Hello,

I have a series of voltage values like (12  10.9  10.8  10.7  11  11  11  10.8  10.7  10.7  10.9  11  11  12) on the y axis. Everything that is less than 10.9 is consider to be a voltage drop and I would like to find the time of the drops. As you can see there can be more than one voltage drop, and I have to get the time for every drop.

Sorry for my bad english, and thank you,

Stefan

Hello,

Sorry the same with filled arrays

[ungureanu]

Could you save it for Labview 8.2 :), only if that is not a problem.

Thanks a lot,

Regarding this values (  11  10.8  10.7  10.6  10.9  11  11  12), I need to get the time elapsed from the first value less than 10.9 and the last one (e.g. a drop can last more than 1 sec.) and there are more than one drop. So the question is, how can I see the exact time elapsed from the begining of the drop and the end of the drop.

Thank you for your time,

Stefan

sorry,

it's not what i understood first

Hi Stefan,

I think for this you could just keep track of when you go from a value greater than 10.9 to a value less then 10.9 and then write the value to the array, likewise when you go from a value going from below 10.9 to a value above 10.9 and write that time to the array. Then you can do something like subtract cell 0 from cell 1 to get the time period of the first dip, etc for the following time periods.
