16.4.4 Measurement Rulers
The Measurement Rulers allow the voltage and time duration of a waveform to
be measured precisely. There are 2 kinds of measurement rulers: the vertical
Time Ruler and the horizontal Voltage Ruler.
Tap on the Ruler Activator on the bottom right corner of the measurement grid
and drag it across the screen to the desired position, a Time Ruler is generated.
The Voltage Ruler can be generated in the similar way by clicking the Ruler
Activator on the top left corner and dragging it downwards.
When Measurement Rulers are generated, 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 2 rulers, which can
be locked by tapping the Lock icon.
