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
In the coordinate grid, there are two kinds of measurement rulers, which 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.
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 Y-axis Ruler - The Ruler can be generated in the similar way by
tapping the Ruler Activator in the upper right corner and dragging it downwards.
NOTE
The horizontal Y-axis ruler varies according to the settings of the voltage, current,
frequency, duty cycle, etc.
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.
