• I-LCD ibonisa ngokukhawuleza okwangoku, i-voltage kunye namandla asebenzayo kunye ne-backlight;
• Iimpawu ze-LED: Amandla asebenzayo / Amandla asebenzayo / Ukuphazamisa / ukunikezelwa kwamandla.
• Ukulinganisa nokugcina eyona mfuno iphezulu.
• Umsebenzi womlinganiselo weentlawulo ezininzi.
• Ikhalenda kunye nomsebenzi wexesha.
• Ukurekhoda iprofayile yomthwalo.
• Imisebenzi eyahlukeneyo yokuchasana nokuphazamisa: ukuvala ukuvala okuvulekileyo, ukubonwa okuvulekileyo kwe-terminal, ubhaqo olomeleleyo lwemagnethi, njl.
• Ukurekhoda imisitho eyahlukeneyo kubandakanya inkqubo, ukungaphumeleli kwamandla kunye nokuphazamisa, njl.
• Ukukhenkceza yonke idatha ngexesha, ngoko nangoko, ukusetwa kwangaphambili, yonke imihla nangeyure, njl.
• Umboniso wokuskrola ngokuzenzekela kunye/okanye umboniso wokuskrola ngesandla (onokucwangciswa).
• Gcina ibhetri yokubonisa amandla phantsi kwemeko yokucinywa kombane.
• Ugqithiso lwangaphakathi ukuqonda ulawulo lomthwalo ekuhlaleni okanye ukude.
• Amazibuko onxibelelwano:
• -RS485,

-Optical Communication Port, ukufunda imitha oluzenzekelayo;

-I-GPRS, unxibelelwano kunye noMgxininisi weDatha okanye isiKhululo seNkqubo;

-M-ibhasi, unxibelelwano namanzi, igesi, imitha yobushushu, Iyunithi ephathwa ngesandla, njl.

• Ukuqulunqa isisombululo se-AMI (i-Advanced Metering Infrastructure).
• Ukubhaliswa ngokuzenzekelayo emva kokufaka, ukuphucula i-firmware ukude

Block Schematic Diagram

I-voltage kunye neyangoku ukusuka kwigalelo lesampulu yesampulu ehambelanayo ukuya kwimitha yemitha ye-ASIC.Umlinganiselo wetshiphu ukhupha umqondiso wepulse ngokulinganayo kumandla alinganisiweyo kwimicroprocessor yetshiphu.I-microprocessor isebenzisa umlinganiselo wamandla kwaye ifunde i-voltage yexesha langempela, yangoku kunye nolunye ulwazi.

Izikhombisi ze-LED zihlulwe zibe yi-pulse yamandla asebenzayo, i-pulse yamandla asebenzayo, i-alamu kunye nemeko ye-relay, ezisetyenziselwa ukulumkisa abasebenzisi bemeko yokusebenza yemitha.Imitha iqulethe isiphaluka esichanekileyo sewotshi kunye nebhetri.Kwimeko yesiqhelo isijikelezi sewotshi sinikezelwa ukusuka kumbane ngelixa sikwimeko yokunqunyulwa kwamandla izitshintshela ngokuzenzekelayo kwibhetri ukuqinisekisa ukuzinza kunye nokuchaneka kwewotshi.
