Warning: Identifies conditions or practices that could result in injury or loss of life.

CAUTION

Caution: Identifies conditions or practices that could result in damage to the ASR-3000 or to other properties.

SAFETY INSTRUCTIONS

This chapter contains important safety instructions that you must follow during operation and storage. Read the following before any operation to ensure your safety and to keep the instrument in the best possible condition.

Safety Symbols

These safety symbols may appear in this manual or on the instrument.

SAFETY INSTRUCTIONS

Do not dispose electronic equipment as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased.

General Guideline

CAUTION

 Do not place any heavy object on the ASR-3000.  Avoid severe impact or rough handling that

leads to damaging the ASR-3000.

 Do not discharge static electricity to the ASR-

3000.

 Use only mating connectors, not bare wires, for

the terminals.

 Do not block the cooling fan opening.  Do not disassemble the ASR-3000 unless you are

qualified.

 If the equipment is used in a manner not

specified by the manufacturer, the protection provided by the equipment may be impaired.

Safety Guidelines

ASR-3000 Programming Manual

Power Supply

WARNING

 AC Input voltage range:

200 ~ 240 Vac

 Frequency: 47 ~ 63 Hz  To avoid electrical shock connect the protective

grounding conductor of the AC power cord to an earth ground.

 The power switch that is included in the

instrument is not considered a disconnecting device.

 The permanently connected power input is used

as the disconnecting device and shall remain readily operable.

a. A switch or circuit-breaker must be included

in the installation

b. It must be suitably located and easily reached c. It must be marked as the disconnecting

device for the equipment.

d. It shall be located near the equipment

 Do not position the equipment so that it is

difficult to operate the disconnecting device.

 Ask for professional technician for installation.  It requires 200Vac input condition and the

maximum input current [15A (ASR-3200), 22.5A (ASR-3300), 30A (ASR-3400)], which conforms to cord diameter by local regulations.

 Breaker, of which the specification is required to

larger than 20A (ASR-3200), 30A (ASR-3300), 40A (ASR-3400) individually, should be in the near proximity of unit.

SAFETY INSTRUCTIONS

Cleaning the ASR3000

 Disconnect the circuit-breaker or permanently

connected power input before cleaning.

 Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

 Do not use chemicals containing harsh material

such as benzene, toluene, xylene, and acetone.

Operation Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Relative Humidity: 20%~ 80%, no condensation  Altitude: < 2000m  Temperature: 0°C to 40°C

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees and their requirements as follows. The ASR-3000 falls under degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Storage environment

 Location: Indoor  Temperature: -10°C to 70°C

 Relative Humidity: ≤90%, no condensation

Disposal

Do not dispose this instrument as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Please make sure discarded electrical waste is properly recycled to reduce environmental impact.

Command Structure

SCPI commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node. Each keyword in a SCPI command represents each node in the command tree. Each keyword (node) of a SCPI command is separated by a colon (:).

For example, the diagram below shows an SCPI sub-structure and a command example.

Command types

There are a number of different instrument commands and queries. A command sends instructions or data to the unit and a query receives data or status information from the unit.

Command types

Simple

A single command with/without a parameter

Example

*IDN?

Command Syntax

ASR-3000 Programming Manual

Query

A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned.

Example

meas:curr?

Compound

Two or more commands on the same command line. Compound commands are separated with either a semicolon (;) or a semi-colon and a colon (;:).

A semi-colon is used to join two related commands, with the caveat that the last command must begin at the last node of the first command.

Example

meas:volt?;curr?

A semi-colon and colon are used to combine two commands from different nodes.

Example

meas:volt?;:sour:volt?

Note (Further explanation)

A semi-colon(;) is used to connect two commands. A colon(:) at the start of a command indicates that the command starts from the root node. The first command can ignore that first colon. Any commands after the first command (for compound commands) that do not begin with a colon, must begin at the last node of the first command.

REMOTE CONTROL

Command Forms

Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case.

The commands can be written in capitals or lower-case, just so long as the short or long forms are complete. An incomplete command will not be recognized.

Below are examples of correctly written commands.

Long form

:SYSTem:ERRor? :SYSTEM:ERROR? :system:error?

Short form

SYST:ERR? syst:err?

Square Brackets

Commands that contain square brackets indicate that the contents are optional. The function of the command is the same with or without the square bracketed items, as shown below.

For example the query “:OUTPut[:STATe]?” has two valid forms, “:OUTPut:STATe?” and “:OUTPut?”.
