How to save data with Write to Measurement File

[Matt_@_ICS]

I have a LabView program that I'm using to collect data from lab equipment.  I am using the Write to Measurement File  VI, (WMF), to save the data into a text format that I can use.  The problem that I am having is that it saves at what looks like a rate of 10 saves per second.  I am using the Save to Series of Files option in the WMF preference screen, and I have it set to terminate and start a new file after every 1 segment.  What I need to be able to do is save one set of data points, or one segment, every 15 minutes.  I think this is accomplished using the Enable imput on the block diagram, but I'm not sure how to set that up.  It would be ideal if this could be a control setting that can be changed on the Front Panel, but it would be ok if it's a constant on the block diagram.

Any help would be appreciated.  Thank you.

To answer your basic question, you can use the Elapsed Time to control how often you want to do a save.

You have some other issues with the VI you posted. Your event structure needs to be in a while loop, and you can get rid of the whole sequence structure. It serves no purpose at all.
