Zero Baseline
The zero baseline is marked as the 0 value in the Y-axis, showing the base level of each
channel waveform. After the channel is selected, the zero baseline can be adjusted by
dragging the baseline marker up/down along the Y-axis, or dragging the waveform
up/down or moving the screen up/down in the grid.
NOTE
Tap the baseline marker to make the vertical scale line thicker. In this case, the channel
is selected. Tap the baseline marker again to unselect and the waveform cannot be
dragged.
