PURPOSE:To maintain the continuity of analog signals outputted from a D/A-converting section by providing a function which immediately outputs arithmetic results at the moment when piecewise integration time reaches a set value if the time required by a computer for performing arithmetic operations on effective value, frequency, and phase angle data is shorter than the piecewise integration time or at the moment when the computer completes the arithmetic operations if the time required by the computer is longer. CONSTITUTION:A computer 7 compares the time required by the computer 7 for performing arithmetic operations with piecewise integration time and outputs arithmetic results, namely, the effective, frequency, and phase angle data at the moment when the piecewise integration time reaches a set value if the time required by the computer 7 is shorter than the piecewise integration time or at the moment when the computer 7 completes the arithmetic operations if the time required by the computer 7 is longer. Therefore, the computer 7 can output system phenomena in real time when the time required by the computer 7 is shorter than the piecewise integration time and, when the time required by the computer 7 becomes longer than the piecewise integration time, the computer 7 can output data of correct values even when the delivery of the data is delayed. In addition, tests by an analog device can be performed with high accuracy, because any inroad on next piecewise integration time can be minimized to the utmost. |
