Efficient way of having multiple user-defined step sizes in a ramping sequence

[Nio]

Hi guys,

I've written a basic automated Current-Voltage VI which works rather nicely. As I'm sure you all know, all the program does is ramp the output voltage through a user-defined range, in user-defined increments.

However, there are cases where the user may wish to have a high density of points over a given range, and fewer points over a less significant area. As such, the user must be able to input the step-sizes they would like and the voltage ranges over which they are to be used. I should like for my VI to allow the user to specify as many of these differing incremental sizes as they wish, but cannot for the life of me think of an efficient way of doing this!

Can anyone help?


All the best,

Jamie

Nobody has any ideas?

I think we need to see your code before offering suggestions.

Ok, here's the code. I'm a newbie, so it's probably not the most efficient VI around.

There are two Keithley VI's in the sequence structure, one for the voltage source and the other for the ammeter.

Hope this helps!

Could you save that as a 7.0 format?? I should have mentioned that on my last post.

[Nio]

I have 7.1; how would I go about doing that?

File, Save with options, Save for previous

To make things more straight forward, I've removed the rest of the VI and isolated the ramping section for you to look at. It's in 7.0 format, as requested 😉

Here is an option with new increment values inside a case structure. There are a several methods that you could use.

Thank you very much! That's exactly what I was looking for 🙂
