The output pattern is fixed at P01 for 1-phase, 2-wire systems.
HI: Harmonic current, HV: Harmonic voltage, -: No measurement element (fixed at lower limit output)
Various elements can be measured with one unit.
A liquid-crystal display and buttons enable setting flexibility.
Supports power flow measurement (sending, receiving) and can be used for monitoring power generating equipment.
(Active power, reactive power, power factor, active electric energy, reactive electric energy)
Compact size realizes reducted mounting space.
