Best uncertainties represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The best uncertainty of a specific calibration performed by the laboratory may be greater than the best uncertainty due to the behavior of the customer s device and to influences from the circumstances of the specific calibration. The uncertainties shown relate to voltages and frequencies that lie within ± 10 % of the specified values. 3 The uncertainty quoted on an A2LA certificate will include that of the reference standard plus any uncertainties attributable to the device under test during calibration. 4 For intermediate frequencies between spot points up to, the uncertainty will be the greater of the two. For frequencies greater than, an allowance of 50 % of the greater of the uncertainties of the adjacent known points must be added. The uncertainties are applicable to the calibration of AC voltage sources with 4-terminal output sensing capability and for AC voltage measuring instruments simultaneously connected to the AC voltage source. 5 For intermediate frequencies between spot points up to, where an interpolation of the TVC s reported AC/DC difference is required, an additional allowance of 50 % of the greater of the uncertainties of the adjacent points must be added. The uncertainties are applicable to the calibration of the Datron model 4920 AVMS. (A2LA Cert. No ) 11/1/2004 Page 11 of 12

13 6 For intermediate frequencies between spot points up to, where an interpolation of the TVC s reported AC/DC difference is required, an additional allowance of 50 % of the greater of the uncertainties of the adjacent points must be added. The uncertainties are applicable to the calibration of AC voltage sources with 4-terminal output sensing capability and for AC voltage measuring instruments simultaneously connected to the AC voltage source. 7 For intermediate frequencies greater than 10 MHz, where an interpolation of the TVC s reported AC/DC difference is required, an allowance of 50 % of the greater of the uncertainties of the adjacent known points must be added. The uncertainties are applicable to the calibration of AC voltage measuring instruments with 50 Ω input terminations. 8 Using the 4953 shunt above 11 amperes: The shunt in the 4953 is specified with a thermal resistance of 3 C per watt and a temperature coefficient of 3 parts in 10 6 per C. This means for every watt of power dissipated it heats by 3 degrees (corresponding to a 3 rise at 10 A), and for every degree of temperature change its value changes by 3 parts in So, at 20 amperes it will heat by 12 degrees and change by 36 parts in 10 6 (additional uncertainty). The 4953 is actually rated for 11 amperes continuous usage. A good rule of practice is 1 to 10. If the 4953 is used of 1 minute above 11 amperes, then allow it to cool for 10 minutes before using it again. (A2LA Cert. No ) 11/1/2004 Page 12 of 12
