Selecting the Acquisition Mode
Setting Up Timed Acquisition Duration
A timed acquisition starts when you start the process, and continues for the
time you have previously specified.
To set the duration for your acquisition:
Click inside the Timer edit box of the Data Acquisition tab and enter the
value (or use the arrow buttons next to the list to adjust it).
If you are using the numeric box, enter the value in seconds
(for example, 120 seconds if you want to enter two minutes).
The acquisition length displayed for a single acquisition includes the time
set in the Settings tab for the acquisition, plus the time needed to transfer
data according to the sampling rate selected. During the acquisition, you
will notice the message Acquisition in progress, then Data transfer in
progress in the Instrument function tab. If you click Stop before the data
transfer is complete, you will lose your acquisition data.
