1-9. Specifications
Accuracy is specified for a period of one year after calibration.
Specifications expressed in the "±(2% + 3 digits)" format are saying that the error is a percent of
reading plus a number of least significant digits. The least significant digit is the smallest value that
can be displayed in a range and can be found in the resolution section of the Range and
Resolution specifications table.
When a harmonic error is expressed in the "13
th
(±(2% + 2 digits)) --- 31
st
(±(5% + 2 digits))" form, it
is indicating that there is a linear increase in error from the lower harmonic to the upper harmonic.
The error can be determined as a ratio of the desired harmonic to the number of harmonics in the
expression times the difference in error over the range plus the least error. For example, to find the
22
nd
Harmonic error from the above equation:
((Desired Harmonic - Lower Harmonic) / (Upper Harmonic - Lower Harmonic)) X Error Difference +
Least Error
((22 - 13) / (31 - 13)) X 3 + 2 = 3.5%
Therefore, the error for the 22
nd
harmonic is ±(3.5% + 2 digits).
