MEASURAND : AC-DC current transfer difference

CURRENT : 10 mA

CCEM-K12

The key comparison reference value, xR, is computed as the weighted average of the results of those participants who have an independent realisation of primary standards for current AC-DC difference and a low reported uncertainty (see Section 6 of the CCEM-K12 Final Report).

At 10 mA, the key comparison reference values are based on the measurements carried out by NMIA, NIST, NRC, PTB, BEV, SP, and VNIIM.

The combined standard uncertainty, uR, of xR is the standard uncertainty of the weighted average (see equation 2 on page 11 of the Final Report).

 

        xR = 2.6 µA/A     2uR = 0.9 µA/A

 

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in µA/A:

Di = (xi - xR) and its expanded uncertainty (k = 2) Ui obtained from equations 4, 5 and 6 on page 11 of the CCEM-K12 Final Report.

The key comparison reference value, xR, is computed as the weighted average of the results of those participants who have an independent realisation of primary standards for current AC-DC difference and a low reported uncertainty (see Section 6 of the CCEM-K12 Final Report).

At 5 A, the key comparison reference values are based on the measurements carried out by NMIA, NIST, NRC, INTI, PTB, BEV, JV(except at 10 Hz), SP, NMC and VNIIM(from 10 Hz to 10 kHz).

The combined standard uncertainty, uR, of xR is the standard uncertainty of the weighted average (see equation 2 on page 11 of the Final Report).

 

        xR = -0.3 µA/A     2uR = 1.4 µA/A

 

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in µA/A:
