Pakutanga kwegore idzva, Merrick anoda kutenda vese vatengi vatsva nevakuru nerutsigiro rwavo uye kuvimba nesu mugore rapfuura, izvo zvakaita kuti tive nemhedzisiro yakanaka.Panguva imwecheteyo, Merrick anonyanya kutarisisa nezvekuvandudza kwesainzi uye tekinoroji, kuisa mari yakawanda yevanhu uye zviwanikwa mukutsvagisa nekuvandudzwa kwezvigadzirwa zvitsva, zvichiita kuti zvigadzirwa zvive nesainzi, otomatiki uye nehungwaru.
Rk9930 yakatevedzana programmable grounding resistance tester inotora yakakwira-kumhanya MCU uye hombe-yedhijitari yedunhu dhizaini yemhando yepamusoro-yekuchengetedza kuchengetedza tester.Ikozvino inobuda inotora mhinduro yehardware uye yakanyanya-kumhanya MCU yekudzora tekinoroji kuita kuti inobuda igadzikane uye yakavimbika.Ikozvino inobuda inofambiswa neDDS + simba amplifier, iyo yakabuda waveform yakachena uye kukanganisa kudiki.Inogona kuratidza kukosha kwezvino uye kukosha kwekupikisa munguva chaiyo, uye ine basa rekugadzirisa software.Iyo yakashongedzerwa neyakasiyana-siyana yekusangana.Zviri nyore kuumba yakazara bvunzo sisitimu nekombuta kana PLC.Inogona kukurumidza uye nenzira kwayo kuyera kuchengetedzwa kwemidziyo yemumba, zviridzwa, midziyo yekuvhenekesa, magetsi ekupisa midziyo, makomputa nemichina yeruzivo.Kuenzaniswa nezvigadzirwa zvakafanana pamusika, mutengo weiyi nhevedzano yezviridzwa unofadza, uye une hunotevera maitiro ekuita:
1. 5-inch LCD inoshandiswa kuratidza maitiro, iyo inobata maziso uye intuitive.DDS digital signal synthesis tekinoroji inogamuchirwa kugadzira waveform ine yakagadzikana chaiyo, yakachena uye yakaderera kukanganisa;
2. Kugara kwazvino kubuda: kugadzikana kwehuwandu hwekubuda huri mukati me1%, kuitira kuti udzivise kubudiswa kwezvino kuchinja nekuda kwekupinza kwemazuva ano kusagadzikana uye kuchinja kwekutakura;
3. Neakavhurika redunhu alarm basa.Iyo yakanyanya bvunzo nguva ndeye 999.9s;
4. Nzira ina dzekupedzisira dzinoshandiswa kubvisa pesvedzero yekubata kuramba;
5. Iyo yakabuda frequency ndeye 50 Hz / 60 Hz.Iine alarm basa repamusoro uye rezasi muganhu wekupikisa;
6.ChiChinese neChirungu mitauro miviri yekushandisa interface, inochinjika kune zvinodiwa nevashandisi vakasiyana, inotsigira kuchengetedza kwakawanda, chinja kune akasiyana bvunzo application zvinodiwa.
