Measuring Signals 
Using the Oscilloscope 
as 
a 
Digital Voltmeter 
- 
With ground-refer- 
enced cursors, you can also use the oscilloscope as a digital voltmeter for 
measuring ordinary 
DC 
voltages (Figure 3-34).

Levels with Cursors 
Measuring Time 
with the 
Graticule or Cursors 
Make period or other time measurements between two points on a wave- 
form using this basic procedure: 
Step 
1: 
Display the signal on screen so that the first point you wish to 
measure from is on screen. 
Step 
2: 
In 
NON-STORE 
mode adjust the time base to place the other 
horizontal point on screen and use the graticule lines to make the mea- 
surement 
- 
or go to 
STORE 
mode and use the rest of this procedure. 
Step 
3: 
In 
STORE 
mode, position a cursor on the first point of the 
waveform with the cursor control. 
Step 4: 
Push the 
CURSORS 
knob in to select the other cursor and 
position it on the second point. (On 4K  or magnified displays an acquisi- 
tion window indicator at the top of the display shows where the cursors 
are relative to the entire record length.) 
Step 
5: 
Note the 
A 
time (change or difference in time) readout in the 
upper right corner of the display.
