6.24 Common Command Group
The commands in the common group are defined in the IEEE488.2-1992 and are independent of the instrument's
functions. There are no front panel keys that correspond to the commands in this group.
*CAL?(CALibrate)
Function Executes zero calibration (zero-level
compensation, same operation as pressing CAL
(SHIFT+SINGLE)) and queries the result.
*CAL?
Syntax
*CAL? -> 0
Example
Description If the calibration terminates normally, 0 is
returned. If an error is detected, 1 is returned.
*CLS(CLear Status)
Function Clears the standard event register, extended
event register, and error queue.
*CLS
Syntax
*CLS
Example
Description • If the *CLS command is located immediately
after the program message terminator, the
output queue is also cleared.
• For details on the register and queue, see
chapter 7.
*ESE
(standard Event Status Enable
register)
Function Sets the standard event enable register or
queries the current setting.
*ESE {<NRf>}
Syntax
*ESE?
<NRf> = 0 to 255
*ESE 251
Example
*ESE? -> 251
Description • Specify the value as a sum of decimal values
of each bit.
• For example, specifying "*ESE 251" will cause
the standard enable register to be set to
"11111011." In this case, bit 2 of the standard
event register is disabled which means that bit
5 (ESB) of the status byte register is not set to 1,
even if a "query error" occurs.
• The default value is " *ESE 0 " (all bits
disabled).
• A query using *ESE? will not clear the contents
of the standard event enable register.
• For details on the standard event enable
register, see page 7-5.
6-114
*ESR?(standard Event Status Register)
Function Queries the standard event register and clears
the register.
*ESR?
Syntax
*ESR? -> 32
Example
Description • A sum of decimal values of each bit is returned.
• You can check what type of events occurred
when an SRQ is generated.
• For example, if a value of "32" is returned, this
indicates that the standard event register is set
to "00100000." In this case, you can see that
the SRQ occurred due to a "command syntax
error."
• A query using *ESR? will clear the contents of
the standard event register.
• For details on the standard event register, see
page 7-5.
*IDN?(IDeNtify)
Function Queries the instrument model.
*IDN?
Syntax
*IDN? ->
Example
YOKOGAWA,WT3004E-2A0-30A4,0,F6.01
Description • The information is returned in the following
form: <Manufacturer>,<Model>,<Serial
No.>,<Firmware version>
• <Model> is in the format "model (7 digits)-2 A
input element configuration (3 digits)-30 A input
element configuration (4 digits)" For details on
the model code and input element structure,
see "Checking the Contents of the Package" in
the user's manual, IM WT3001E-01EN.
• In actuality, <Serial No.> is not returned
(always 0).
