The recording period is displayed as a unit of time by default. To
display the recording period as the number of recording samples,
select the
By samples

2. Define sensor properties
Some of the sensors can produce more than one measurement. For example, the
distance sensor measures distance, but MultiLab also calculates the velocity and
acceleration of the measured body in real time. MultiLab automatically displays the
basic measurement of distance, but enables you to display any combination of
distance, velocity and acceleration. Other sensors may only give one measurement,
but can display the data in different units. For example, the acceleration sensor can
display the acceleration in multiples of the gravity acceleration, or in the standard unit
