All operating, metering constants and algorithms shall not be modified or altered by any external device, communication signal, power outage or any other means which does not require breaking the device’s physical seal. The poorest of all people is not the person without a cent, but the person without a dream. The basic operating constant and the algorithm used in processing the measured quantities shall be stored within the EVT in such manner that they cannot be altered without breaking the device’s physical seal clause
