MEASURING PHASE USING THE CURSORS

91 92
In this example you will use the cursors to measure the
phase difference between the waveforms on INPUT A and
B. Use the two waveforms from the dual input three-phase
measurement in the previous exercise. Cursors allow you
to make accurate digital measurements. It is advised that
you first press to freeze the waveforms to be
measured.
➀
Measure the two sine wave waveforms as explained
in the previous example.
➁
Return to the main menu.
➂
Set the test tool to Scope mode.
➃
Freeze the display; HOLD appears in the upper right
display.
➄
➪
Activate the Cursor readings.
