General
ADL400 three phase din rail electric meter is a smart meter designed for power supply system, industrial and mining enterprises and utilities to calculate the electricity consumption and manage the electric demand. It features LCD display, high precision, small size and simple installation.
It integrates the measurement of all electrical parameters with the comprehensive electricity metering and management provides various data on previous 48 months, checks the 31st harmonic content and the total harmonic content, realizes the remote communication and the remote control with switching input and relay output and boasts the alarm output.
It is fitted with RS485 communication port and adapted to MODBUS-RTU protocol. ADL400 can be used in all kinds of control systems, SCADA system and energy management system (EMS). The meter meets the related technical requirements of electronic meter in the IEC62053-21standards.

Q: The display power or energy count is inaccurate after the meter powered on.
A: Switch the meter display interface to the power (active power P, power factor λ) interface, and check whether the power display is negative or not. And whether the power factor is between 0.9-0.95, and then check whether the incoming and outgoing wires of the current signal wire are connected reversely (that is, the current the incoming wire must be the same as the incoming wire end of the meter), and consistent with the wiring diagram on the meter.
Q: It cannot communicate with the host computer normally after the instrument powered on.
A: 1. The voltage value between the communication output A and B of the measuring instrument should be between +(4.4-4.5)V .
2. Check whether the communication wiring method is correctly wired according to the wiring diagram (that is the communication terminal A/B of the instrument must be connected with corresponding to communication serial port A/B);
