When you are executing a program with Duration DAT, you have the option to set the timer value to 00:00. Selecting this will immediately store "00:00" as the recorded value for that specific execution.
At any time, you can select the "Start Timer" or "Restart" options to change the duration value.
However, please note that this functionality is now only available when the DAT (Data Acquisition Tool) is configured not to capture data manually. If the manual capture option is selected within the DAT setup, these timer controls will be disabled.
Then, you will be able to manually define the time as 00:00.
