VOC TEST
The accuracy for measuring open circuit voltage is given as:
where
A
T
is the total accuracy (%)
A
R
is the basic relative accuracy (%)
A
C
is the calibration accuracy (%)
A
V
is the correction for voltage level (%)
The value of A
R
is given in the table in section 1.1 of this chapter
The values of the other factors are given below.
where
F
M
is the measurement frequency (Hz)
V
M
is the measured voltage (V)
A = V
