If the negative current limit query returns a value that equals 10% of the rated current of the power
supply, the power dissipator is not recognized by the power supply. Turn the power supply off, make
sure that the power dissipator is properly connected, and turn the power supply on again.
For 1 kW models, if the negative current limit query returns a value that equals 100% of the rated
current of the power supply, the power dissipator is connected and recognized.
For 2 kW models, if the negative current limit query returns a value that equals 100% of rated current
of the power supply, both power dissipators are connected and recognized. If the value equals 50% of
the rated current, only one power dissipator is connected and recognized.
