Chapter 1.General introduction
It is used to measure and disaply the direct reading of frequency values in the electrical line.It can support the analog output,alarm,RS485 communication function by the installation of different function modules. And it can also select the multiple functional modules at the same time to make it with the functions of measurement,alarm,transmission and communication.
