13、urrent, voltage, meter constant, meter ip, etc.3）led indicatormeters have three led indicator lights; the colors and functions are as follows:l pulse: pulse outputl warning: abuse (tampering)l power: power supply status and low credit information. for low credit, the color turns to red and blinks3.3

14、 measurement and monitoringmeters can measure, record, and display the voltage, the current (included the n wire), the power, and the power factor at present. the error is less than 1.3.4 load controlthere are two relays, which are controlled the l and the n wires. when the remaining credit is zero,

15、 the relay is disconnected. after inserting the credit token, the relay is connected.it can detect the load power automatically. if the overload lasts continuously for 45 seconds, the relay will disconnect, and connect again automatically after 150 seconds.within 30 minutes, if the overload occurs a

16、t times with the accumulated time of 45 seconds, relay will disconnect, and connect again automatically after 150 seconds.when the accumulated time of overload is less than 45 seconds, the data of the accumulated time is reset back to zero.within 30 minutes, if the overload occurs 5 times in success

17、ion, the relay will disconnect, and connect again automatically after 45 minutes.3.5 key-padthe key-pad is standardized with 3x4 arrangement, and each key can be operated at least 2, 0000 times. users can input the electricity purchase token, and can also inquire electric parameters or related infor
