For example, when abnormal friction occurs on the sliding plate of the pointer 1 and local friction increases, the measured value of the load increases in that part, and when the tendency increases, the upper limit of the reference value is reduced. Become beyond. If the sliding portion runs out of oil, the conversion operation time becomes longer, and the measurement data of the operating current near the end of the conversion operation exceeds the upper limit value.
