screen, where ΔV is the difference between Va and Vb.
The user can move the Va cursor by rotating the multi-
purpose knob by default. Once the location of the Va
cursor is moved to the ideal location, the user can press the
multi-purpose knob (the SELECT button on the 72-2650

rotating the multi-purpose knob in the same way as
moving the Va cursor.
At the Time cursor measurement, the user can repeat
the similar operation as Volt cursor measurement by
using the multi-purpose knob and the SELECT
button on the 72-2650 series DSO.
The Track cursor measurement mode is similar to the
Time cursor measurement except, it will automatically track
any of the voltage level where the time cursor is pointing
at the screen.
After activating the COARSE button, there will be
a quicker response for the cursor movement.
