Making Cursor Measurements

Cursors allow you to make precise digital measurements
on waveforms. For 3 phase power measurements cursors
are disabled.

Using Horizontal Cursors on a Waveform

To use the cursors for a voltage measurement, do the
following:
From Scope/Meter mode, display
the Cursor Key functions:
Press to highlight
that two horizontal cursor lines
are displayed.
Highlight the upper cursor.
Move the upper cursor to the
desired position on the screen.
Highlight the lower cursor.
Move the lower cursor to the
desired position on the screen.
2-22
. Observe
The readout shows the voltage difference between the two
cursors and the voltages at the cursors in relation to the
zero icon (-). (See Figure 2-18).
Use horizontal cursors to measure the amplitude, high and
low value, or overshoot of a waveform.
Note
Even when the key labels are not displayed at the
bottom of the screen, you can still use the arrow
keys.
