3. Select the desired recording rate in the Select rate drop list.
4. Select the Scroll option if you want the graph window to scroll as
the data recording progresses.
5. Select the desired data recording mode in the Select recording
mode drop list.
6. Click Next to move to the third step:

7. Select the desired length of the recording period in the Select
recording time drop list.
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 option. The number of samples is calculated
with the following formula:
Total recording samples
Recording period Recording rate
= ×
8. To start the data recording only when a specific time or
measurement condition has been met click Triggering to open the
triggering dialog box (see page 58).
9. Click Finish to complete the setup and to send the setup command
to the MultiLogPRO.
2. Defining 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
