    摘要: A measuring instrument includes a detector that outputs a measured value, a digital display unit, an analog display unit having a plurality of display segments, and a display controller. The display controller includes: a tolerance range display unit that lights or blinks display segments corresponding to a preset tolerance range relative to a preset value; a first determiner that obtains a difference between the present value and a present measured value and determines whether the difference is within an analog display range wider than the tolerance range; a difference display unit that lights a display segment corresponding to the last one or the last two digits of the present measured value when the first determiner determines that the difference is within the analog display range; a second determiner that determines whether the difference is within the tolerance range; and an acceptance or rejection display unit that displays a result determined by the second determiner.
