Clearing registers

Registers in the status model can be cleared using commands or by instrument actions. When a

The event log and all registers are cleared when instrument power is cycled.
When you read a bit from the Operation Event, Questionable Event, or Standard Event Status
Register, the entire 16-bit or 8-bit register value is returned. The event register is cleared or set to 0.
