How do I let the user input values at specific times ?

[Abdulellah]

Greetings Gentlemen,

I'm trying to make a program which can take some values from the user at specific times only. 

The goal of the program is to formulate a calibration equation for the Thermocouple. 

Thermocouple's output is in millivolt, and it's taken from the Digital Multimeter after each " t " minutes.(x-axis readings)

I want to prompt the user at these times to input the value of the temperature.(y-axis readings)

I want to organize all of the input in a table(array?) and let LV do the graph and output the equation.

Can LV do all of this? 

Thank you very much

Yes it can. I would recommend you look at the examples for how to implement a state machine. This will allow you to prompt the user and specific times when you need the data. You can prompt the user by using dialog boxes or by simply showing/hiding the controls at the appropriate times.

Can you tell me where can I find it?

If you combine this with a shift register where you keep the last time stamp, you can check the elapsed time by substracting the current time by last time stamp and see if its bigger then a certain value...
