How is MTBF Measured?
For newer products where the data is not statistically stable, Schneider Electric may provide MTBF based on field data from a similar item or data based on predicted product population and forecasted failure rate. An aggregation of operating hours is calculated based on a group of meters with a given time period. Failures are summed from customer returns but taking into account of improvements in new designs and manufacturing processes.

MTBF is calculated as:

MTBF= Predicted Operating hours / Predicted Number of failures.

The predicted MTBF on the ION 8650 is 280 years.
