I have an power suplly model Agilent E3631A.
When I adjust the voltage to 25V, the value is showed in display, but in my output is 20V. I measure the output with an external multimeter ( I uses any multimeter for the test, so the multimeter is ok).
When a I click in "Display Limit" Option, I can adjust the voltage correctly, shows in display 25V e and I measure 25V in multimeter.
Does anyone have any idea what the problem might be?
