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 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, remove power from the 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 and servicing.

Power and environmental specifications
For indoor use only.
0 °C to 50 °C (32 °F to 122 °F), 70 % relative humidity
up to 35 °C (95 °F); derate 3 % relative humidity/°C,
35 °C to 50 °C (95 °F to 122 °F)
Carefully consider and configure the appropriate output-off
state, and source and compliance levels before connecting the
instrument to a device that can deliver energy. Failure to
consider the output-off state and source and limit levels may
result in damage to the instrument or to the device under test.
