Abstract

PURPOSE: To measure with high precision by correcting to obtain an instrumental error near to zero with a correction table to meter integrated usage.
CONSTITUTION: A sensor generates electric pulse signals (a), (b), order of inputs of this electric pulse signals is discriminated in an input circuit 11, and while a signal (c) that discriminates a positive or a negative value is outputted, a step pulse is generated. This step pulse (d) is supplied to a time measuring circuit 21 in a correcting part 20. A correction coefficient for a pulse interval time T is stored previously on the basis of an instrumental error each instrument in a correction table. A controller 22 selects division of the pulse interval time T, supplying the correction coefficient to an adder-subtractor 12 in an integrating part 10. The adding and subtracting circuit 12, while it controls adding or subtracting direction according to the positive or negative discriminating signal (c) from the input circuit 11, adds or subtracts every step pulses to integrate into a reversible integrating counter 13.
