Additional Compliance
UL 61010B-1. Safety requirements for electrical equipment for measuring, controlling
and laboratory use.
IEC61010-1/A2:1995. Safety requirements for electrical equipment for measurement,
control, and laboratory use.
IEC 61010-2-032:1995. Particular requirements for hand-held current clamps for electrical

Installation (Overvoltage) Category
Descriptions
Terminals on this product may have different installation (overvoltage) category
designations. The installation categories are:
CAT III. Distribution-level mains (usually permanently connected). Equipment at this level is
typically in a
fi
xed industrial location.
CAT II. Local-level mains (wall sockets). Equipment at this level includes appliances,
portable tools, and similar products. Equipment is usually cord-connected.
CAT I. Secondary (signal level) or battery operated circuits of electronic equipment.
Pollution Degree Descriptions
A measure of the contaminates that could occur in the environment around and within a
product. Typically the internal environment inside a product is considered to be the same
as the external. Products should be used only in the environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs. Products in
this category are generally encapsulated, hermetically sealed, or located in clean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a
temporary conductivity that is caused by condensation must be expected. This location
is a typical of
fi
ce/home environment. Temporary condensation occurs only when the
product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution that becomes
conductive due to condensation. These are sheltered locations where neither temperature
nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
Pollution Degree 4. Pollution that generates persistent conductivity through conductive
dust, rain, or snow. Typical outdoor locations.
