Safety precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although 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 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 produc t 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 ar e adequately trained.
Operators use the product for its intended function. They must be traine d in electrical safety procedures and pr oper use of the instrument. They must be protected from electric shock and contact with h azardous 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 ar e 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 ins tallation and service procedures.
Keithley products are designed for us e with electrical signals that are measurement, control, and data I/O connecti ons, with low transient overvoltages, and mus t not be directly connected to mains voltage or to voltage sources with high tr ans ient overvoltages. Measurement Categ ory II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certai n K ei thley measuring instruments may be connected to mains. These instruments will be mar k ed as category II or higher.
Unless explicitly allowed in the spec i fications, operating manual, and instrument labels, do not connect any instrument to mains. Exercise extreme caution when a shock hazard is present. Lethal voltage m ay be present on cable connector jacks or test
fixtures. The American National S tandards 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 protec ted 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 c ases, connections must be exposed to potential human contact. Product operators i n these circumstances must be trained to pr otect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 V, no conductive part o f the circuit may be exposed.
Do not connect switching cards direc tly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When conn ec ting sources to switching cards, ins tall protective devices to limit fault current and v ol tage 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 j umpers for possible wear, cracks , or breaks before each use.
When installing equipment where ac cess 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 ca pac i tors before: connecting or disconnecting cables or jumpers, installing or rem oving switching cards, or making int er nal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the c i rcuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstandin g 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 s pecified in the operating instructions, the protection provided by the equipment may be impaired.
Do not exceed the maximum signal lev els of the instruments and accessories . Maximum signal levels are defined in the specifications and operating inf or mation and shown on the instrument panels, test fixture panels, and switching cards.
When fuses are used in a product, replac e with the same type and rating for continued protection against fire hazard. Chassis connections must only be used as shiel d connections for measuring circuits, NOT as protective earth (safet y ground)
connections. If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requir es the use
of a lid interlock.

invalidate the warranty.
The CAUTION heading with the
symbol in the user documentation explains hazards that could result in m oder ate or minor injury or damage the instrument. Always read the associated information very carefully before performing the indicated procedure. Damage to the instrument may invalidate the warranty.
Instrumentation and accessories s hall 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 — including the power
transformer, test leads, and input j ac ks — must be purchased from Keithley. S tandard fuses with applicable national safety approvals may be used if the rating and type are the same. The detachable mains p ower cord provided with the instrument may only be replaced with a similarly rated power cord. Other components that ar e not safety-related may be purchased from other suppliers as long as they are equivalent to the original component (note tha t selected parts should be purchased on ly through Keithley to maintain accuracy and f unctionality of the product). If you are unsure about the applicability of a r eplacement component, call a Keithley office for information.
Unless otherwise noted in product-specific literature, Keithley instruments are designed 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 cloth dampened with deionized water 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 factor y for proper cleaning/servicing.

Remote communications interfaces

Section 3
You can choose from one of several communication i nterfaces to send commands to and receive responses from the 2470.
You can control the 2470 from only one communications interface at a time. The first interface on which the instrument receives a message take s co ntrol of the instrument. If another interface sends a message, that interface can take control of t he inst rument. You may need to enter a password to change the interface, depending on the access mode .
The 2470 automatically detects the type of communications interface (LAN, USB, or GPIB) when you connect to the respective port on the rear panel of t he inst rument. In most cases, you do not need to configure anything on the instrument. In addit ion, you do not need to reboot if you change the type of interface that is connected.

Supported remote interfaces

The 2470 supports the following remote interfaces:
GPIB: IEEE-488 instrumentation general purpose interface bus
Ethernet: Local-area-network communications
USB: Type B USB port
TSP-Link: A high-speed trigger synchronization and communications bus that test system
builders can use to connect multiple instruments in a master-and-subordinate configuration
For details about TSP-Link, see "TSP-Link System Expansion Interface" in t he M odel 2470 Reference Manual.

GPIB communications

The 2470 GPIB interface is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common commands and status model topology.
You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum cable length is the lesser of either:
The number of devices multiplied by 2 m (6.5 ft)
20 m (65.6 ft)
You may see erratic bus operation if you ignore these limits.

Install the GPIB driver software

Check the documentation for your GPIB controller for information about where to acquire drivers. Keithley Instruments also recommends that you check the website of the GPIB controller for the latest version of drivers or software.
It is important that you install the drivers before you connect the hardware. This prevents associatin g the incorrect driver to the hardware.

Install the GPIB cards in your computer

Refer to the documentation from the GPIB controller vendor for information about installing the GPI B controllers.

Connect GPIB cables to your instrument

To connect a 2470 to the GPIB interface, use a cable equi pped with standard GPIB connectors, as shown below.
