Specifying the Source/Load Function
You have the option to use the E36731A either as a standalone power supply or electronic load.
When switching between the instrument function, the output is turned off and the Source/Load Settings revert
to their Power-on or RST values.
When switching to Eload mode, there may be a few milivolts residual voltage briefly maintained at the load.
This is due to output capacitor dielectric absorption effect.
