METER CERTIFICATION PRIOR 2014
The TID rollover functionality could not be tested prior to 2014, due to a lack of appropriate testing infrastructure
The TID rollover functionality has been a requirement since 1993, so all meters should comply
There is a small risk that some of these meters might not behave correctly when a TID rollover key change is performed
The STS Association is assisting with identifying these meters and provides free of charge services to re-test samples of these meters
