220.127.116.11 LVOC Test
The accuracy for measuring open circuit voltage is given as:
AT = AR + AC + AV
AT is the total accuracy (%)
AR is the basic relative accuracy (%)
AC is the calibration accuracy (%)
AV is the correction for voltage level (%)
The value of AR is given in the section 1.1 of this chapter.
The values of the other factors are given below.
AC = 0.03% + 0.001% × FM
AV = 0.03% + 0.001% / VM
FM is the measurement frequency (Hz)
VM is the measured voltage (V)
