Picolog won't sample faster than 8S/sec

Postby tomzamboglou » Fri Jul 16, 2010 4:13 pm

Hi.

I have been trying to get my picolog recorder to sample outputs from pressure transducers as fast as possible. I have set sampling rates at 25 and 50 ms, however my output data always displays as having been taken at 125ms (8 samples every second).

Do you know why this might be happening and how I can increase my sampling rate?

Regards,
Tom

Hi Tom,

What product are you using, as this may dictate how your readings are taken.

My suspicion is that your are using realtime continuous mode which relies upon the PCs to dictate the timing and as such you are not always guaranteed the time you request.

Kind regards

Hi Ziko,

I'm using the picolog 1012 recording on "realtime continuous".

Another thing, try using the latest software as there was an issue with one of the earlier versions of the software. As 25ms should be fine on a Picolog 1012 even in realtime continuous mode.

Hi Ziko,

Thanks. I just bought the 1012 about 4 weeks ago. Is there somewhere I can download the latest software?
