Re: Help to users going from PicoLog5 to PicoLog6?

One more thing:
- I miss the Sampling Number being shown during measurement. This is a good way to orient oneself, for example if one wants to make notes of things happening during a measurement, it is easy to just note "s14328", instead of having to write down the time "2 days 14 h 23 m".

Re: Help to users going from PicoLog5 to PicoLog6?

Thanks for the link. It is well described how to connect loggers and start measurements, but I have problems with exporting and this is not described in any detail. Here are the the questions&comments I have: - After stopping a logging and saving the data, the filename that I gave when saving (as .p...

Help to users going from PicoLog5 to PicoLog6?

I have been using PicoLog with different PicoTech products for many years. Now I have somewhat reluctantly installed PicoLog6 on one of my computers, and my first impression is that some things are easy (setting up a measurement for example), but some things are not trivial (at least not for me), fo...

picolog 6 file format

Since many years I have maintained a MATLAB-program that imports (the old) PLW-files into the MATLAB workspace. Now, I want to upgrade this program so that it also works with picolog 6 files. Is there information available on the structure of the .picolog files?

conversion and sampling time

I use ADC-24 and I am have questions about conversion and sampling time: - Is there a limit on how many channels that can be measured with a certain combination of conversion and sampling time? So that, e.g., 5 channels with 660 ms conversion time and 5 s sampling rate is ok, but using 10 channels w...

Dear Guest. Thanks. However, I had to make some minor changes to lines 118-123 to make it run: t = zeros(1,param.no_of_samples); U = zeros(param.no_of_parameters,param.no_of_samples); for p=1:param.no_of_samples %here the samples are read t(p)=fread(fid,1,'uint')'; %time U(:,p)=fread(fid,param.no_of...

Now we have got the problem on a third computer also...and some new facts about it. It seems to be connected to the number of data logged. Previously we have seen the problem in the morning after having started logging the day before with 5 s interval. Changing to 1 s interval made the graphics cras...

Here is my program PLW2ML.m that converts PLW-files to MATLAB variables. On lines 59-69 you can see the differences I noted between the different versions 1, 2 and 3. Note that the param.PLS, which contains information about the run (for example the names given to the channels) had an initial part t...

Some time ago I wrote a MATLAB-program to read PLW-files directly into MATLAB. I remember that the manual did not give the whole truth, but also that (if I remember correctly) different versions (I found three) were slightly different. So if you want a program that works for all PLW-files you need t...

No, the file size is not the problem. I get this problem on two of my Pico-loggers (I have many more running without any problems) and the diagram goes strange after about one day collecting 8 channels @ 5 s (not much) every time I use these computers. I regularly collect for at least a week with th...

Same problem with diagrams as Malte J?

I seem to have the same problems as Malte Johansson described 31 January 2006 ("Diagram not correct after weekend"). I run at least 20 PLW applications in my lab (TC-08 serial, TC-08 USB and ADC-16) and some months ago the PLW running one of the TC-08:s lost the ability to show graphics correctly af...
