I am using INA3221 3 channel shunt voltage and current measuring module to measure the current through a 12V DC motor. I first tested with some resistors as the load and got the correct readings. (around 250mA ). However when i reduce the load resistor (around 500mA) , INA3221 started to give negative values and also magnitude of these values reduces when i decrease the load resistor furthermore. It happens in all 3 channels. I saw another post with the same issue but there wasn't any reply to that. What could be the reason for this ?
Thanks in Advance!!
