I have a question about my E3646A output2 indicates .
At 21 degrees,this power suppliy will indicates 0.01V & 0.0001A with no load if select OUTPUT 2 and enable OUTPUT ON.
If put it in a cold room at 15 degrees, OUTPUT 2 indicates 0.00V & 0.0000A. I have checked the actual output,it seems match accuracy in spec.
But OUTPUT 1 will always indicate 0.00V & 0.0000A under vary temperature.

Does this power supply work fine with 0.01V & 0.0001A ,how to explain the indicates? Thank a lot!
