Hi dear all.
I am trying to measure the voltage across the low value resistance which is 110ohm and 16ohm in NI 6251,i am applying 5vdc through a known 50Ko resistance to drop 0.1ma current to measure the resistacne value,when i am measuring i am getting some 4 to 6 ohm fluctuvation in measurements,so can any one tell how to solve this problem,because i need to measure the constant value,even i tried by giving +5vdc and gnd from daq pin to rathere than applying 5vdc from power supply,at that time also i got fluctuvation,so here i attached the snap which i measured in MAX for both...
Thanking You.
