Hi

I may have posted my question in the wrong spot yesterday. So this is try #II.

I am interested in the USB TC-08. The specifications listed at the website don't include the possible time intervals which you can choose between the taking of data, nor the number of data which can be stored. I tried to download the instruction manual (.PDF), but it didn't work.

I would appreciate knowing this information.

Many thanks,

Carl S

*********************************

I was able to download the data sheet, which said that up to a million data can be stored, and that the minimum time interval is 0.1 second. So can I store data every minute? Every 10 minutes? Every 30 minutes?

Thanks

Hello Carl,

Thank you for your post.

Let's look at this in terms of hardware and software.

The USB TC-08 has a conversion time of 100ms per active channel, 0.1s time interval. Increase by 100ms for every channel you activate say 4 and the cold junction, 5 in total, The conversion time becomes 500ms intervals. This is the limitation of the hardware.

PicoLog can sample at millisecond interval in streaming modes. Our TC-08 can only sample at 100ms at its fastest. So you can tell PicoLog to get a sample every millisecond but it will only return the last converted measurement from the TC-08.

Now, PicoLog can store up to 1 million samples in a single log file. This is the limitation of the software. PicoLog can record a new log file, sequentially numbered, to give you minimum breaks in recording. This would also depend on the size of your storage device. For example, 1 million samples on eleven channels is roughly 47 MB.

I hope this answers your questions.

Please don't hesitate to contact us if you have any further questions.

Best regards,
Michael
