2.8.11. Measurements accuracy
1. Current
Measurement range: (0 a 1.2*I
r
)
For I
r
 =1: Class 1 (1% of I
r
)
For I
r
=5: Class 0,5 (0,5%of I
r
)
Protection Range: (0.1 to 200 A)
1 % of the real value for I> 1 A
3 % of the real value for I< 1 A
(In areas where the measurement range and the protection
range overlap, the accuracy is the best one out of both of them).
2. Voltage
Accuracy: 0.5 % of the rated voltage U
r
up to 1.2*V
