1 Specifications and Characteristics

Introduction

This chapter details the EPM Series Power Meters specifications and
supplemental characteristics.

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 after a 30
minutes warm- up. These specifications are valid over the power meter's
operating and environmental range unless otherwise stated and after performing
a zero and calibration.
Characteristic specifications
Supplemental characteristics which are shown in italics are intended to provide
information useful in applying the power meter 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 meters. The types of characteristic specifications can
be placed in two groups:
– The first group of characteristic types describes 'attributes' common to all
– The second group of characteristic types describes 'statistically' the aggregate

products of a given model or option.
Examples of characteristics that describe 'attributes' are product weight, and
50  input N-type connector. In these examples, product weight is an
approximate value and a 50  input is nominal. These two terms are most
widely used when describing a product's 'attributes'.
