Di-440 The Modular Analyser
Instrument Concept Single tool for a range of service, maintenance and inspection applications: Condition assessment tool highlights state of machinery today NOT for Predictive Maintenance Ease of use is critical Enables collection of VALID data by nonexperts Should store and record relevant data for the use of veteran analysts A service tool NOT a scientific instrument as such the user interface should be simple Should de-mystify the use of an FFT analyser
Instrument Specification Modules (Tools) on a Common Platform Check to Conformance Basic Analysis - FFT & absolute phase Bump Test Icons 2 channel Signal Recorder Balancer Post-processing s/w on PC Training / Services Future modules
