Performance specifications
Specification definitions
There are two types of product specifications:
• Warranted specifications are specifications which are covered by the
product warranty and apply over a range of 0 to 55 °C unless otherwise
noted. Warranted specifications include measurement uncertainty calculated
with a 95 % confidence.
• Characteristic specifications are specifications that are not warranted.
They describe product performance that is useful in the application of the
product. These characteristic specifications are shown in italics.
Characteristic information is representative of the product. In many cases, it may
also be supplemental to a warranted specification. Characteristics specifications
are not verified on all units. There are several types of characteristic specifica-
tions. They can be divided into two groups:
One group of characteristic types describes ‘attributes’ common to all products
of a given model or option. Examples of characteristics that describe ‘attributes’
are the product weight and ’50-ohm input Type-N connector’. In these examples,
product weight is an ‘approximate’ value and a 50-ohm input is ‘nominal’. These
two terms are most widely used when describing a product’s ‘attributes’.
Conditions
The power meter and sensor will meet its specifications when:
• stored for a minimum of two hours at a stable temperature within the
operating temperature range, and turned on for at least 30 minutes.
• the power meter and sensor are within their recommended calibration
period, and
• used in accordance to the information provided in the User’s Guide.
