EGISTERS
These two registers have the same bit meanings, but they differ in function.
• To read the Protection Condition, use the STAT:PROT:COND?
command. This command gives the present status condition of the
power hardware, so the data is not latched. It is a polling register.
• To read the Protection Event Status, use the
STATus:PROTection:EVENt? command. To clear the Protection Event
Status Register, either read this register with the *RST command, or
issue the *CLS command.
• To set bits in the Protection Event Status Register, you must first set the
corresponding bit in the Protection Event Status Enable Register and
the corresponding event must occur.
• To set the Enable Register, issue the STATus:PROTection:ENABle
command. The status is then latched and will remain in that
state until it is read or cleared due to some command action. Then use
the STATus:PROTection:ENABle? query to read the Enable Register.
