Safety precaut ions

The following safety precautio ns should be obser v ed befor e usin g this product and any associated instrumentation . Alt ho ugh some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired. The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service personnel may perform installation and service procedures.

Keithley Instruments products are designed for use with electrical signals that are measurement, control, and data I/O connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high transient overvoltages. M easurement Category II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley Instruments measuring instruments may be connected to mains. These instruments will be marked as categor y II or higher.

Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains. Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test

fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 V, no conductive part of the circ uit may be ex posed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.

For safety, instruments and accessories must be used in accordance with the operating instructions. If the instruments or accessories are used in a manner not specified in the operating instructions, the protection provided by the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories. Maximum signal levels are defined in the specifications and operating information and shown on the instrument panels, test fixture panels, and switching cards.

When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard. Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety ground)

connections. If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use

of a lid interlock.

If a screw is present, connect it to protective earth (safety ground) using the wire recommended in the user documentation.

The

symbol on an instrument means caution, risk of danger. The user must refer to the operating instructions located in the

user documentation in all cases where the symbol is mark ed on the instr u ment .

The symbol on an instrument means caution, risk of electric shock. Use standard safety precautions to avoid personal contact with these voltages.

The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.

The

If this

symbol indicates a connection terminal to the equipment frame.

symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be

properly disposed of according to federal, state, and local laws. The WARNING heading in the user documentation explains dangers that might result in personal injury or death. Always read

the associated information very carefully before performing the indicated procedure. The CAUTION heading in the user documentation explains h az ards that coul d dama ge the instrument. Such damage may

invalidate the warranty. Instrumentation and accessories shall not be connected to humans. Before performing any maintenance, disconnect the line cord and all test cables. To maintain protection from electric shock and fire, replacement components in mains circuits — inc lud ing t he pow er

transformer, test leads, and input jacks — must be purchased from Keithley Instruments. Standard fuses with applicable national safety approvals may be used if the rating and type are the same. The detachable mains power cord provided with the instrument may only be replaced with a similarly rated power cord. Other components that are not safety-related may be purchased from other suppliers as long as they are equivalent to the original component (note that selected parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

Unless otherwise noted in product-specific literature , Keithle y Instru ment s instr ume nts are desi gne d to operate indoors only, in the following environment: Altitude at or below 2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution degree 1 or 2.

To clean an instrument, use a damp cloth or mild, water-based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

General operat ion

Observe all safety precautions listed in Safety precautions (on page 1-1 the Series 2200 instruments and any associated instruments.

Read and follow all installation, operation, and maintenance information carefully before using the Series 2200 instruments.

Refer to the following sources for complete product specifications:

) and in this topic before using

• Specifications (on page 1-4)

• Series 2200 Programmable DC Power Supplies Specifications (document number SPEC-2200S)

on the Product Information CD-ROM that came with your Series 2200. For the latest version of the specifications, go to the Keithley Instruments website

1. Place the bottom of the instrument on a bench or similar surface. Do not stand the instrument on it's rear panel. Refer to the following figure for an illustration of how to position the instrument.

Do not stand the instrument on its rear panel. This position is unstable and the instrument might tip over and be damaged or fall on someone and cause injury. To avoid damage or bodily injury, place the bottom of the instrument flat on a stable surface.

(http://www.tek.com/keithley).

Figure 1: Place bottom of instrument on flat stable surface

2. Before operating, ensure that the ambient temperature is between +0 °C and +40 °C (+32 °F to +104 °F).

To ensure proper cooling, keep the front, sides, and rear of the instrument clear of obstructions.

Use properly rated load wires. All load wires must be heavy enough not to overheat when carrying the maximum short-circuit output current of the power supply. If there is more than one load, then any pair of load wires must be capable of safely carrying the full-rated shortcircuit output current of the power supply.

To reduce risk of fire and shock, ensure the mains supply voltage fluctuations do not exceed 10% of the operating voltage range.

Do not loosen any screw on this product, except those in the rear connector, which are intended to retain attached external wires to the connector. There are no user serviceable components inside.

Configuring the instrument for your application

The configuration menus (see Configuration menus description (on page 2-9)) include settings, like OVP and Max Volt, that determine the maximum voltage output of the power supply. The menu system also includes settings, like Save Last and Output Recall, that determine how the instrument initializes itself when it is turned on.

This power supply features a constant voltage/constant current automatic crossover. This feature permits continuous operation in the transition from constant-voltage mode to constant-current mode as the load changes. The intersection of the constant-current and constant-voltage modes is called the crossover point.

For example, if the load is such that the power supply is operating in constant-voltage mode, the power supply provides a regulated output voltage. The output voltage remains constant as the load increases until the preset current limit is reached. Then the crossover occurs. At that point, the output current becomes constant and the output voltage drops in proportion to further load increases.

Crossover is indicated by the front panel CC and CV messages. If the CV message appears, the instrument is operating in constant-voltage mode. If the CC message appears, the instrument is operating in constant-current mode.

Crossover from the constant-current mode to the constant-voltage mode also occurs automatically in response to a decrease in load. For example, suppose you are charging a 12 V battery. Initially, the open circuit voltage of the power supply is preset for 13.8 V. A low-battery places a heavy load on the power supply, and it operates in constant-current mode. You adjust the instrument to charge the battery at the rate of 1 A. As the battery becomes charged and its voltage approaches 13.8 V, the load decreases to the point where the battery no longer demands the full 1 A charging rate. The power supply then crosses over to constant-voltage mode.

Rear panel operation

The Series 2200 instrument supports two remote interfaces:

• GPIB (general purpose interface bus)

• USB

The Series 2200 can only be controlled from one remote interface at a time. The unit will remote to the first interface on which it receives a message. It will ignore the other interface until the unit is taken back to local operation.

Connect to an external computer with IEEE-488

This topic contains information about GPIB standards, bus connections, and primary address selection.

GPIB standards

The GPIB is the IEEE-488 instrumentation data bus with hardware and programming standards originally adopted by the IEEE (Institute of Electrical and Electronic Engineers) in 1975. The instrument is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common commands and status model topology.

Connect the GPIB cable

To connect a Series 2200 to the GPIB bus, use a cable equipped with standard IEEE-488 connectors, as shown below.

Series 2200

peration

Programmable DC Power Supplies Reference M anual Section 2: General o

Figure 9: GPIB connector

To allow many GPIB connections to other instruments, stack the cable connectors. Two screws are located on each connector to ensure that connections remain secure. The figure below shows a typical connection scheme for a multi-unit test system.

Figure 10: Series 2200 multiple parallel connections

2200S-901-01 Rev. D / May 2017 2-27

To avoid possible mechanical damage, stack no more than three connectors on any one unit. To minimize interference caused by electromagnetic radiation, use only shielded IEEE-488 cables. Contact Keithley Instruments for shielded cables.

Section

Reference Manual

2: General operation Series 2200 Programmable DC Power Supplies

To connect the Series 2200 to the IEEE-488 bus, line up the cable connector with the connector located on the rear panel. Install and tighten the screws securely, making sure not to overtighten them (see Rear panel at a glance (on page 2-13

) for the location of the connections).

Connect any additional connectors from other instruments as required for your application. Make sure the other end of the cable is properly connected to the controller. You can only have 15 devices connected to an IEEE-488 bus, including the controller. The maximum cable length is either 20 meters or two meters multiplied by the number of devices, whichever is less. Not observing these limits may cause erratic bus operation.

Primary address

The Series 2200 ships from the factory with a GPIB primary address of 22. You can set the address to a value from 0 to 30, but do not assign the same address to another device or to a controller that is on the same GPIB bus (controller addresses are usually 0 or 21).

Terminator

When receiving data over the GPIB, the instrument terminates messages on any line feed character or any data byte with EOI asserted (line feed with EOI asserted is also valid). When sending data, it appends a line feed character to all outgoing messages. The EOI line is asserted with the terminating line feed character.

Connect to an external computer with USB

To connect to an external computer with USB:

1. Install a VISA driver on your computer. This driver is available on the Keithley Instruments website.

2. Connect the instrument to the computer with a USB cable. The computer will then recognize the power supply as a USB device.

Clear and sanitize procedures

This section helps customers with data security concerns to sanitize or remove memory devices from the Series 2200 instrument.

These products have data storage (memory) devices and a data output device (USB port). These instructions tell how to clear or sanitize the memory devices and disable the data output device. The instructions also tell how to declassify an instrument that is not functioning.

Terms

The following terms may be used in this topic.

• Clear. This removes data on media/memory before reusing it in a secured area. All reusable

memory is cleared to deny access to previously stored information by standard means of access.

• Erase. This is equivalent to clear.

• Media storage/data export device. Any of several devices that can be used to store or export

data from the instrument, such as a USB port.

• Nonvolatile memory. Data is retained when the instrument is powered off.

• Power off. Some instruments have a “Standby” mode, in which power is still supplied to the

instrument. For the purpose of clearing data, putting the instrument in Standby mode does not qualify as powering off. For these products, you will need to either press a rear-panel OFF switch or remove the power source from the instrument.

• Remove. This is a physical means to clear the data by removing the memory device from the

instrument.

• Sanitize. This eradicates the data from media/memory so that the data cannot be recovered by

other means or technology. This is typically used when the device will be moved (temporarily or permanently) from a secured area to a non-secured area.

• Scrub. This is equivalent to sanitize.

• User-modifiable. The user can write to the memory device during normal instrument operation,

using the instrument interface or remote control.

• Volatile memory. Data is lost when the instrument is powered off.

Section overview

This chapter explains how to use commands for remotely controlling the Series 2200 instruments. With this information, you can write computer programs to perform functions, such as setting the controls, taking measurements, performing statistical calculations, and exporting data for use in other programs.

Section 3

Remote operation

The Commands listed in alphabetical order (on page 4-2 each command.

Communication interfaces

Your power supply has a USB 2.0 high-speed device port to control the power supply using the USBTMC protocol. The USBTMC protocol allows USB devices to communicate using IEEE-488.2 style messages.

You can also remotely communicate between your power supply and PC over General Purpose Interface Bus (GPIB).

Using the USB

Start by connecting a USB cable (Keithley Instruments Model USB-B - 1) between the USB 2.0 highspeed device port on the rear panel of your power supply and a computer.

In order for the computer to recognize the power supply, a USBTMC driver must be installed on the computer. A USBTMC driver can be installed on your computer by installing Virtual Instrument Software Architecture (VISA), available for download from the Keithley Instruments website (http://www.tek.com/keithley).

Once the USBTMC driver is loaded, your computer will establ ish com munication with the power supply upon USB cable connection.

Using the GPIB

Connector for IEEE-488 (GPIB) operation. Use a shielded cable, such as the Keithley Instruments Model 7007-1 or Model 7007-2.

GPIB requirements

Connect a GPIB cable from the Series 2200 instrum ent to your PC.

Before setting up the power supply for remote communication using the electronic (physical) GPIB interface, you should familiarize yourself with the following recommendations:

• A unique device address should be assigned to each device on the bus. No two devices should

share the same device address.

• No more than 15 devices can be connected to any one bus.

• Only one device should be connected for every 6 feet (2 meters) of cable used.

• No more than 65 feet (20 meters) of cable should be used to connect devices to a bus.

• At least two-thirds of the devices on the network should be on while using the network.

• Connect the devices on the network in a star or linear configuration. Do not use loop or parallel

configurations.

To change GPIB address settings

Your power supply must have a unique device address to function properly. The default setting for the GPIB configuration is GPIB Address 22. If there is more than one GPIB instrument on the bus, you will need to change the default setting on the power supply.

To change the GPIB address settings, do the following:

1. On the instrument front-panel, press Shift and Menu (1).

2. Press the down arrow key or navigation wheel Enter.

3. Press the down arrow key or navigation wheel then press Enter.

4. Press the down arrow key or navigation wheel Enter. The display shows the GPIB address. For example, if the GPIB address is 22, the display will show Address=22.

5. Use the arrow keys, numeric keypad, or navigation wheel press Enter.

Command syntax

You can control the power supply through the GPIB or USB interface using commands and queries. This section describes the syntax these commands and queries use and the conventions the power

supply uses to process them. The commands and queries themselves are listed by group (see

Command groups (on pag e 3-9)) and alphabetically (see Commands listed in alphabetical order

page 4-2)). You transmit commands to the power supply using the enhanced American Standard Code for

Information Interchange (ASCII) character encoding. Appendix A contains a chart of the ASCII character set. The Backus Naur Form (BNF) notation listed in the following table is used in this manual to describe commands and queries.

Command and query structure

Commands consist of set commands and query commands (usually simply called commands and queries). Commands change power supply settings or perform a specific action. Queries cause the power supply to return data and information about its status.

Most commands have both a set form and a query form. The query form of the command is the same as the set form except that it ends with a question mark.

For example, the set command STATus:OPERation:ENAble has a query form STATus:OPERation:ENAble?. Not all commands have both a set and a query form; some commands are set only and some are query only.

A command message is a command or query name, followed by any information the power supply needs to execute the command or query. Command messages consist of five different element types described in the following table.

Programmable DC Power Supplies Reference M anual Section 3:

Commands

Commands cause the power supply to perform a specific function or change one of its settings. Commands have the structure:

[:]<Header>[<Space><Argument>[<Comma><Argument>]...]

A command header is made up of one or more mnemonics arranged in a hierarchical or tree structure. The first mnemonic is the base or root of the tree and each subsequent mnemonic is a level or branch off of the previous one. Commands at a higher level in the tree may affect those at a lower level. The leading colon (:) always returns you to the base of the command tree.

Queries

Queries cause the power supply to return information about its status or settings. Queries have the structure:

[:]<Header> [:]<Header>[<Space><Argument>[<Comma><Argument>]...]

You can specify a query command at any level within the command tree unless otherwise noted. These branch queries return information about all the mnemonics below the specified branch or level.

Query responses

When a query is sent to the power supply, only the values are returned. When the returned value is a mnemonic, it is noted in abbreviated format, as shown in the following table.

Query response examples

Query Response

Command entry

Follow these general rules when entering commands:

• Enter commands in upper or lower case.

• You can precede any command with white space characters. White space characters include any

combination of the ASCII control characters 00 through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through 32 decimal).

• The power supply ignores commands that consists of just a combination of white space

characters and line feeds.

3: Remote operation Series 2200 Programmable DC Power Supplies

SCPI commands and queries

The power supply uses a command language based on the Standard Commands for Programmable Instruments (SCPI) standard. The SCPI standard was created by a consortium to provide guidelines for remote programming of instruments.

These guidelines provide a consistent programming environment for instrument control and data transfer. This environment uses defined programming messages, instrument responses and data formats that operate across all SCPI instruments, regardless of manufacturer.

The SCPI language is based on a hierarchical or tree structure that represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes as shown in the following figure.

Figure 13: Example of SCPI subsystem hierarchy tree

You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings.

Message terminators

This manual uses the term <EOM> (End of message) to represent a message terminator.

USB end of message (EOM) terminators.

See the USB Test and Measurement Class Specification (USBTMC) section 3.2.1 for details. The power supply terminates messages by setting the EOM bit in the USB header of the last transfer of a message to the host (USBTMC Specification section 3.3.1), and by terminating messages with a LF.

When receiving, the power supply expects a LF and an asserted EOM bit as a message terminator.

Abbreviating commands, queries, and parameters

You can abbreviate most SCPI commands, queries, and parameters to an accepted short form. This manual shows these commands as a combination of upper and lower case letters. The upper case letters indicate the accepted short form of a command, as shown in the following figure. The accepted short form and the long form are equivalent and request the same action of the instrument.

3: Remote operation Series 2200 Programmable DC Power Supplies

Chaining commands and queries

You can chain several commands or queries together into a single message. To create a chained message, first create a command or query, then add a semicolon (;), and finally add more commands or queries and semicolons until you are done. If the command following a semicolon is a root node, precede it with a colon (:). The following figure illustrates a chained message consisting of several commands and queries. The chained message should end in a command or query, not a semicolon. Responses to any queries in your message are separated by semicolons.

Figure 15: Example of chaining commands and queries

If a command or query has the same root and lower-level nodes as the previous command or query, you can omit these nodes. In the following figure, the second command has the same root node (STAT:QUES) as the first command, so these nodes can be omitted.

Figure 16: Example of omitting root and lower level nodes

General rules for using SCPI commands

The following are three general rules for using SCPI commands, queries, and parameters:

• You can use single (‘ ’) or double (“ ”) quotation marks for quoted strings, but you cannot use both

types of quotation marks for the same string.

Save and Recall *RCL <NR1>

*SAV (no query form) (on page 4-9)

<NR1> is an integer value in the range from 0 to 40 and specifies the location of setup memory.

*RCL 3 sets the power supply to settings stored in memory location 3.

This command resets the power supply to default settings, but does not purge any stored settings.

Sending the *RST command does the following:

• Returns the power supply settings to the defaults described in

Default setup (on page 2-33).

• Clears the pending operation flag and associated operations

The *RST command does not change the following items:

• State of the USB or GPIB interface

• Calibration data that affects device specifications

• Current GPIB power supply address

• Stored settings

• Output queue

• Service Request Enable Register settings

• Standard Event Status Enable Register settings

• Power-On Status Clear flag setting front-panel LOCK state
