IEEE-488 Common commands usually control all instrument functions, such as
reset, status, and synchronization. All common commands consist of a
three-letter mnemonic, and are preceded by an asterisk, E.g:*RST *IDN? *SRE 8.
*CLS
This command clears the error queue and the bits of the following registers:
âš« Standard Event Register
âš« Questionable Event Register
âš« Status byte register
Syntax:
*CLS
Arguments:
None
*ESE
This command sets the bits in the Event Status Enable Register (ESER). The ESER
is an eight-bit register that determines which bits in the Standard Event Status
Register (SESR) will set the Event Summary Bit (ESB) in the Status Byte Register
(SBR).
