The Channel Event Status contains the captured status. An event bit is set if the corresponding Channel 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.
All channel events can be cleared by the
command. With the command *CLS all module and channel event
registers are cleared at once.
Some event bits also perform a blocking function, which means if this Bit and it’s corresponding event mask bit is set, then:
•
The voltage set value can not be increased while the high voltage is on
•
After the high voltage is turned off, it cannot be turned on again
After either the event bit or the corresponding mask is cleared, the blocking is disabled again.
