Example SCPI Commands
To request the current pressure reading, all of the following commands are equivalent:
To zero the unit via the remote interface use the following sequence:
SCPI Status Registers
Three types of status registers are available: Condition, Event, and Enable.
Condition registers always show the current status of the instrument. Bits may turn on
and back off between reads. The status read is the status of instrument at the moment of
the read. Condition registers include:
Event registers do not show the current state but flag the bits in the condition registers
that have changed since the last time the event register was read. When an event register
is read it is reset to zero.
Enable registers are set by the user to create summary bits. If the user sets a bit in the
enable register, when the instrument sets the corresponding bit in the event register a
summary bit in the Status Byte Register is set.
The Service Request Enable Register (*SRE) is used to generate service requests on the
IEEE-488 bus. If a user sets a bit in this register, when the instruments sets the
corresponding bit in the Status Byte Register (*STB) a service request is generated.

Bit 7
Operation status summary. Set when an event enabled in OPER:ENABLE
occurs.
Bit 6
Service request. Set when an event enabled in SRE occurs. (This bit is not
used in SRE.)
Bit 5
EBS - Event status bit. Set when an event enabled in ESE occurs.
Bit 4
MAV - Message available. Set when a response is ready to be sent.
