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:
and a few days later: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;4:14:00;1,5467e+006;1,5533e+006;
What do these values mean? E.g. how can I calculate the actual measured pH value from a number like 1,3829e+006?8-3-2009;12:14:00;-15592;4068,6;
8-3-2009;13:14:00;4068,6;1,6687e+006;

8-3-2009;15:14:00;4068,6;4068,6;
The display graphics button in the application shows this chart:
As you can see the data contains quite some spikes.. is that normal?
