The commands in the common command group are independent of the instrument’s functions, and are specified
in IEEE 488.2-1987. There is no front panel key that corresponds to this group.

*CAL? (CALibrate)
Function Performs calibration and queries about the
result.
Syntax *CAL?
Example *CAL? -> 0
Description “0” will be returned if calibration is completed
properly, and “1” will be returned if an
abnormality has been detected during
calibration.
*CLS (CLear Status)
Function Clears the standard event register, extended
event register and error queue.
Syntax *CLS
Example *CLS
Description • The output queue will also be cleared if a
*CLS
command is appended after the
program message terminator.
• For details of the registers and queue, refer
to Chapter 6.
*ESE (standard Event Status Enable
register)
Function Sets the value for the standard event enable
register/queries about the current setting.
Syntax *ESE {<NRf>}
*ESE?
<NRf>=0 to 255
Example *ESE 251
*ESE? -> 251
Description • <NRf> is the sum of the bits expressed as a
decimal number.
• For example, if “*ESE 251” is set, the
standard event enable register will be set to
“11111011.” This means that bit 2 of the
standard event register is disabled so that bit
5 (ESB) of the status byte register will not be
set to “1,” even if an query error occurs.
• Default is “*ESE 0,” i.e. all bits are disabled.
• The standard event enable register will not
be cleared, even if an query is made using
“
*ESE? .”
• For details of the standard event enable
register, refer to page 6-3.
