LRS-3100 Series Single-Phase Multi-Function Standard Meter

I. Functions and characteristics
* Adopt advanced DSP and FPGA chips and advanced sampling technology and algorithm to realize the high-speed and real time measurement function and make itself have super accuracy and strong functions.
* Internal board adopting the SMT surface paster, with higher reliability.
* Large LED screen with mimic and clear interface.
* RS232 interface, convenient for connecting with computer, controlling and reading the internal parameters.
* Capable of measuring active and real reactive power.
* Capable of measuring the electricity parameters, such as voltage, current, power (apparent, active and reactive), phase, power factor and frequency etc.
