The following safety precautions should be observed before using this product an d any associated instrumentation. Although some instruments and accessories would normally be used with non-hazardous 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.

Safety Precautions

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 rate d Measurement Category I and Measurement

Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages often associated with local AC mains connections. Assume all measurement, control, and data I/O connections are for connection to Category I sources unless otherwise marked or described in the user documentation.

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 30V RMS, 42.4V peak, or 60VDC 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 1000V, no conductive part of the circuit may be exposed.

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.

08/07

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.

AL W AYS 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.

The instrument and accessories must be used in accordance with its specifications and operating instructions, or the safety of the equipment may be impaired.

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

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 safety earth 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 safety earth ground using the wire recommended in the user documentation. The symbol on an instrument indicates that the user should refer to the operating instructions located in the user documentation. The symbol on an instrument shows that it can source or measure 1000V or more, including the combined effect of normal and

common mode voltages. 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 symbol indicates a connection terminal to the equipment frame.

If this 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 hazards that could damage 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. T o maintain protection from electric shock and fire, replacement components in mains circuits - including the power 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. 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.

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.

2. Use the , , ▲ and ▼ keys to navigate through the reading numbe rs, reading values, and statistics. For any of the buffer st atistics ( maximum, minim um, average, st and ard devia tion) the STA T annunciator is on.

3. Use the EXIT key to return to the normal display.

Changing speed, resolution and filter

RATE — Measurement speed (reading RATE) can be changed for any measurement function

except frequency, period, continuity and diode test. Use the RATE key to select FAST, MEDium or SLOW. Use FAST (0.1 PLC) if speed is of primary importance (at the expense of increased noise and fewer usable digits of resolution). SLOW (10 PLC) provides better noise performance at the expense of speed. MEDium (1 PLC) provides a compromise between noise and speed.

DIGITS — Display resolution can be changed for any measurement function. Use the DIGITS key to select the desired number of digits (3 to 6 ).

FILTER — Filter state (on/off) and configuration can be changed for any measurement function, except frequency, period, continuity and diode test. The FILTER key toggles between filter on (FILT annunciator on) and filter off. After pressing FILTER to enable the filter, you can then enter the filter count (1 to 100), and select the filter type (moving or repeating). (If the FILT annunciator is already on, press FILTER twice before entering the filter count.)

Changing temperature measurement configuration

Press SHIFT and then TCOUPL. Three choices are available using the ▲ and ▼ keys:

• UNITS — C, K or F. Specify units.

• TYPE — J, K or T. Specify thermocouple type.

• JUNC — SIM or CH1. Simulate a reference junction temperature (for direct thermocouple connection to the INPUT), or use the reference junction (channel 1) provided on a switching card. In order to keep the reference calculations update d and accurate, Channel 1 needs to be read periodically.

To assign a value to a parameter, use the ▲ and ▼ keys to scroll to the desired parameter. Select the

key, and use the ▲ and ▼ keys to scroll through and choose the p referred value. Select the

ENTER key to save any changes.

Relative (rel)

Rel can be used to null offsets or subtract a baseline reading from present and future read ings. When rel is enabled by pressing REL (REL annunciator on), the instrument uses the present reading as the relative value. Subsequent readings will be the difference between the actual input value and the rel value. You can define a rel value for each function. Pressing REL a second time disables rel.

Triggers

Factory defaults place the instrument in a continuous (immediate) measurement mode. The instrument can be placed in an external trigger mode where a programmed event is required to cause a measurement (device action).

The instrument is placed in the external trigger mode by pressing th e EXT TRIG key. In this mode, a device action (measurement) will occur when the TRIG key is pressed, a bus trigger (*TRG or GET) is received, or an input trigger via the TRIGGER LINK connector is received. After the device action (measurement), an output trigger occurs and is available at the TRIGGER LINK connector. Refer to the User’s Manual for details on using the trigger link. Pressing EXT TRIG a second time returns the instrument to continuous operation.

Delay — A programmable delay before the device action (measureme nt) occurs is available. It can be set manually or an auto delay can be used. To set a delay, press SHIFT and then DELAY. Use the ▲ and ▼ keys to select AUTO or MANual. If MANual is chosen, enter the duration of the delay and press ENTER. The AUTO delay times are listed in Table 3-2 of the User’s Manual.

Remote Operation Summary

At the factory, the instrument is set for GPIB bus operation at primary address 16 using the SCPI programming language.

GPIB bus — Use the GPIB bus configuration menu to enable or disable GPIB bus operation (ON or OFF), and to check and/or change the primary address (0 to 30) and language (SCPI, 199, or

8842). The configuration menu is accessed by pressing SHIFT and then GPIB. Commands for the SCPI language are provided in Tables 4 through 15. The DDC commands for the 199 and 8842 languages are provided in Tables 16 and 17.

RS-232 interface — Use the RS-232 interface menu to enable or disable RS-2 32 interface operation (ON or OFF), and to check and/or change the baud rate (300 to 19.2k), flow control (NONE or XonXoFF) and terminator (LF, CR or LFCR). Note that only the SCPI language commands can be used over the RS-232 interface.
