Timer Reset to Zero?

[Jesse Campbell]

We are using Labview 8.5 and a Keithley DAQ system. Measurements are being taken and written to a spreadsheet. We have a boolean button that we push and starts a case structure to take steady state data (temperature readings). We are having trouble getting the elapsed time timer to reset to zero after 60 seconds. The elapsed time will keep reading from when the button was last pushed and we would like to have it start at zero each time the button is pushed. Thanks for any help.

Hi Jesse,

I didn't use the elapsed time vi, but would something like this work for you?

Sorry I attached the jpg, not the Vi, so you can's see the other half of the case statement.  Attachemnt is in LV 8.2.

Since the default behavior of the elapsed time function is to auto reset when the target has been reached, you should really post your code so someone can see what you've done to change the behavior.

Here is the original code. The elapsed timer inside the case structure holds the elapsed time value since the start steady state data button has been pressed.

Of course you don't see the value change. You have the indicator inside the case statement and that code stops running/updating the indicator as soon as the case becomes false. Just move the indicator outside the case statement if you want to false case to set the indicator to 0.
