Question asked by akhil on May 23, 2020

i am using this power supply for current calibration. My test device connected to my PC  using USB.Power supply connected to the test device for current supply and power supply connected to the same PC using USB cable.During 0v setup no current draw. When I increase the voltage, the current automatically increasing to 0.11 A. During this time I removed the Positive terminal of the power supply but the current is the same. Current drawing through the -ve terminal. Earthing is proper, measured 0.8V across the earth to neutral.
