PROBLEM TO BE SOLVED: To allow a worker to do easy control work for load signals from a load detector. SOLUTION: After amplified by a differential amplification circuit 5, an analog load signal from the load detector 1 is converted into a digital load signal. When an offset value and a gain value for the digital load signal are set, the worker uses an input device 2 such as a car call button to input set values under a balanced load mode and a full load mode. Load data control means 7 compares the set values with output values for the A/D converter 6 to calculate the offset value and the gain value which are written into a nonvolatile memory 8. |
