Timed Recording
This option allows indefinite data collection that can be programmed to run until the operator manually
stops recording. It may be used unattended on a single leaf for long periods, or the user may choose to
pause recording to either change Control Setpoints or sample different plants or leaves.
Again, select Recording - Begin from the CIRAS-2 main menu. In the Select Recording Options dialog
click in the circle next to Timed and then click OK. There are two Timed Recording Options:
1. Recording single measurements
2. Recording blocks of measurements
Both options have an initial Settle Time to allow for stabilization and a forced Zero before recording
begins. Both options can include recording only after a Steady PN (assimilation rate) has been reached,
allowing you to determine your own acceptable level of variability associated with the plant or species of
interest.
