Hi,

I have the ADC11/12 USB with the latest version of PicoLog. I am sampling in Fast Block for 5 seconds at a sampling rate of 5kHz using 3 channels. After the sampling is finished, the PLW Spreadsheet window displays normal sample data for a very short period of time, then all the values after that are 0, including the time. I have tried two different computer and even tried reducing the sampling rate. Neither of the two computers are slow, both with more than 1GB RAM and the CPU is a 3GHz Pentium 4 or 1.86GHz Pentium M Laptop.

Please Help
Regards
Ajay

Hello,

It sounds like the ADC11 is returning a short number of samples in the block. YOu will need to increase the number of samples in the block sample to get more samples in the spreadsheet.

Best regards,
Michael

I have tried all sorts of values for "No of samples" and "Total Time" with no luck. I need to get this problem solve ASAP other wise i will have to purchase another ADC product. I have taken some screen shots of the problem. I am using 5000 samples over 5 seconds. That is a sample every 1ms or a sampling rate of 1kHz. I am using 3 channels. In the screenshots, after about 1.5 seconds the sample readings are all zero and so is the time value.

I have exactly the same problem with my USB ADC-11/10 and it need to be fixed ASAP. I have important test on Thursday 7/12 and I missed a lot of time last week because of this problem. I use almost the same settings as Ajay, Fast Block and around 5000 samples in 5 seconds. I also tried many different settings between 2-10 seconds and 50-50 000 samplings but the same problem occurs. Usually the first run works fine and if a turn of the PicoLog Recorder and disconnect the data logger and turn of the power to all the meters I am able to do a second run. But otherwise during the second run zero values starts to occur after a random number of samplings/time. And if I do a third and forth run without the turn of procedure I usually get fewer samplings after every run before the zero values starts to occur. But very randomly and sometimes after only 4 samplings. I have tried with a couple of different computers but I still have the same problem. Let my know if you need my data sheets as Ajay gave you.

Hi

I have spent a while trying to replicate this but without any success.

Can you also send me over the file you are using to tech@picotech.com? In the meantime try a version from our software archive:

See if this helps at all.

Best Regards

Is there a solution to this yet? If not, then could someone recommend me a similar product to replace the one I have?

Hi,

This was a problem on some computers, the problem has been addressed in the later version of the software, have you tried to download the latest version of our software R5.16.2?

Let me know how you are getting on.

Kind regards
