Then APP will write the balance kWh into the meter , when the meter balance value used up to zero. The meter
will cut off load automatic . when you closed the prepayment function . the meter will recover to normal function
using .
Voltage high limit(V): the overvoltage protection , it will cut off after high than this value.
Voltage low limit(V): the undervoltage protection , it will cut off after lower than this value.
The voltage high limit value must bigger than the Voltage low limit value .
Current high limit(A): the overload protection, it will cut off after high than this value.
For overvoltage/undervoltage/overload event , these status must last 3 s ,so the meter will cut off for
protection .it will delay 60s to confirm the voltage and current recover to normal status after cut off . it will switch
on automatically after confirmed the value recover to normal status.
Starting kWh value :this value is used for calculating the contrast active energy. If the user want to know the
power company meter have run how many after fixed time, you can input the current total active energy of the
power company in here ! for example ,the power company meter is display 50kWh, you can input the 50kWh in
the starting kWh value.
Meter price : how much price for each kWh
History kWh
It will show the last 7 days and 30 days total active energy consumption
And total active energy cost .(only special order in some country)
Meter detail
It will show R.M.S value and bi-direction active energy and contrast active energy
Import active energy : it measure the total positive active energy
Export active energy : it measure the reverse active energy , such as solar power generation , reverse wire
connection , some power generator working .
Normally, the total active energy=| Import active energy | + | Export active energy |
Contrast active energy : it is used for contrast the kWh running with the power company meter or other kWh
meter .
R.M.S value all measure theCurrent instantaneous value
