2. and Dimension
II.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.
