Every itron VFD is manufactured under a quality assurance system, that is not only continuous (as explained in the previous paragraphs of this note) but also constantly upgraded and improved.
To aid in this improvement process, Noritake uses the following trouble shooting system (see Table 5), to instantly identify and react to any new problems, even before they occur in production.
