poll. The RQS bit is not affected by the condition that caused the 
SRQ. The serial poll command transfers the value of the Status 
Byte register to a variable.
*CLS 
Syntax     *CLS
Definition     The *CLS command clears the following:
• Error queue
• Standard event status register (ESR)
• Status byte register (STB)
After the *CLS command the instrument is left 
waiting for the next command. The instrument 
setting is unaltered by the command, though 
*OPC/*OPC? actions are canceled.
If the *CLS command occurs directly after a 
program message terminator, the output queue 
and MAV, bit 4, in the status byte register are 
cleared, and if condition bits 2-0 of the status 
byte register are zero, MSS, bit 6 of the status 
byte register is also zero.
Example     OUTPUT 728;"*CLS"

Syntax     *ESE <wsp><value>
0

status register (ESR).
