I. Qauv Xaiv
1.Category code: D--electric meter
2. Pab pawg code qhia theem kab: D--ib theem; S--peb theem peb kab; T-- peb theem plaub kab. Qhia qhov kev faib tawm ntawm kev siv: D--multi-function; S--electronic; X--reactive zog; Y-- them ua ntej; F--ntau tus nqi.
3. Tus qauv tsim tus naj npawb yog sawv cev los ntawm cov lej Arabic, thiab tus lej tsim ntawm txhua qhov chaw tsim khoom sib txawv. Piv txwv li, tus naj npawb ntawm cov khoom ntsuas hluav taws xob tsim thiab tsim los ntawm Zhejiang Huaxia Instrument Co., Ltd. yog 633, thiab ntawm Zhengtai Instrument Co. yog 666.
