Specification definitions
There are two types of product specifications:
• Warranted specifications
• Characteristic specifications
Warranted specifications
Warranted specifications are covered by the product warranty and apply
over 0 °C to 55 °C, unless otherwise noted. Warranted specifications
include measurement uncertainty calculated with a 95% confidence level.
Characteristic specifications
Characteristic specifications are not warranted. They describe product
performance that is useful in the application of the power sensors by
giving typical, but non- warranted performance parameters. These
characteristics are shown in italics or denoted as "typical", "nominal",
or "approximate".
Characteristic information is representative of the product. In many cases,
it may also be supplemental to a warranted specification. Characteristic
specifications are not verified on all power sensors. The types of
characteristic specifications can be placed in two groups:
• The first group of characteristic types describes 'attributes' common to
• The second group of characteristic types describes 'statistically' the
• Typical plots are derived from a population mean from production

all products of a given model or option.
Examples of characteristics that describe 'attributes' are product weight
and 50 Ω input Type- N connector. In these examples, product weight is
an approximate value and a 50 Ω input is nominal. These two terms
are most widely used when describing a product's 'attributes'.
aggregate performance of the population of products.
These characteristics describe the expected behavior of the population
of products. They do not guarantee the performance of any individual
product. No measurement uncertainty value is accounted for in the
specifications. These specifications are referred to as typical.
