8.Configuration and Dimension
9.Safety Performance
The product meets each safety index and requirement stipulated in GB/T 17215-2008
Display
10.The Energy is displayed in 7 digits, when the meter is on , it will first display the constant and then display the total energy as below.
IV.The Main Functions
1.Energy Measurement
It measures total active energy.With three phase power supply, the meter will keep measuring energy accurately even with one or two phases cut off.
2.Phase missing indication function
Three light indicators are used to indicate whether there is phase missing. Indicators A, B, and C indicate the missing of Phase A, Phase B and Phase C correspondingly.
