PROBLEM TO BE SOLVED: To surely switch over to any measuring range in a short time.SOLUTION: A measuring device executes a range-up treatment (steps 14, 19, 22) in which when a measurement value measured by a Ma-th measurement range in the order of the smaller upper limit exceeds the upper limit of the Ma-th measurement range, a (Ma+1)-th measurement range is designated and switched over, and a range-down treatment (step 17) in which when the measurement value measured by a Mb-th measuring range in the order of the smaller lower limit becomes lower than the lower limit of the Mb-th measuring range, a (Mb-1)-th measuring range is designated and switched over, and when a "first condition" that the range-up treatment (step 19) following the range-down treatment (step 17) is executed continuously La=three times is satisfied (step 16), a "third treatment" in which the measurement range designated immediately before is maintained until a "third condition" is satisfied is executed (step 21). |
