Functions
|
Basic function
|
Monitor device system time, total voltage, output total current, power, energy, each channel voltage, current, power, energy;
|
|
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 one digital change.

|
Alarm function
|
DC voltage output low alarm,DC voltage output high alarm,one
power down alarm, module voltage loss alarm, metering branch
error alarm, internal program error alarm, clock error alarm,
memory failure alarm, AC input power failure alarm
