SZ-03A-K3 series standard electrical energy meter of three-phase
wide-band load is a new generation of power electrical energy measuring
meter with high precision of Chinese electric power measuring system.
It gives a full rein of the advantages of micro intelligent based on
the rather mature current self balancing separate multiplier and I/F
power measuring. Advanced singlechip system is capable of error
calculation, beside that, it also adds functions like digit filtering,
linear adjustment of all-range power measuring and digital emendation
of full measuring rang, etc.

In addition to that, according to the needs of on-spot measuring and
laboratory verification platform, the calculated error value could be
displayed while performing measuring of power and electrical energy.

SZ-03A-K3 series standard electrical energy meter is characterized by
high precision, wide-band linear current, good power specialty,
completion and stabilization of zero-points. It is suitable for on spot
and laboratory measuring.
