Abstract: PURPOSE:To facilitate the handling of a current meter and to shorten its measurement time by providing a device which discriminates the output signal level of a photoelectric converting element, a device which counts its frequency, a device which performs automatic control, etc. CONSTITUTION:A photomultiplier tube 12, a high-voltage power source 14, discriminators 17 and 18, pulse counting parts 19 and 20, a step voltage generation part 21, etc., are provided. Then, when the output voltage of the power source 14 is too low, the frequency of the high-level output signal of the photo multiplier tube becomes too low because the sensitivity of the multiplier tube 12 is low. Consequently, output pulses of the discriminators 17 and 18 are both less, the counting part 19 generates no output, and the counting pat 20 outputs a single pulse. Then, the generation part 21 receives the output of the counting part 20 to generate a positive step voltage, so the output voltage of the power source 14 rises. This series of operation is repeated at the set period of the pulse counting part until the output voltage of the high-voltage power source becomes proper and the sensitivity of the multiplier tube 12 increases to obtain a sufficient output level and frequency.
