Chapter2 Status register
You can get the current status of the power supply by reading the status
registers. The power supply records the different status of the instrument
through the four status register group. The four status register groups are:
Questionable Status Register, Operation Status Register, Standard Event
Register and Status Byte Register. Status Byte Register records the
information of the other status register.
The following table describes the status signals.
