Query Messages
In this publication, items relevant only to the DM7275-01, DM7275-02, DM7275-03, DM7276-01, DM7276-02, and
DM7276-03 are indicated as “the instrument.”
If the communication monitoring function is used at the time of program creation, commands and responses will be
conveniently displayed on the measurement screen. For information on the communication monitoring function, see
the instruction manual of the instruments.
Various messages are supported for controlling the instrument through the interfaces.
Messages can be either program messages, sent from the controller such as PC to the instrument, or response
messages, sent from the instrument to the controller.
Response Messages
Message types are further categorized as follows.
When issuing commands that contain data, make sure that the data is provided in the specified format.
Message Format
Program Messages
Program messages can be either Command Messages or Query Messages.
(1) Command Messages
Instructions to control the instrument, such as to change settings or reset
Example: (instruction to set the measurement range)
:VOLTAGE:DC:RANGE 100
Header portion
Space Data portion
(2) Query Messages
Requests for responses relating to results of operation or
measurement, or the state of instrument settings
Example: (request for the current measurement range)
:VOLTAGE:DC:RANGE?
Header portion
See: “Headers (p.2)”, “Separators (p.3)”, “Data Formats (p.4)”

Response Messages
*
When a query message is received, its syntax is checked and a response message is generated.
If an error occurs when a query message is received, no response message is generated for that query.
Command Syntax
Command names are chosen to mnemonically represent their function, and can be abbreviated. The full
command name is called the “long form”, and the abbreviated name is called the “short form”.
The command references in this manual indicate the short form in upper-case letters, extended to the long form in
lower case letters, although the commands are not case-sensitive in actual usage.
FETCH?
FETC?
FET?
Response messages generated by the instrument are in long form and in upper case letters.
OK (long form)
OK (short form)
Error
Headers
Headers must always be prefixed to program messages.
(1) Command Program Headers
There are three types of commands: Simple, Compound and Standard.
• Headers for Simple Commands
This header type is a sequence of letters and digits
:ABORt
• Headers for Compound Commands
These headers consist of multiple simple command type headers separated by colons “:”
:VOLTage:DC:RANGe
• Headers for Standard Commands
This header type begins with an asterisk “*”, indicating that it is a standard command defined by IEEE 488.2.
RST
(2) Query Program Header
These commands are used to interrogate the instrument about the results of operations, measured values and
the current states of instrument settings.
As shown by the following examples, a query is formed by appending a question mark “?” after a program
header.
:FETCh?
VOLTage:DC:RANGe?
Characters within square brackets [ ] may be omitted.
[:SENSe:]VOLTage:DC:RANGe
Either form is valid.
:SENSe:VOLTage:DC:RANGe
VOLTage:DC:RANGe

Message Terminators
This instrument recognizes the following message terminators (delimiters).
[RS-232C/USB/LAN]
• CR
• CR+LF
[GP-IB]
• LF
• CR+LF
• EOI
• LF with EOI
Depending on the instrument’s interface settings, the following can be selected as the terminator for response
messages.
For information on settings, see “Delimiter Setting” (p.58).
[RS-232C/USB/LAN]
• CR+LF
[GP-IB]
• LF with EOI (default setting)
• CR+LF with EOI
Separators
(1) Message Unit Separator
Multiple messages can be written in one line by separating them with semicolons “;”.
:VOLTAGE:DC:RANGE 10;∗IDN?
• When messages are combined in this way and if one command contains an error, all subsequent messages up
to the next terminator will be ignored.
(2) Header Separator
In a message consisting of both a header and data, the header is separated from the data by a space “ ” (ASCII
code 20H).
:VOLTAGE:DC:RANGE 10
(3) Data Separator
In a message containing multiple data items, commas are required to separate the data items from one another.
:SYSTEM:DATE 15,1,1

Ω
@
°C
$
Data Formats
The instrument uses character data, decimal numeric data and character string data depending on the command.
(1) Character Data
Character data always begins with an alphabetic character, and subsequent characters may be either
alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument
are only upper case. When the command data portion contains <1/0/ON/OFF>, the operation will be similar to
when 0 is OFF and 1 is ON.
:VOLTAGE:DC:RANGE:AUTO OFF
(2) Decimal Numeric Data
Three formats are used for numeric data, identified as NR1, NR2, and NR3. Numeric values may be signed or
unsigned. Unsigned numeric values are handled as positive values. Values exceeding the precision handled by
the instrument are rounded to the nearest valid digit.
• NR1 Integer data (e.g.: +12, -23, 34)
• NR2 Fixed-point data (e.g.: +1.23, -23.45, 3.456)
• NR3 Floating-point exponential representation data (e.g.: +1.0E-2, -2.3E+4)
The term “NRf format” includes all three of the above numeric decimal formats.
The instrument accepts NRf format data. The format of response data is specified for each command, and the
data is sent in that format.
:STATus:OPERation:ENABle 49
:FETCH?
+102.20192E-03
(3) Character string data
• Character string data is enclosed by quotation marks.
• This type of data consists of 8-bit ASCII characters
• Characters that cannot be handled by the instrument cause an error.
• The following two characters are different for the instrument setting and communications setting. (Scaling Unit
and Label Display Function)
Instrument setting Communication setting
*Only Scaling Unit and
with remote command.
• As for quotation marks, the sender form the instrument uses double quotes (”) only, while the receiver receives
both double quotes and single quotes (’).
Label Display Function are supported. About other functions, Ω and °C cannot be set
:SYSTem:LABel “LABEL_01”
[GP-IB]
The instrument does not fully support IEEE 488.2. As much as possible, please use the data formats shown in
the Reference section.
5
Compound Command Header Omission
When several commands having a common header are combined to form a compound command
(e.g., :CALCulate:SCALe:PARameterA and :CALCulate:SCALe:PARameterB) if they are written together in
sequence, the common portion (here, :CALCulate:SCALe) can be omitted after its initial occurrence.
This common portion is called the “current path” (analogous to the path concept in computer file storage), and until it
is cleared, the interpretation of subsequent commands presumes that they share the same common portion.
This usage of the current path is shown in the following example:
Full expression
:CALCulate:SCALe:PARameterA 1.0; :CALCulate:SCALe:PARameterB 0.0
Compacted expression
:CALCulate:SCALe:PARameterA 1.0; PARameterB 0.0
This portion becomes the current path, and can be omitted from the messages immediately following.
The current path is cleared when the power is turned on, when reset by key input, by a colon “:” at the start of a
command, and when a message terminator is detected.
Standard command messages can be executed regardless of the current path. They have no effect upon the
current path.
A colon “:” is not required at the start of the header of a Simple or Compound command. However, to avoid
confusion with abbreviated forms and operating mistakes, we recommend always placing a colon at the start of a
header.
Output Queue and Input Buffer
Output Queue
Response messages are stored in the output queue until read by the controller. The output queue is also cleared
in the following circumstances:
• Power on
• Device clear [GP-IB]
• Query Error
Input Buffer
The input buffer capacity of the instrument is 256 bytes.
If 256 bytes are allowed to accumulate in this buffer so that it becomes full, the USB and GP-IB interface bus enters
the waiting state until space is cleared in the buffer.
The RS-232C interface may not process data beyond 256 bytes.
Note: Ensure that the no command ever exceeds 256 bytes.

Status Byte Register (STB)
During serial polling, the contents of the 8-bit Status Byte Register are sent from the instrument to the controller.
When any Status Byte Register bit enabled by the Service Request Enable Register has switched from 0 to 1, the
MSS bit becomes 1. Consequently, the SRQ bit is set to 1, and a service request is dispatched.
The SRQ bit is always synchronous with service requests, and is read and simultaneously cleared during serial
polling. Although the MSS bit is only read by an *STB? query, it is not cleared until a clear event is initiated by the
*CLS command.

Command Execution Time
Command execution time indicates the time for analyzing and processing long form commands.
However, the command execution time for commands with data is the time described according to the data format
specified in the <data portion>.
• Display delays may occur depending on the frequency of communication processes and process contents.
• All commands except *TRG and :INIT are processed sequentially.
• In communications with the controller, time must be added for data transmission. USB and GP-IB transfer time depends
on the controller.
The RS-232C transfer time, with start bit 1, data length 8, no parity, and stop bit 1, has a total of 10-bit. When the transfer
speed (baud rate) setting is N bps, the general result will be as follows:
Transfer time T [1 character/sec] = Baud rate N [bps]/10 [bits]
Since a measurement value is 17 characters, a 1 data transfer time will be 17/T.
(Example) For 9600 bps, 17/(9600/10) = Approx. 17 ms
• Wait until measurements stabilize after a change before using a setting command.
