Chapter 4 Command Reference
Common Commands
*CLS
(Clear Status Command)
*CLS
COMMAND
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 does not clear data memories or any other
COMMENTS
settings.
• *CLS 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, since any new program
message after a program-message terminator clears the output queue.
• This command clears any displayed error message from the front
panel.
• If the front panel is displaying any menu when *CLS is received, the
menu is abandoned (equivalent to pressing the Clear key).
