• Vertical “POSITION” knob
1. Use the Vertical “POSITION” knobs to move the channel
waveforms up or down on the screen. This button’s resolution
varies based on the vertical scale.
2. When you adjust the vertical position of channel waveforms,
the vertical position information will display on the bottom
left of the screen. For example “Volts Pos=24.6mV”.
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 “Volts/div” Knob, you can switch
“Volts/div” option between “Coarse” and “Fine”. The
vertical scale is set by the 1-2-5 step in Coarse mode.
