ADC-20 voltage measurement problem?
ADC-20 voltage measurement problem?
Hello,
Why voltage measurement ADC-20 data logger is not working like it should? I measurement to voltage that is 24 volts and Uadc should be about 2.5 volts. Ra is the resistance value 866 ohms and Rb 100 ohms. Current measurement operates on all channels correctly, but what's wrong with the measurement of voltage? Perhaps the setting values or not, both can operate at the same time act?
Greetings

Hi,
What do you see in Picolog? Have you tried to use the voltmeter to see what voltage you get after it is attenuated?
Also try using a 10k and 1.1k
Kind regards
