Exit (Quit) Daqarta

Controls: File Menu >> Exit
Macro: DqaExit

You can exit Daqarta from the File menu with ALT+F, X, or from the [x] at the upper right of the main Daqarta window, or directly via ALT+Q (for Quit). Regardless of which method you use, you will be asked to confirm this unless you have unchecked the Confirm Exit option in the Preferences dialog.

If you confirm that you do want to exit, you may be asked if you want to save certain changes you have made during operation.

If you have changed the Generator setup in any way (even if you later changed it back) you will be prompted to save the changed setup unless you have unchecked Prompt Setup Change in the Preferences dialog.

If all you have changed in the Generator setup is the volume, you can avoid the confirmation prompt by unchecking only Prompt Volume Change instead. This is useful where you have a standard setup and a test protocol that involves a standard initial volume that you change during the session, such as for measuring hearing thresholds.

If you have made any changes affecting calibration, such as Range, External Gain, or User Units, you will be prompted to save those as well.


Macro Notes:

DqaExit= (value ignored if given) will initiate the exit sequence described above. If you are using this macro as part of an automatic shutdown after a test, remember that you will also need to uncheck Confirm Exit in the Preferences dialog or the shutdown will require operator intervention.

Likewise, if the operator made manual changes to Generator parameters (not made via macros), you will also need to uncheck Prompt Setup Change.

Manual changes to calibration parameters will always result in a save prompt on exit.

Macro-initiated changes never cause exit prompts.
