the LCD informing you of this.

Figure 1–18: Display of a Stored Waveform
When pushed on, the VIEW DIFF button displays the difference between the current
waveform and the stored waveform as a dotted line. If no waveform has been stored,
a message will appear. The difference waveform is made by subtracting each point
in the stored waveform from each point in the current waveform.
NOTE. If the two waveforms are identical (e.g., if STORE is pushed and VIEW DIFF
is immediately pushed) the difference would be zero. Therefore you would see the
difference waveform as a straight line.
The VIEW DIFF waveform will move up and down with the current input as you
move the

POSITION control. Any of the waveforms may be turned on or off
independently. You might want to turn off some waveforms if the display becomes
too busy or confusing.
