Reading 115vac 400Hz

[Kimlorentz]

I am working on reading 115vac 400Hz power supply using an PXI-4472.

I got it working, but if the signal gets lost the loop crashes.

How do I stop it from doing this?

Anyone got an example of reading ac voltage even if its 0volt?

You should attach your VI so people can have a look...

I will do it tomorrow 😏

In adition to the vi, it would be interesting to know how you are reducing the 115 VAC to a level that is compatible with the PXI-4472.

Got it working.

It was my sampling settings that was wrong and how I put my code together.

For reducing 115vac i used resistors (ATTENUATOR 20:1).

OLD vi. code

New vi. code

EDIT!!

The ATTENUATOR is an 40:1 and not an 20:1.
