Command syntax
Common
commands
Specific
commands
Keywords
#
The brackets ([ ]) are used to frame a keyword which is optional during
programming; i.e. the instrument will execute the command whether the
keyword is optional or not. Uppercase and lowercase are used to
differentiate the short form of the keyword (uppercase letters) and the long
form (whole word).
The instrument accepts the uppercase or lowercase letters without
distinction.
FUNC:SIN is equivalent to SOURCE:FUNCTION:SHAPE SINUSOID
Parameters The parameters, if any, are separated from the keyword by a space (' '). A
command can accept parameters of a defined type, a literal expression or a
combination of both.
The defined-type parameters are marked by the characters < >.
The brackets ([ ]) mean that the parameters are optional.
The vertical bar ( | ) may be read as an "or", it is used to separate the
various possible parameters.
Separators The separator ' : ' descends in the next directory or returns under the root, if
preceded by a ' ; '.
The separator ' ; ' separates two commands in the same directory or marks
the end of a directory command, enabling a return to the root level by
adding the separator ' ; '.
The separator ' ' (space) separates the keyword from the following
parameter.
Terminators <T> used as a general term designating a terminator.
T is the character CR (ASCII code 13 or 0x0D) or the CR character followed
by the LF character (ASCII code 10 or 0x0D)
A command line must not exceed 80 characters; it is ended by a terminator.

Convention
Tree structure The command tree diagram includes all the commands specific to the
instrument.
Common commands (standard IEEE 488.2) are listed separately, since they
do not affect the position of the syntax analyzer in the tree.
When the terminator <NL> is sent to the instrument, the analyzer is
positioned at root level.
When the analyzer is in a directory, both separators ' ;: ' are necessary to
return to the root.

TEMPerature:TRANsducer[?] (Command/Query)
The command TEMP:TRAN <PT100|PT1000|TCJ|TCK> selects the
type of transducer used for the temperature measurement.
To the question TEMP:TRAN?, the instrument returns the type of
transducer used for the temperature measurement.

Commands SYSTem
BEEPer:Status[?] (Command/Query)
The command SYST:BEEP:STAT <0|1|OFF|ON>, activate or de-
activate the beeper of the instrument.
The values are 0 or OFF to de-activate and 1 or ON to activate.
To the question SYST:BEEP:STAT?, the instrument returns the
activation status of the beeper.
COMMunicate:SERial
[:RECeive]:BAUD[?] (Command/Query)
The command SYST:COMM:SER:BAUD <9600|19200|38400>,
selects the communication speed of the serial link device.
To the question SYST:COMM:SER:BAUD?, the instrument returns
the communication speed of the serial link device.
DATE[?] (Command/Query)
The command SYST:DATE <year,month,day>, sets the date.
To the question SYST:DATE?, the instrument returns the date.
The parameter <year> is an integer numeric value from 1 to 36.
The parameter <month> is an integer numeric value from 1 to 12.
The parameter <year> is an integer numeric value from 1 to 31.

ERRor[:NEXT]?
(Query)
To the SYST:ERR? question, the instrument returns the error number positioned
at the top of the queue. The queue may have up to 10 numbers and it is
managed according to the principle of first in, first out.
As the SYST:ERR? questions progress,the multimeter returns the error
numbers in the order of their arrival, until the queue is empty.
Any additional SYST:ERR? question will cause a negative response:
"0,No error".
If the queue is full, the box located at the top of the queue takes the –350 value
(queue saturated).
The queue is emptied :
- on powering on
- on receipt of a *CLS
-on reading the last error
Response format : <error,message><T>
with: error = integer negative or null.
message = corresponding error message
Error list * Command errors : (-199 to –100)
They indicate that a syntax error has been detected by the syntax analyzer and
caused event register bit 5, called CME, CoMmand Error, to be set to 1
-101 : Invalid character
-103 : Invalid separator
-104 : Data type error
-108 : Parameter not allowed
-109 : Missing parameter
-111 : Header separator error
-112 : Program mnemonic too long
-113 : Undefined header
-114 : Header suffix out of range
-121 : Invalid character in number
-128 : Numeric data not allowed
-141 : Invalid character data
-148 : Character data not allowed
-151 : Invalid string data
-154 : String data too long
* Execution error : (-299 to –200)
They indicate that an error has been detected at the moment of command
execution, and causes event register bit 4, called EXE, Execution Error, to be set
to 1.
-200 : Execution error
-203 : Command protected
-221 : Settings conflict
-222 : Data out of range
* Instrument specific errors : (-399 to –300)
They indicate that an abnormal error has been detected during execution of a
task, and causes event registry bit 3, called DDE, Device Dependent Error
to be set to 1.
-300 : Device specific error
-350 : Queue overflow
-360 : Communication error
* Query errors : (-499 to –400)
They indicate that an anomaly in the information exchange protocol has occurred
and causes event register bit 2, called QYE, QuerY Error, to be set to 1.
-400 : Query error
