function |
basic function |
Monitor device system time, total voltage, output total current, power, energy, each channel voltage, current, power, energy; LED display; 485 communication |
measuring function |
Starting current: Under rated voltage, when the load current value of the meter does not exceed 1% of the maximum current, the meter starts.
Shunt run current: When there is no current in the meter circuit and 85%-125% of the rated voltage is applied to the voltage circuit, the calculator must not have more than one digital change.
