Plot Area
The Plot Area is where the signals are displayed after the oscilloscope samples and
records them. Notice the graph made up of 10 divisions horizontally and 8 divisions
vertically. These divisions can be used to measure the signal’s voltage (vertical divisions)
and time duration (horizontal divisions). With the OPTAscope 81M you can have one or
two signals in the Plot Area (Figure 1-5).

Don’t be afraid if you change the settings to an unknown state. You can always reload the
factory default settings. To do this, select File → Load Factory Default Settings from the pull
down menu. Follow the directions and this will bring you back to a default installation state.
Resetting to defaults will erase your calibration data and can reset your COM port setting if
you answer yes to both questions.
