To improve accuracy of spectral measurement when moving a wave length at a high speed in a two-light flux spectrophotometer provided with two detectors.
Before measuring a sample, an impression voltage value to the reference light flux side detector and an impression voltage value to the sample light flux side detector are individually held by performing voltage value storage measurement on respective ones of a light detector arranged on the reference light flux side and a light detector arranged on the sample light flux side. When measuring the sample, the holding reference light flux side voltage value and the sample light flux side voltage value are read out, and are respectively impressed on the reference light flux side light detector and the sample light flux side light detector to properly maintain sensitivity of a detecting system.
