Abstract
PURPOSE: To secure the easy controllability of the measurement, by providing the control circuit, the level setter and the like and then sending the indication of the level meter entering the fixed range to the display unit along with the error message sent to the display unit in case the indication goes out of the above-mentioned range respectively.
CONSTITUTION: The manual control is given to level setter 18 so that the indication of level meter 15 may enter the fixed range near the full scale and in accordance with the switching between switches 12a and 12b. And the control value is obtained. At the same time, the A/D conversion is given to the output of meter 15, and the difference of the A/D conversion value is obtained through control circuit 17 to the switching between switches 12a and 12b. These differences are then added together to obtain the gain or the loss of the measuring instrument to be measured. And in case meter 15 is used in the normal level range, the indication of the level meter is displayed. While the level meter is used outside the normal level, the error message is displayed. In such consititution, the operation can be facilitated greatly since the measurement is possible only via the indication of the standard scale even when the precision measurement is carried out.
