how to get final time

[signal29]

hi everybody we need some help

we are trying to find the delay the between two signal peak  . now i am using ELAPSED TIME VI from the timing pallet that counts the delay,in an increasing manner, and the VI is reseted after the second peak is detected  

but what i need is the exact final delay time instead of the increasing time delay count , can kindly anybody help me.

you can use Elapsed Time VI in conjuction with the tick count. The elapsed time VI will reset with the first peak. But the Tick Count will give you the whole span of time till the second peak when the whole VI is stopped. A minus function between the tick count time and elapsed time VI value will give you the time between the two peak.
