Abstract

A tester for equipment, apparatuses, or components with distributed measurement and analytical functions comprises a simplified test circuit for obtaining key data representative of the operational characteristics of said equipment, apparatus, or component and transmitting these to a sophisticated device capable of other uses, such as a smart phone or tablet computer. The latter analyzes the raw data with reference to values for nominal characteristics or operation of the equipment, apparatus, or component and provides a result indicative of the condition thereof.
