sociated information very carefully before performing the
indicated procedure.
The
CAUTION
heading in a manual 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.
To maintain protection from electric shock and fire, replace-
ment 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 compo-
nent, 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 ap-
ply 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., data acquisition board for
installation into a computer) should never require cleaning if
handled according to instructions. If the board becomes con-
taminated and operation is affected, the board should be re-
turned to the factory for proper cleaning/servicing.
