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 fi re, 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. 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 offi ce for information.
Unless otherwise noted in product-specifi 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 affected, the board should be returned to the
factory for proper cleaning/servicing.
