Measurement data format

[cspare]

I've enabled the logging of measurement data for the pH and temperature sensors. I can then read the stored data to my computer. In the dialog box I select Comma as decimal marker, Semicolon as Column separator and I check the 'with units' box. When I look at the file it generated I'm a bit confused about the numbers used -- I've got no idea how to interpret them.
The file contains this information:

Date;Time;pH-value 1[pH];Temperature 1[°C];
3-3-2009;22:14:00;1,3829e+006;1,4222e+006;
3-3-2009;23:14:00;1,4615e+006;1,4943e+006;
4-3-2009;0:14:00;1,5271e+006;1,5533e+006;
4-3-2009;1:14:00;1,5467e+006;1,5467e+006;
4-3-2009;2:14:00;1,5533e+006;1,5402e+006;
4-3-2009;3:14:00;1,5467e+006;1,5533e+006;
4-3-2009;4:14:00;1,5467e+006;1,5533e+006;

and a few days later:

8-3-2009;12:14:00;-15592;4068,6;
8-3-2009;13:14:00;4068,6;1,6687e+006;
8-3-2009;14:14:00;2,7804e+007;1,0237e+005;
8-3-2009;15:14:00;4068,6;4068,6;

What do these values mean? E.g. how can I calculate the actual measured pH value from a number like 1,3829e+006?

The display graphics button in the application shows this chart:

As you can see the data contains quite some spikes.. is that normal?

[Matthias]

These are no normal values.
You should see values like 24.6 for temp and 7.77 for pH.
Is there maybe a transmission problem?
Firmwareversion? Softwareversion? Connected via?

I got it working now, I updated my client software to version 4.0.5.0 (I had version 3.8 i think). The data export now shows correct values. thanks.

Hi, i tried using the measurement data to display graphics
but i could not see anything the graph came out but no indications and values.
how to go about doing it?

[Matthias]

did you enable the recording of the measurement values?

Menu "Measurement data"->"Vaules to save": set the check marks

[Devilsbar]

yes i did, let me try again. thanks

[Devilsbar]

seems unable to view it yet,
when i select graphic display i was promted to select a .txt file.
where do i get the .txt file thanks

[Matthias]

it is there where you saved your measurement data before

[Devilsbar]

it is in .par file,how do i open it.
from the ghl graphic display,i can only open .txt file.

[Matthias]

the par file is the file where you stored all settings of your ProfiLux, this is not the correct file

you have to save the measured values in a file, click "Read and Save" on the measurement page
