The X-axis and Y-axis can be zoomed using your fingertips. The waveform can be
zoomed during or after capturing the signal.
Measurement Rulers
The coordinate Rulers allow the voltage 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.
There are three types of measurement rulers: the vertical
Time Ruler
, the
horizontal
Voltage/Current Ruler
,
and
the vertical
Angle Ruler
.
Tap the
Ruler Activator
in the lower left corner of the grid and drag it across the
screen to the desired position. A
Time Ruler
is generated.
Tap the
Angle Activator
in the lower right corner of the grid and drag it across the
screen to the desired position. An
Angle Ruler
is generated.
The two angle rulers are positioned to mark the start and end of a cycle. By default,
the start and end angle values are 0° and 720°, which can be configured in the
Phase Setting box.
The
Voltage/Current Ruler
can be generated in the similar way by tapping the
Ruler Activator
in the upper right 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 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.
