Units of measurement matrix

Meter units of measurement settings determine the information that is returned when a meter is interrogated. The measurement quantity that is returned by an interrogation is defined in the meter configuration file (meter program). Use the Units of Measurement Matrix as a guideline to set parameters when configuring groups of meters.
