The state estimator requires measurement weights (confidences) that affect its solution. The weights for telemetered and non‐telemetered measurements are selected according to the following:

1 Use individually defined weights for at least some of the telemetered measurements used by the state estimators.

2 Use globally defined weights for at least some of the telemetered measurements used by the state estimators.

The basis for weights applied to at least some analog values used by the state estimator is either a generic percentage metering error or specific meter accuracies.
