PURPOSE:To obtain a parallel resistance value for adjustment within a desired range by connecting a parallel resistance for bias to one side of a bridge side with regard to a circuit where a series resistance and a parallel resistance for zero-point adjustment and zero-point shifting temperature compensation are connected to a resistance element of a full bridge circuit. CONSTITUTION:A series parallel for adjustment 54 is connected to a resistance element 12 on a bridge circuit 10. A parallel resistance 56 for bias is connected to a side where a resistance element 16 is connected, and also a parallel resistance 58 for adjustment is connected to a side where a resistance dement 18 is connected. Then a resistance value of a parallel resistance 56 for bias is beforehand selectively set at a value where adjustment is easy. Following this process, the series resistance 54 and the parallel resistance 58 are adjusted to adjust the zero point and the zero- point shifting temperature compensation. A fixed resistance 60a, 60b and a variable resistance 62 are set for fine adjustment of the zero point. In addition, a resistance 64 is provided for span adjustment. |
