Current Usage
The
Current Usage
screen shows the rate
of energy consumption and the estimated
cost per hour in dollars (or cents, if it is
less than one dollar). The estimated cost is
calculated from the current price per unit
multiplied by the current rate of energy
consumption. The data is updated from
the meter every 8 seconds while this
screen is shown.
This is like the speedometer in your car; it shows you how fast you are consuming
energy.
Daily Totals
The
Daily Totals
screen shows your
accumulated totals in graphical and
numerical format for energy consumption
and estimated cost for the current day and
the previous day. The current day
(“Today”) shows a running total from the
start of the day (midnight) up to the
present. At midnight, today’s totals will be
transferred to “Yesterday”, and a new
running total is started.
The graphs show hourly data, with a bar for each hour. The height of the bars is
proportional to the number of kWh consumed for each hour. The graphs are auto-
scaling, and meant to show relative, rather than absolute values. The small number
near the top of the center line indicates the value (in kWh) of the highest bar in the
graphs.
When you first start up your
EMU-2
™, there will be no Yesterday data, so you will
dashes in the place of numbers until the end of the first day.
