What is a set of meter readings where the surveyor must investigate or perform a certain task?

A set of meter readings requiring investigation typically involves discrepancies or anomalies detected in the data, such as unusually high or low consumption patterns, abrupt changes in usage, or readings that exceed expected limits. The surveyor must then analyze these readings to identify potential issues, such as leaks, equipment malfunctions, or unauthorized usage. This may involve field inspections, checking equipment calibration, or engaging with customers for feedback. The goal is to ensure accurate data collection and address any underlying problems.
