188.8.131.52 ANGL Test
The accuracy is given as:
AT = AR+AC+AV+AI
AT is the total accuracy (%)
AR is the basic relative accuracy (%)
AC is the calibration accuracy (%)
AV is the correction for voltage level (%)
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 = 0.03 + (0.0000005% x FM)
AV = 0.03 + (0.000003% / VM )
AI = 0.03 + (0.0000003% / IM )
FM is the measurement frequency (Hz)
VM is the measured voltage (V)
IM is the measured current (A)
