Common Commands
*CLS
This command causes the following actions (see chapter 5 for the descriptions of all registers):
K Clears the Standard Event Status, Operation Status Event, and Questionable Status Event registers
K Clears the Status Byte and the Error Queue
K If *CLS immediately follows a program message terminator (<NL>), then the output queue and the
MAV bit are also cleared.
Command Syntax *CLS
Parameters None
*ESE
This command programs the Standard Event Status Enable register bits. The programming determines
which events of the Standard Event Status Event register (see *ESR?) are allowed to set the ESB (Event
Summary Bit) of the Status Byte register. A "1" in the bit position enables the corresponding event. All
of the enabled events of the Standard Event Status Event Register are logically ORed to cause the Event
Summary Bit (ESB) of the Status Byte Register to be set. The query reads the Standard Event The query
reads the Standard Event Status Enable register.
