In the coordinate grid, there are two types of measurement rulers, which allow the
amplitude and time duration of a waveform to be measured precisely. They are useful
when determining signal characteristics such as amplitude at specific points, the cycle
time (duration) and frequency.
The vertical Time Ruler - Tap the Ruler Activator in the bottom left corner of the grid
and drag it across the screen to the desired position. A Time Ruler is generated.
The horizontal Signal Ruler - The Signal Ruler can be generated in the similar way by
clicking the Ruler Activator in the top right corner and dragging it downwards.
When dragging the Measurement Rulers, a Ruler Table showing time and voltage
values for the corresponding channels will be displayed. The Delta icon refers to the
absolute difference between the values of the rulers, which can be locked by tapping the
Lock icon. Tap the X button in the upper right corner of the ruler table to delete all rulers.

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.
