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 prec autions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentat ion for complete product specificat ions.

If the product is used in a manner not specified, the protection provided by the pr oduct 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 t hat the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its i ntended 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, s etting 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 pe rsonnel.

Service personnel are trained to work on live circuits, perform safe i ns tallations, and repair products. Only properly trained service personnel may perform ins tallation and service procedures.

Keithley products are designed f or use with electrical signals that are m easurement, control, and data I/O c onnections, with low transient overvoltages, and mus t not be directly connected to mains v oltage or to voltage sources with high transient overvoltages. Measurement Cat egory II (as referenced in IEC 60664) c onnections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be mar ked as category II or higher.

Unless explicitly allowed in the spec i fications, operating manual, and ins trument 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 S tandards Institute (ANSI) stat es 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. I n some cases, connections must be exposed to potential human contact. Product operators i n these circumstances must be trained t o 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 circuit may be exposed.

Do not connect switching cards direc tly to unlimited power circuits. T hey 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 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 jumpers 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 c ircuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or rem oving 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 (ear th) ground. Always make measurements with dry hands while standing on a dry, insul ated surface capable of withstandi ng 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 instructi ons, the protection provided by the eq uipment may be impaired.

Do not exceed the maximum signal lev els of the instruments and accessories. Maximum signal levels are defi ned 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 fi r e hazard. Chassis connections must only be used as shield connections for measuring circuits, NOT as protective ear th (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 r equires the use

of a lid interlock.

If a

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

The symbol on an instrument means caution, risk of hazard. The user must refer t o the operating instructions located in t he user documentation in all cases where the symbol is marked on the instrument.

The

symbol on an instrument means warning, risk of electric shock. Use standard safety precautions to avoid personal

contact with these voltages.

The

symbol on an instrument shows that the sur face may be hot. Avoid personal cont ac t to prevent burns.

The symbol indicates a connection termin al to the equipment frame.

If this

symbol is on a product, it indicates th at mercury is present in the display l am p. 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 hazards that might result in personal inj ury or death. Always read

the associated information very car efully before performing the indicated procedure. The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may

invalidate the warranty.

The CAUTION heading with the

symbol in the user documentation explains hazards that could result in moder ate or minor injury or damage the instrument. Always read the associated information v ery carefully before performing t he indicated procedure. Damage to the instrument may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans. Before performing any maintenance, disconnect the line cord and all test c ables. 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. 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 instrum ent 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 equival ent to the original component (note that selected parts should be purchased only through Keithley to maintain accuracy and f unctionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley office for information.

Unless otherwise noted in product-specific literature, Keithle y 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 degr ee 1 or 2.

To clean an instrument, use a cloth dampened with deionized water or mild, water-based cleaner. Clean the ext erior 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 acc or ding to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factor y for proper cleaning/servicing.

Instrument power

Follow the steps below to connect the DMM6500 to line power and turn on the instrument. The DMM6500 operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz, 60 Hz, or 400 Hz. It automatically senses line frequency. Make su re t he operating voltage in your area is compatible.

The fuse is set to the expected voltage at the factory. M ake sure that the correct line voltage is displayed on the power module. See "Line voltage v erification" in the Model DMM6500 Reference Manual for more information.

You must turn on the DMM6500 and allow it to warm up for at l east 30 minutes to achieve rated accuracies.

Operating the instrument on an incorrect line voltage may cause damage to the instrument, possibly voiding the warranty.

The power cord supplied with the DMM6500 contains a separate protective earth (safety ground) wire for use with grounded outlets. When proper connections are made, the instrument chassis is connected to power-line ground through the ground wire in the power cord. In the event of a failure, not using a properly grounded protective earth and grounded outlet may result in personal injury or death due to electric shock.

Do not replace detachable mains supply cords with inadequately rated cords. Failure to use properly rated cords may result in personal injury or death due to electric shock.

Before installing the instrument, disconnect all external power from the equipment and disconnect the line cord. Failure to disconnect all power may expose you to hazardous voltages, which, if contacted, could cause personal injury or death.

Connect the power cord

When you connect the power cord, the instrument m ay power on, depending on the state of the front-panel POWER switch.

To connect the power cord:

1. Connect the female end of the supplied power cor d to the AC receptacle on the rear panel.

You can only use one communications interface to control the DMM6500 at a time. The USB connection takes precedence over LAN con nections. For other communications interfaces, the f i rst interface on which the instrument receives a me ssage takes control of the instrument. If another interface sends a message, that interface can tak e control of the instrument. You may need to enter a password to change the interface, depending on the selected interface access.
