Abstract

PURPOSE: To measure a high-precision metering error in an actual load test by calculating the metering error of a metering instrument to be tested on the basis of the metering error of a standard instrument corresponding to an input signal and the metering error of the object instrument from the standard instrument.
CONSTITUTION: A metering pulse signal P and a standard metered value signal M inputted to an input/output part 11 are stored in a memory 14 temporarily under the command of a CPU12. Further, outputs of the transformer circuit and current transformer circuit of the standard instrument 20 are converted by an A/D converting circuit 30 into digital signals, which are counted by a counting circuit; and the counted value is stored in the memory 14 to calculate the mean values of a load voltage and a load current during an error measurement. Then, the CPU12 performs arithmetic on the basis of the metering pulse signal P and standard metered value pulse signal M to calculate the error ε1 of the object instrument 3 from the standard instrument 20. Then, errors ε2 and ε3 of the standard instrument 20 are calculated from the mean values of the load voltage and load current and added to find the real error of the object instrument 3.
