The Energy Tolerance Check is a validation check is an industry standard validation of load profile data against register information. The load profile is integration over a period of time know as the
interval. This interval of integration is recorded inside the device at each interval. The registers count permanently the pulse output from the device. These pulses have an equivalent to transform
them into energy or power units. The energy tolerance check is used to determine how “accurate” the recordings between load profile and the registers are, given a tolerance for the offset of time
when the device is actually read. Since the load profile is stored in a precise moment in time inside the database, the register information is instantaneous, i.e., at the precise moment when the device
is read. Those events normally do not occur at the same moment in time, this offset is the tolerance that must be set by the user.
