ADW300 wireless meter is mainly used to measure the three-phase active energy of low-voltage network. It has the advantages of small size, high accuracy, rich functions, etc., and has multiple optional communication modes. It can support RS485 communication and wireless communication modes such as Lora, 2G, NB, 4G, etc., and adds the current sampling mode of external transformer, so as to facilitate users to install and use it in different occasions. It can be flexibly installed in the distribution box to realize the needs of sub-item energy measurement, operation and maintenance supervision or power monitoring in different areas and different loads.

FAQ
Q：What's the biggest advantage of ADW300?
A：ADW300 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi, NB-IoT, LoRa upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW300 will usually be the best option for monitor 3-phase circuits that were far from each other.
Q：How should I deal with RS485 network communication malfunction?
A：First, check if the wiring of RS485 communication line was loosen or wired incorrectly.(like reversely wiring the A,B terminal).
Next,inspect if the meter’s setting of address, baud rate, check bit was correct by using keypads on the meter.
Q：What if LoRa communication of meters malfunctioned?
A：First, use USB to RS485 serial converter to connect the meter with computer. Then use adjustment software to check if setting of meter is on consensus with the setting of master station.(setting of channel and spreading factor--SF)
If setting remain the same, then it might be due to large interference of work site or the excessively far range between meter and host. In that case, it’s recommended to use chuck antenna or set a new master station nearby.
Q：What’s the difference between ADW300 and ADW300W
A：ADW300 current 5A input.
ADW300W has 3 external current transformers and current is less than 100A.
