SZ-01A-K3E wide-range standard meter uses the newest electric technique in the world. The core of SZ-01A-K3E is high-speed DSPCPLD and Single Chip Micyoco (SCM), it has the high-speed A/D translator with self-calibration at the same time. It can sample AC signal in high speed and deal with it in special way by DSP, this makes the circuit much simpler. It can calculate and measure AC signal exactly.

Single constant electric pulse output of SZ-01A-K3E advantages the user. It can measure voltagecurrentactive powerreactive powerapparent powerphase anglepower factorfrequency etc at the same time. It takes many kinds of balance technique and methods of data processing, in order to get the 0.02%RD of relative error.

SZ-01A-K3E has strong ability of communication. There are two communication ports on rear board—RS-232 and RS-485, they can connect PC or calibration platform respectively. Connect PC to RS-232 to calibrate the meter. Meter can realize long-distance communication through the telephone line when its RS-232 port is connected to a Modem, thus the meter can send the data to internet and realize long-distance automatic measure.
