TOU Glossary

Self-Read

The SEL-734 copies and stores the present values in demand and energy

registers.

Total Calculation

The meter calculates a total energy value according to the following Total

Calculation setting options:

➤ Delivered

➤ Received

➤ Delivered + Received

➤ Delivered – Received

Total MWH, MVARH

Received

The total number of received MWH/MVAR hours recorded during this season.

These energy values are unrated registers, accumulated without regard to rate.
