220.127.116.11 ILK Test
The accuracy is given as:
AT = AR +AC+AI
AT is the total accuracy (%)
AR is the basic relative accuracy (%)
AC is the calibration accuracy (%)
AI is the correction for current level (%)
The value of AR is given in the table in section 1.1. of this chapter.
The values of the other factors are given below.
AC = 0.1% + (0.0005% x FM )
AI = 0.1% + (0.0000001% / IM )
FM is the measurement frequency (Hz)
IM is the measured current (A)
