Abstract

PURPOSE: To maintain the inner pressure of a measuring instrument constant and decrease its output error by providing pressure regulating means for keeping the inner pressure of the measuring instrument constant on the basis of the detection data of inner pressure detecting means.
CONSTITUTION: A gas pressure and a gas temperature inside a measuring instrument are detected by a pressure sensor 23 and a temperature sensor 24, respectively, which are attached to a lower tank 3 and a pressure regulating valve 21 and a pump 22 are regulated so that the gas pressure and the gas temperature inside the measuring instrument can be kept always constant. Since, as a result, the gas pressure and temperature of a spatial transmission portion in a power detecting unit 5 can be also kept constant, a light transmission state can be kept to a constant condition and therefore power measurement error due to a change in the conditions in the measuring instrument can be prevented from being generated. Thus, the power measurement error is prevented from being generated whereby measurement accuracy can be sharply improved.
