Probably so they have some assurance that the new folks won't plop into the welfare/health system.

Not too much meat in there, except two rather scary remarks, I was just hoping it might get a confirmation of "yes, that is the meter" -- from which, you can dig deeper. > quote: "solid-state meter platform" and "Digital Multiplication > Measurement Technique". There aren't a helluvalot of different ways to go about doing this. One is to concurrently (potential source of error) "digitize" I & V and "multiply and accumulate". (note, the design may reduce this to one multiply per cycle :< ) Another is to implement a 4Q (?) analog multiplier and sample (and accumulate) the result. I worked on a meter design that used synchronous VtoF converters to do the sampling and multiplication. Then, just "count" the result. (i.e., the whole DAS can be then be shrunk/integrated) The *real* problem is meeting environmental tolerances as well as cost and MTBF. The rest is a "high school" project. > That can spell trouble if not designed right. Yup. I think with today's loads, it's real easy to make assumptions that can lean one way or the other in terms of favoring the consumer or the producer. :< It's amazing that old "mechanical" meters were able to get the accuracies htey could over the operating ranges! |
