Claim:
1. An electrical characteristic adjustment device for adjusting a characteristic value of an electrical characteristic within a target range, comprising: a microcomputer configured to receive a signal from a device to be adjusted, which can change the electrical characteristic, measure the signal, and acquire the characteristic value of the electrical characteristic; an input interface for inputting data for a first minimum value and a first maximum value indicating the target range of the characteristic value; and a display for displaying a first mark and a second mark, the first and second marks indicating the acquired characteristic value based on their location on an adjustment axis, the location of the first mark on the adjustment axis indicating a value according to a first range of values based on a first scale and the location of the second mark on the adjustment axis indicating a value according to a second range of values based on a second scale, the microcomputer being further configured to: the first range of values is larger than the second range of values, the first scale is smaller than the second scale such that the first range of values and the second range of values occupy the same distance on the adjustment axis, a target value is included within both the first range of values and the second range of values, when the characteristic value is equal to the target value, the first mark and the second mark overlap each other on the adjustment axis such that a center point of the first mark is the same as a center point of the second mark, and the location of the first mark on the adjustment axis is independent of the location of the second mark on the adjustment axis.
