Functional Description
VERTICAL System (cont’d)
Knobs in the
« VERTICAL » mode
Vertical “POSITION”
knob
1. Use the Vertical “POSITION” knobs to move the channel waveforms
up or down on the screen.
2. When you adjust the vertical position of channels waveforms, the
vertical position information will be displayed on the bottom left of
screen.
3. Press the vertical “POSITION” knob to set the vertical position to
zero.
Volts/div knob
1. Use the “Volts/div” knobs to control how the oscilloscope amplifies or
attenuates the source signal of channel waveforms. When you turn
the “volts/div” knob, the oscilloscope increases or decreases the
vertical size of the waveform on the screen with respect to the
ground level;
2. When you press the “Volt/div” Knob, you can switch “Volt/div” option
between “Coarse” and “Fine”. The vertical scale is ensured by the
1-2-5 step in Coarse mode. In the fine mode, the knob changes the
Volts/Div scale into small steps between the coarse settings.
