Legend:
1) Difficult measurement lead to uncertain results, software was not
appropriate at that time.
2) Additional capacitors can be switched in for higher integration time
(10ms .... 3sec). Processor now 10bit ADC based on ATmega16, V1.6
3) if (during download) the file should be saved as *.zip then just rename it to
*.jar Prior to that you need to install Java Runtime system.
