Data logger - only ever half hour

[David Student]

Hello all,

I need quick help, probably is it easy question but I don't know how to do it. I need create easy data logger for measurement electrical power and temperature of induction motor. Functions aren't problem, but I don't know how set data logger to save after every half hour.( Saving frequency = 2 save per hour). Could you someone please help me how to do it? Thanks a lot. David

Have you looked at the Timing palette? A simple way would be to use the Elapsed Time function wired to a case statement.

The best way to learn would be if you posted what you tried and tell us in what way it didn't work.  Then we can show you how to correct it.

Solved. It was really stupid mistake. I forgot that I set saple to read on 1000...So I measured all the time well, I just added average function....Thank a lot for your efforts.
