Case Study – Accuracy vs. Cost Impact on Revenue and Billing
What about PT/CT Errors. Aren’t they worse than the meter? Remember that the total error is cumulative, so you still get improvements with the meter.
Errors can be + or - (Don’t they cancel themselves out) It’s about reducing uncertainty, removing risk and exposure. (That’s why we don’t use 0.5% meters)
