Cursor Measurements 
Cursors allow you to make precise digital measurements 
on waveforms. Cursors are disabled for 3-phase power 
measurements. 
Horizontal Cursors 
Use horizontal cursors to measure the amplitude, high 
and low value, or overshoot of a waveform. 
To use the cursors for a voltage measurement: 
1. Repeatedly push  until all menus and 
secondary button bars close. 
2. Push 3 to select CURSOR ON. 
3.  Push 1 to select . Observe that two horizontal 
cursor lines are shown on the screen. 
4. Push 2 to select the upper cursor. 
5. Use 
YZ to move the position of the upper cursor 
on the waveform. 
6. Push 2 to select the lower cursor. 
7. Use YZ to move the position of the lower cursor 
on the waveform. 
Note 
Even when the key labels are not displayed at 
the bottom of the screen, you can still use the 
arrow keys. 
The readout shows the voltage difference between the 
two cursors and the voltages at the cursors in relation to 
the zero icon (-).
