control power is applied. The PQMII updates this value every hour based on the
previous 24-hour period. This information will be lost if control power to the PQMII is
removed.
• REAL ENERGY COST: This message displays the total cost for the real energy
accumulated since the
TIME OF LAST RESET date.
• REAL ENERGY COST PER DAY: Displays the average cost of real energy per day from
time of last reset to the present. The cost per kWh is entered in the
