The SESR (Standard Event Status Register).
not prevent events from setting bits in the SESR. This facilitates
polling as a means of detecting these events, since the SESR
can be polled (read) using the *ESR? command, irrespective of
the bits set or not set in the Standard Event Status Enable
Register.

SCPI Status Byte

9.2.3
The SCPI Status Byte registers the status of the instrument, in one of seven bits
described in Table 9–3. Read the SCPI Status Byte status register by issuing either
the *STB? command or a serial poll. Clear the Status Byte status register by issuing
the *CLS command.
NOTE: Serial poll is applicable only to GPIB interface.
The Power Supply can be configured to request service from any of the communication
interfaces, by setting the appropriate bits in the Service Request Enable Register
(SRE), which has the same bit pattern as the status byte. Service Request Enable
Register (SRE) can be modified by issuing the *SRE <mask> command. Service
Request Enable Register (SRE) can be read by issuing *SRE? query command, See

0x01 Operation Complete
0x02 Request Control - not used
0x04 Query Error
0x08 Device Dependent Error
0x10 Execution Error (e.g., range error)
0x20 Command Error (e.g., syntax error)
0x40 User Request - not used
0x80 Power On
The SESER (Standard Event Status Enable Register). This
register is read using the *ESE? SCPI query command.
This register is written to using the *ESE <value> command.
A "1" in the appropriate bit location enables that
corresponding bit from the SESR to pass through to the
input of the OR gate to be included in the SESR summary
bit (bit 5) in the SCPI Status Byte.
