I am using PS6 and doing Save As always writes out a CSV file with the sample number (1 2 3 ... ) in the first column.
I need a CSV file with the computer time in it e.g. 10:30
Is there any way to make the program start up with the graph in Scroll mode and with a specific number of samples on the x axis? The only way I can see of doing that is to start it with defaults (probably Auto for x and Auto for y - seem to be random) and run some kind of script language which drives the user interface form to start it off, waits for say 100 samples to arrive (100 seconds - the ADC conversion on the PT-104 is 700ms so anything less than 1 sec doesn't do anything useful) and then flips the x axis from Auto to Scroll.
More basically I would like the whole program to start up configured and just start logging.
I have four PT-100 sensors connected. These are top grade, 0.05C accuracy. The PT-104 appears to have been calibrated to within 0.1C and two of them were close and the other two were close but the two pairs were 0.1C apart. So I calibrated them to be within 0.02C of each otherhttp://i.imgur.com/E5fJVQU.jpg
I used the Scaling function to add a little offset. That works great. But I am concerned that this tweak might get lost when the app is restarted, so I have a procedure whereby I always start it by opening a previous data file and then starting a new file. What exactly controls if these scaling values get saved?
The A-D converter is a little more noisy than I would have expected of a "24 bit" device taking 700ms (the noise seems to be about 10 LSBs so only about 20-21 bits of the 24 are meaningful) but really 0.02 degC of noise is OK for what I need. I have tried the filtering function but it results in a ~ 10 second delay before any
input change is noticed (at all) and then you get a very strange response which contains huge steps. It isn't the standard common FIR filter, or maybe it is an FIR filter but has an error in the implementation.
