Go to Setup->Load… and find the setup that is closest to the measurement you wish to perform in the list box. This will load the WinMLS settings needed for this type of measurement. Most setups also contain a wizard that will guide you through the measurement.
Start the measurement by clicking the button (or from
Measurement->Start). If you want to cancel the measurement before it
is finished, click the
button (alternatively the Esc key or
Measurement->Cancel).
