N5771A problems with full load

Hello there!

My power supply works fine until I forced it to the maximum levels... When I increase the voltage near to 280V and current is 4.9 A the power supply works at least 30 seconds and the voltage falls down until 250V, current to 3.5A, you can decrease but not increase the levels.
In addition, I check the current with a DMM and there´s a difference between my DMM and the front panel display.

Do you think this is a calibration problem?

best regards
