PURPOSE: A method for measuring a display amount of a weighting machine is provided to receive and store data of measured amount of electricity, gas and water supply synthetically by use of a complex meter reading part. CONSTITUTION: In a method for measuring a display amount of a weighting machine, a complex meter reading part receives a meter reading request message corresponding to an electricity radio frequency(RF) weighting machine, and checks whether data indicating the amount of used electricity exists in the electricity RF weighting machine(500). If the data does not exist, error information is displayed through a display part(501). If the data exists, a measuring response message is stored in a memory, and then is transferred to a handy terminal(502). The complex meter reading part receives a meter reading request message corresponding to a gas RF weighting machine, and checks whether data indicating the amount of used gas exists in the gas RF weighting machine(503). If the data does not exist, error information is displayed through the display part(504). If the data exists, a measuring response message is stored in a memory, and then is transferred to the handy terminal(505). The complex meter reading part receives a meter reading request message corresponding to a water supply RF weighting machine, and checks whether data indicating the amount of used water supply exists in the water supply RF weighting machine(506). If the data does not exist, error information is displayed through the display part(507). If the data exists, a measuring response message is stored in a memory, and then is transferred to the handy terminal(508).
