DASYLab 13 // Set t to 0 at triggerevent

[Alfred_M.]

Hello Everyone,

I am trying to measure the preasures that occur when an Airbag deploys.

The measurment works great but i have the following problem:

When my trigger signal (Which is on an Analog input of a OMB-DAQ-3000 Unit) is triggering the measurment 30 seconds after i started the measurement my first data point will be at t=30 seconds.

Is there a possibility to set t=0 at the point of the trigger event? or is there an option to set a counter that starts with the trigger that i could just save with my measured data?

And just FYI i cant restart the measurement on trigger becaurse there is a Save file as... box implementet on programm start.

I hope someone can help me.

What you need to do is to set a counter for time for TTL high and add it as a channel.

Then put a trigger at the counter to trigger when input is above 30 seconds and that trigger will connect to an action that is set for "Measurement: Stop/Restart".

This will restart your app at after 30 seconds you started the trigger.  Obviously, you can use this action in any way you need it.
