Hello,
for a project, we need to measure +/- 12 temperatures in the range -70°C to 100°C, we also need to measure 4 pressures (4-20 mA signal) and +/- 6 ON/OFF contacts.
We would like to display all the measured values in one graph, eventually a graph with more layers.
What is the basic set-up for this and is this anyway possible?
Thanks

Peter

Possible solution??

An USB ADC 11/12 + TC-08?

max samples

Additional question: max samples is only limited by the storage capacity connected computer, so we ca nstore millions of data. Is this correct?

Hi

Thank you for your posts.

Yes, I would say that the USB ADC-11 and the USB TC-08 are the best combination for your requirements. Please note that you will need to use shunt resistors to measure the current with the ADC-11.

The storage ability of the Picoscope software is one million samples per file, however as you can set it to repeat and start a new file every time it can effectively record for as long as the hard-driver memory will allow it.

Hope this helps

Best Regards
Sarah
 

Graphs

Can the different graphs form both units afterwards be pasted in one overall graph?

Hi

Thank you for your post.

Picolog cannot do this but if you export the data to Excel then it is possible there.

Hope this helps

Buffer size & hard-drive memory & zoom in recorded s

Postby Magnus E » Tue Mar 28, 2006 3:29 pm

Hi

The difference between PicoScope 3204 3205 3206 are the bandwidth and the buffer size. What difference makes the buffer size? I mean the recorded signal is stored at the harddrive?

What I want to know is that if I can record a signal over 5 minutes and later go back and zoom in the signal and look for details as transients and “spikesâ€

Hello,

Scopes will store the data in the buffer before transfer to the PC.

Data loggers ransfer the data once it has been converted withour using a large buffer.

Best regards,
Michael
