To use Measure, simply Press Measure button would activate MEASURE menu.
Press F1 next to Source/Type to allow you to switch between Source and Type.
Source is the signal from the channel which user to carry out a measurement, and
Type is one of the 20 measurements user wants Oscilloscope to work out. Under the
Type as you can see in Fig. 5-43 is what the actual measurement reading is. The
reading would show sign of "?" if there isn't a measurement can be worked out from
the source signal. As in Fig. 5-43, both Channel1 and Channel2 are chosen as source,
measurements are taken for Frequency, Pk-Pk value, Mean and RMS.

Abbreviation Descriptions
Vpp Peak-to-Peak Voltage.
Vmax
The maximum amplitude. The most positive peak voltage measured over
the entire waveform.
Vmin
The minimum amplitude. The most negative peak voltage measured over
the entire waveform.
Vamp Voltage between Vtop and Vbase of a waveform.
Vtop Voltage of the waveform's flat top, useful for square/pulse waveforms.
Vbase Voltage of the waveform's flat base, useful for square/pulse waveforms.
Overshoot Defined as (Vmax-Vtop)/Vamp, useful for square and pulse waveforms.
Preshoot Defined as (Vmin-Vbase)/Vamp, useful for square and pulse waveforms.
