Negative current values while voltage measurements are positive

[DAQuser]

Hi, I am using DAQ tool for power measurements of CPU power domain. I recorded the current and voltage samples while running the applications. What I observed that sometimes I am getting negative current values while voltage values are positive. Are this negative current values due to noise? Regards, D.verma

Hi, Voltage values are positive because it is dc voltage but could not figure out the negative current values which are coming some times. Is it possibility because of noise? Regards, D.verma

Please post a schematic of your setup.
