Functions

Basic function

Monitor device system time, total voltage, output total current,
power, energy, each channel voltage, current, power, energy; LED
indicator display;485 communication

Metering function

Start current: under rated voltage, when the load current value of
the meter doesn’t exceed 1% of the max. current, the meter
starts.
Shunt running current: when there is no current in the current
circuit of the meter, and 85%-125%of the rated voltage is applied
on the voltage circuit, the calculator shall not have more than

Alarm function
