Operate details
The power is input into the meter through RF card. When the available power in the meter decreases to zero, the meter will automatically cut off the power supply.
Only after the new available power is input through the RF card, the meter can resume power supply.
After the user pays each time, the computer system of the power supply management department can calculate the value of the available electricity that should be recharged to the electricity meter this time according to the user's zero-crossing electricity and the remaining available electricity in the current electricity meter.
• Each end user will have an RF card, that RF card will be used for charging and depositing.
• After finishing the re-charging, the end-user or managers need to use an RF card to touch KWH meter.
• Prepaid meter electricity price can be set by RF card. Officer can record the electricity price and multi-tariff price inside the RF card. Once the RF card touches the KWH meter itself, this information will be recorded into the prepaid meter.
RF card functions
RF cards will not only be used for end-user but also will be used for managers.
Managers can use one blank RF card and give that card a specified function by the Acrel-RFMS system.
The most common functions are:
