Chapter 1 Introduction

This chapter provides the guidance for user to use a RIGOL DM3000 series digital
multimeter for remote control programming correctly, and to achieve a long-distance
measuring operation.

This chapter includes:

 Programming Introduction

 Symbol Instruction

 Parameter Types

 Commands Introduction

Programming Introduction

This part intrduces the basic programming operations.These programming commands
provide the methods for remote control to a multimeter.

The Basic operations that you can do with a computer and a multimeter include:

 Setup a multimeter.
 Measure.
 Receive data (equipment working condition or measurement results) from a

multimeter.

A computer can communicate with a multimeter by sending and receiving messages
over an I/O port, such as USB, GPIB port or a RS-232 port. The commands appear as
ASCII strings embedded inside the output statements of a “host” language available
on your computer, so users can control and do the secondary development. Please
refer to the user guide about the connection methods of communication interface.

Symbol Instruction

1. Colon :

Commands usually begin with a colon (:). A colon (:) is used to separate a command
keyword from a lower-level keyword. It shows the operation that a multimeter will
implement.

2. Blank Space □

A Blank space is used to separate commands from the program data. If your
command does not need any program data, the blank space is not needed.

3. Interrogation ?

A query is formed by adding an interrogation (?) to the end of the commands. The
query commands usually include different data, and both of them usually divided by a
space □. But some commands don’t include data.

4. Braces { }

When several elements separated by a vertical line (|) are enclosed by braces, { },
only one element may be selected. For example, {ON | OFF} indicates that only ON or
OFF may be selected, not both.

5. Triangle Brackets < >

A item enclosed in < > should be replaced by a numerical value or character string.

Parameter Types

1. Consecutive Integer Parameter

The parameters can be any integer only in effective range. Note that do not set the
parameters for decimal format, or else abnormal. For example, setting screen
brightness command ": system: display: bright", the parameter range is from 0 to

255.

2. Consecutive Real Number Parameter

In effective value range, the parameters can be random value according to precision
(usually the default precision takes six effective digits behind decimal point). For
example, setting NULL offset command ": calculate: NULL: offset", the parameters
meet the range of the real number Table 2- 12 indicated.

3. Discrete Parameters

The parameters can only be the cited value. For example, setting AC voltage measure
range command ": measure: voltage: AC", the parameter can only be 0, 1, 2 or 3,
but not other values.

4. Boolean Parameters

The parameters can only be ON or OFF. For example, setting beeper state command

“:system:beeper:state”, the parameter can only be ON or OFF.

5. ASCII Character string

The parameter should be composed of ASCII character string. For example, setting
date command ":system:clock:date”, the parameter can be a character string of
date format.

packet every time, including 512 sampling data and occuping the storage space for 2K.
The value is the serial number of the data packet, the range is 1 ~ 4096. Every datalog
starts storaging from the first packet. The sencondary developmant of the PC
programm needs RIGOL drive programm and dynamic link library to change the
obtained 32 digits binary data into floating-point-type data, and calculates the
numbers of the effective data and pick up. Please refer to RIGOL Demo programm
about the use methods of the programm.
