Cls (Clear Status Command) - HP 53131A/132A 225 MHz Programming Manual

Chapter 4 Command Reference
Introduction
*CLS
(Clear Status Command)
*CLS
Clears all event registers summarized in the status byte (Standard Event Status
Register, Operation Event Status Register, and Questionable Data Event Status
Register) and clears the Error Queue. The *CLS command will not clear data
memories or any other settings.
It also places the instrument in "Operation Complete Idle State" and "Operation
Complete Query Idle State" (IEEE 488.2). This results in the disabling of any
prior *OPC command.
If *CLS immediately follows a program message terminator, the output queue and
the MAV bit are cleared because "any" new program message after a program
message terminator clears the output queue.
This command will clear any displayed error message from the front panel.
