Method for calibrating scales

A method for calibrating a scale having a weight-determining weighing system with a processor-controlled computer and with a memory unit for storing information regarding gravitational acceleration (g), using a wire or wireless telephone network, comprising the steps of:

• transmitting data regarding the location or place of operation of the scale via the wire or wireless telephone network from the location or place of operation to a receiving location, the data regarding the location or place of operation of the scales being the local area code of the telephone network at the location or place of operation;
• determining the information associated with the location or place of operation regarding the value of the gravitational acceleration at the location or place of operation of the scale on the basis of the data received at the receiving location;
• triggering the scale connected at the location or place of operation to the telephone network by means of a serial interface and a modem, and transmitting the determined information from the receiving location to the computer of the scale at the location or place of operation, where they are stored in the memory unit.
