| Popis: | The article presents the results of the first round of interlaboratory comparisons in a type of electrical measurements — an AC voltage rated at 3 V in the frequency range from 20 Hz to 1 MHz. Comparison of the measurement results obtained during the calibration of the precision thermoelectric voltage converter ПНТЭ-6А by five laboratories was done radially for nine months in 2016—2017. The deviations of the results obtained by each laboratory are determined and their correctness is evaluated taking into account the uncertainty of the measurements with the help of a modified criterion on the operation statistics for the selected frequencies. |
