3.5.1 Standard event status register (ESR)
The ESR can be read directly with the command "*ESR?". Reading the ESR clears it
at the same time. The content of the ESR can not be set.
The bits are active high and have the following meaning:
Power on
This bit indicates an off to on transition in the power supply. So it is high after
switching on the device for the first time.
User request (not used here)
A local control has been activated.
