CLEAR ALL STATUS REGISTERS
Clear Status Command
Clears all Event Registers, including the Status Byte, the Standard Event Status and the Error
Queue.
Command:
*CLS
[:]STATus[<channel>]:CLEar
SCPI Preset Status
Configures the status data structures to ensure that certain events are reported at a higher
level through the status-reporting mechanism. These events are summarized in the
mandatory structures, the Operation Status Register and Questionable Status Register.
The PRESet command affects only the enable registers and the transition filter registers of
the status data structures. PRESet does not clear any of the event registers or any item from
the error/event queue. The *CLS command is used to clear all event registers and queues in
the device status-reporting mechanism.
For the device-dependent status data structures, the PRESet command sets the enable register
to all 1s and the transition filter register to report only positive transitions. For the SCPI
mandatory status data structures, the PRESet command sets the transition filter registers to
recognize only positive transitions and sets the enable register to 0s. The following will not
be affected by this command: Service Request Enable Register, Parallel Poll Enable Register,
the memory register associated with the * SAV command, the power supply address, Output
Queue, and the power-on-status-clear flag setting.
