Recording a channel value every 30 minutes

Hello,

I would like to know if I can recorder a channel value every 30 minutes or 1 hour during my registrations. I don't mean a medium value, but the exact channel value. I find the "LACHT VALUE MATH" but I don't know i can set the time lapse.

thanks a lot.

Hi!

You can do that by using sequence. Go to Setup file > New Sequence.

Here is an example:

Hello!

thanks for your help. If I understand, with this sequence I can take a recorder every 30 minutes with lenght of 30 minutes, but I would like to recorder only one data every 30 minutes. Thank you a lot.

No, the record lenght is only 10 seconds and you can change it to longer or shorter if you wish to. Under Delay function after StartStoring.

Here's another way - without using sequencer and only taking a single point measurement.

Generate a signal in Math Formula that is a sine wave with a period of 30 minutes. TrigChan = sine(1/18000).

Then create a Latch value Math channel that is triggered by TrigChan = 0 (ie Criteria Channel = TrigChannel and Criteria Limit =1)

The the output of the latch value math will be your one sample every 30min.

Saves messing with sequencer!.

Typographic Correction: Criteria Limit =0; then it triggers a sample every time the TriChan signal crosses through zero going positive.
