6.2.2 Standard Event Status Register (ESR)
Read the Standard Event Status Register (ESR) by issuing the *ESR?
command. Reading this register or issuing a *CLS command will clear
the ESR. Use the *ESE (Standard Event Status Enable Register) to
enable corresponding ESR bits to be summarized in the summary bit of
the SCPI Status byte. To configure the Digital Interface Adapter (DIA) to
generate service requests based on the ESR, both the Standard Event
Status Enable Register and the Service Request Enable Register must
be programmed. See , and refer to Section 5 for further information.

Bit Hex Value Description
0 0x01 Operation Complete
1 0x02 Request Control - not used
2 0x04 Query Error
3 0x08 Device Dependent Error
4 0x10 Execution Error (e.g., range error)
5 0x20 Command Error (e.g., syntax error)
6 0x40 User Request - not used
7 0x80 Power On
6.2.3 Protection Condition and Protection Event Status
Register
These two registers have the same bit meanings, but they differ in
function.
Read the Protection Condition Register by issuing the
STAT:PROT:COND? command. This command gives the present status
condition of the power hardware, so the data is not latched. It is meant to be
used as a polling register.
Read the Protection Event Status Register by issuing the
STATus:PROTection:EVENt? command. Reading this register clears the
Protection Event Status Register. Or clear the Protection Event Status
Register by issuing a *CLS command or a *RST command. Bits in the
Protection Event Status Register will be set only when the corresponding
bit in the Protection Event Status Enable Register is set and the
corresponding event occurs. The status is then latched and will remain in
that state until it is read or cleared due to some command action. (Set the
Enable Register with the STATus:PROTection:ENABle command,
and query the Enable Register with the STATus:PROTection:ENABle?
query).
