time reference position left/center
The Main horizontal mode is the standard volts vs. time oscilloscope display mode. The
Delayed mode splits the screen into two; in the top portion are the original waveform(s), and the
bottom holds a time-zoomed version of that waveform(s). The Time/Div and Delay knobs
control the window size and position of the zoomed portion.
