I read a quick question about WaveRIDER as to whether a Gauge R&R Study has been done and have the following to offer: We (the Manufacture) looked into GR&R as a possible means to "qualify" the validity of the measurements made by the WaveRIDER and elected NOT to use this method because it seems to apply best to a very limited set of condition not necessarily represented by a WaveRIDER. Combine that with limited understanding of GR&R (except those who have made it their ambition to understand it) and what the results really mean, we found they would only serve to confuse general users. Also, GR&R is intended to evaluate the entire process: the machine, the measurement tool, and the operators. Thus any results we get would only represent our process, and any results you get your process, and so on. We have, however, done some Cpk studies on the WaveRIDER's various measurement parameters which yielded values 1.5 and up, depending on the measurement. These studies served only to prove that our specs for the WaveRIDER are valid. In general, the WaveRIDER measures temperature within +/-1 degree C and time to 1%+/-0.1 seconds. Thanks for the question. ^^^^^^^^^^^^^^^^^^^^^^^^^ Paul Austen Project Engineer New Product Introduction Team ECD Inc 4287A SE International Way Milwaukie OR 97222 Phone: 503.659.6100 Fax: 503.659.4422 Email: [log in to unmask] Web: www.ecd.com ^^^^^^^^^^^^^^^^^^^^^^^^^ ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC web site (http://jefry.ipc.org/forum.htm) for additional information.
