The accuracy 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 (°)
A
I
is the correction for current 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)
I
M
is the measured current (A)
