• “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 set by the 1-2-5 step in the Coarse.
Increase in the clockwise direction, decrease in the counter
clockwise direction. In the fine mode, the knob changes
the Volts/Div scale in small steps between the coarse
settings. Again, increase in the clockwise direction,
decrease in the counterclockwise direction.
