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.
