Abstract
A portable test meter is disclosed for measuring, calculating, recording and monitoring significant system parameters for a local communication network of the type used in industrial automation applications. The meter is disclosed in the context of a network employing the DeviceNet protocol. For each network parameter of interest, a rotary switch selects a desired one for display. An auto search mode selectable by the operator, increments through selected network parameters and compares measured or calculated values against stored data representing acceptable, marginal, or unacceptable conditions, and an associated visual indicia is displayed for each unacceptable or margin condition detected.
