a. You should consult the applicable technical manual for specific operating
instruction covering your particular instrument.
For proper use of any
oscilloscope, you must consult the instruction regarding turn on and operation.
Improper operation of the oscilloscope may cause damage to the instrument.
b. After the oscilloscope is properly set up, allow time for the instrument
to warm up before you start to use it for checking waveforms. Make certain there
is a good reference signal on the screen.
c. A couple of examples of a good signal, which you should be able to obtain
at this point, are shown in Figure 2-3. If any other picture is obtained, adjust
the appropriate scope controls until the proper picture is shown on the screen.
