Extra Notes - La Crosse Technology COST CONTROL 3362 Operating Manual

15. EXTRA NOTES:

The electrical appliance connected to the Cost Control
should always be operated as normal if forecasting of
the cost is required. If an accurate reading per day,
month or year is required then it is highly
recommended to keep the appliance plugged into the
Cost Control and to operate it normally for at least a
few days. This is so that it can take an average of the
power used and its cost over the time period.
The longer the Total Cost of an appliance is monitored
by the Cost Control, the more accurate any forecast
(day, month, year) or Total Cost reading will be. There
are a variety of reasons for this, some of them are:
•
The power supply to the outlet from the
Electric Company is never constant and at
some stage will vary slightly. For example,
if electricity varies by 1% for every 1 second
of usage and the Cost Control is used for
only 5 minutes then the cost forecast will not
be as accurate compared to use for 3 hours
with the same variation of 1% for every 1
second in the power supply.
•
Some electrical appliances use more
electricity when first turned on than others
and the amount of electricity it uses will
decrease the longer it is left operating
(commonly referred to as "Warming up").
