Hi, i am using msp430i2041 adc to measure resistance ranging from 1mohm to 1Kohm.. the problem that i am facing is that when i connect a power supply at the adc pins it shows correct measured voltage.. But if i connect a current source with resistance connected to it.. the voltage is equal to the resistance.. but this voltage is not correct.. If i connect my multi meter it shows correct values but if i connect the adc it adds extra voltage...
