METHOD OF MANUFACTURING MULTIPOINT TYPE BALANCE, AND MULTIPOINT TYPE BALANCE

摘要

PROBLEM TO BE SOLVED: To sufficiently reduce a period and a cost needed for adjusting a plurality of load cells when manufacturing a multipoint type balance employing the load cells.;SOLUTION: Load cell input terminals A₁, B₁ for applying input voltages thereto and load cell output terminals C₁, D₁ for output of output voltages therefrom are arranged. In the configuration, output adjusting resistors 181, 182 are disposed between the output terminal C₁ and strain gages 14, 15, respectively. Accordingly, resistors newly making up this bridge circuit are not the strain gages 14, 15 but a series combined resistor of the strain gage 14 and the output adjusting resistor 181, and a series combined resistor of the strain gage 15 and the output adjusting resistor 182. Resistance values of the output adjusting resistors 181, 182 are equal to each other. Furthermore, a span adjusting resistor 183, which is a semi-fixed resistor, is disposed between the input terminal A₁ and a bridge circuit input point A₁₀. Terminals corresponding to respective load cells adjusted in the steps are connected to each other.;COPYRIGHT: (C)2010,JPO&INPIT
