I am using a Keithly power supply sourcing DC current. The devices I am trying to measure are becoming damaged, I believe due to some overshoot when the meter transitions from low to high current. What kind of circuit can I put in order to smooth out the transition from low to high?? High pass filter?? Typically I am trying to measure a device around 120, 125 ohms at 125mV. So typically I am sourcing around 1mA of current. Thanks for your help!!
