| 1%ln≤ l ≤10% ln error±2.5%; l＞10%ln error±2% |
Measurement resolution | Voltage: 0.01V, Current: 0.01A, Power: 0.01kw, Energy: 0.01kwh |
Functions | Basic function | Monitor device system time, total voltage, total current, power energy, each channel voltage, current, power, energy; LED display, RS485 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 start. 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 one digital change. |
Alarm function | DC under-voltage, DC over-voltage, one power down, module voltage loss, metering branch error, internal program error, clock error, memory failure, AC input power failure.
