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 to 55°C,
unless otherwise noted. Warranted specifications include measurement uncertainty
calculated with 95% confidence.
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 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.
– The second group of characteristic types describes ‘statistically’ the 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 specification. These specifications are referred to as typical.
