Accuracy level: class 1
--Active energy: Class 1
Rated voltage 230V
Rated current 10A
Rated frequency 50Hz
Clock precision: ≤ ± 0.5 seconds/day
Shape size 200mm´112mm´71mm（includes big meter end size）

Start The meter can continue to measure electricity in the condition of rated voltage, rated frequency and when power factor is1 and the loading current is 0.4%Ib (class1).
Creeping When adding 115% rated voltage and current loop is disconnected, there
isn’t any electrical energy pulse output.
Basic error (see the following table)
Loading current | Power factor | Basic error (%) 1.0 class |
