Safety

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 speci

 ed 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 de

 ned in the speci

 cations and operating information and shown on the instrument 

panels, test 

 xture panels, and switching cards. 

When fuses are used in a product, replace with the same type and rating for continued 

protection against 

 re 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 

 xture, 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 warning, risk of electric shock. Use standard safety 

precautions to avoid personal contact with these voltages.

The       symbol indicates a connection terminal to the equipment frame.

The         symbol on an instrument means caution, risk of hazard. The user must refer to the 

operating instructions located in the user documentation in all cases where the symbol is 

marked on the instrument.

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

prevent burns.

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 hazards 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.
The 

CAUTION

 heading with the        symbol in the user documentation explains hazards that 

could result in moderate 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 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 

 re, replacement components in mains circuits 

— including the power transformer, test leads, and input jacks — 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 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 to maintain accuracy 

and functionality of the product). If you are unsure about the applicability of a replacement 

component, call a Keithley o

  ce for information. 

Unless otherwise noted in product-speci

 c 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 a

 ected, the board should be returned to the factory for proper cleaning/servicing.
