Safety Precautions
The following safety precautions should be observed bcforc using
this product and any associated instrumentation. Although some in-
stmmcnt~ and accessories would nomxally bc used with non-haz-
ardous voltages, there are situations where hazardous conditions
may be presem.
This producl is intended for use by qualified personnel who recog-
nize shock hazards and are familiar with the safely precautions rc-
quired to avoid possible injury. Read the operating information
arcfully before using the product.
The types of product users are:
Responsible body is the individual or group responsible for the USC
and maintenance of cquipmcnt. for ensuring that the equipment is
operated within its spccitications and operating limits, and for en-
suring that operators are adequately trained.
Operators use the product for its intended function. They mull be
trained in electrical safety procedures and proper use of the instru-
ment. They must be protected from electric shock and contact with
hazardous live circuits.
Maintenance personnel pafonn routine procedures on the product
to keep it operating, for example, setting the line voltage or replac-
ing consumable materials. Maintenance procedures are described in
the manual. The procedures explicitly state if the operator may pcr-
form them. Otherwise, they should be performed only by service
pxs0”“e1.
Service personnel are trained to work on live circuits, and perform
safe installations and repairs of pmducts. Only properly trained ser-
vice personnel may perform installation and sen%x procedures.
Exercise extreme caution when a shock hazard is present. Lethal
voltage may be present on cable connector jacks or test fixtures. The
American National Sandards Institute (ANSI) states that B 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.
Users of this product must bc protected from electric shock at all
times. The rcsponsiblc body must ensure that users are prevented
accessand/or insulated from every connection point. In some c.xses.
connections must bc exposed to potendal human contact. Product
users in these circumstances must bc trained to protect thcn~scl~es
from the risk of electric shock. If the circuit is capable of operating
at or above 1000 volts, no conductive part of the circuit may be
exposed.
As described in the lntemetional Elcctrmcchnical Commission
(IEC) Standard IEC 664, digital muldmeter measuring circuits
(e.g.. Kcithley Models 175A, 199.2000. 2001. 2002. and 2010) arc

Installation Category I and must not bc connected to mains.
Do not connect switching cards directly to unlimited power circuits.
‘hey arc intended to be used with impcdancc limiled sources.
NEVER connect switching cards directly to AC mains. When con-
necting sources to switching cards. install protective devices to iim
it fault current and voltage to the card
Before operating an inwument, make sure the lint cord is connects
ed to Bproperly grounded power receptacle. lnspcct the connecting
cables. test leads, and jumpers for possible wear, cracks. or brwks
before each use.
For maximum safety, do not touch the product. test cables, or .vly
other inatrumcnrs while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and discharge
any capacitors before: connecting or dirconnecdng cables or jumpy
em, instdting 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 ,,,~a~“rcm~“ts with dry hands while standing on a
dry, insulaled surface capable of withstanding the voltage being
measured.
