The Channel EventStatus register describes the
captured
status. Depending on the status of the
channel the bits will be set but not reset. A reset has to be done by the user by writing an 1 to this
event bit. All Events can be cleared by :EVENT:CLEAR.

An event bit is permanently set if the corresponding status bit is 1 or is changing to 1. Different to the
status bit an event bit isn't automatically reset. A reset has to be done by the user by writing an 1 to
this event bit.
If one of the EventStatus Bits EVLIM, ECLIM, ETRIP, EEINH, EVBNDs, ECBNDs, EEMCY is set, it
prevents turning on the High Voltage again until the corresponding bit is cleared.
