(5) Ring network yekuona uye yekumisikidza basa, chiridzwa chinogona kuona akasiyana mhete network kukanganisa mumabhawa maviri ebhazi, kusanganisira yakanaka mhete, isina kunaka mhete, bipolar ring uye bipolar ring, nezvimwewo, uye inogona kuoneka ne waveform kuratidza uye kutungamira kuratidza. kutsvaga chikanganiso chemhete network;
(6) Chishandiso chine amplitude modulation, reset, ikozvino waveform kusarudzwa uye yekushanda mode sarudzo basa, iyo inogona kuona kutsvaga uye nzvimbo yekukwirira kupikisa mhete network kukanganisa.
(7) Bazi rekudzivirira kuyerwa kwekuyerwa uye kukanganisa kukanganisa kwenzvimbo basa, chiridzwa chinoyera kudzivirira kwebazi rega rega kusvika pasi, uye chinogona kuona nzvimbo yekuvharisa kukanganisa mapoinzi kuburikidza ne waveform kuratidza uye kutungamira kuratidza;
(8) Kukanganisa ikozvino spectrum kuongorora basa, mudziyo unonyatso kuburitsa chiratidzo che amplitude yeyero yazvino frequency point, uye inovandudza iyo yekuona chaiyo ne spectrum kuongorora basa rekuchinja ikozvino nekukurumidza FFT shanduko;
(9) Ammeter basa, mudziyo unogona kushandiswa seyepamusoro-chaiyo ammeter, uye ikozvino kuyerwa kwechiyero kunogona kusvika 0.01mA;
(10) Waveform curve kuratidza uye kutungamira kuratidza basa.Paunenge uchishandisa detector kuona bazi rakayerwa, rinoratidza shanduko yazvino yebazi rakayerwa muchimiro chewaveform curve pachiratidziri, izvo zviri nyore kuti mushandisi aone chikanganiso nekukurumidza uye nemazvo.Tsvaga kutungamira kwenzvimbo yekukanganisa kana paine mhete yemhete uye pasi pasi.
●High kuvimbika dhizaini
Chishandiso chinotora kunze kwenyika 32-bit microcontroller seyo huru sisitimu, uye dhizaini yehardware inoteedzera simba uye electromagnetic inoenderana zviyero.Iyo yemukati redundancy modhi inogamuchirwa kuti ive nechokwadi chekuvimbika kwechishandiso uye mudziyo uri mukuyedzwa.
●Kunyatsosarudzwa kwezvinhu
Chishandiso chinotora muunganidzi wepamusoro-soro sechikamu chekutora chiratidzo, uye sampling yevoltage inotora yakakwirira-chaiyo inotengeswa kunze analog-digital conversion chip, voltage uye impedance zvinoyerwa nemazvo;
●Humanized munhu-kombuta yekudyidzana interface
Zvose analyzer uye detector inoshandisa TFT liquid crystal display kuti vashandisi vaone ruzivo;
Iko kushanda kuri nyore uye nekukurumidza, uye kana kuonekwa kwematavi akasiyana-siyana kwaitwa, bhatani rimwe chete rekutanga rinogona kupedzwa;
Mhedzisiro yebvunzo yakatwasuka uye mhedzisiro yebvunzo inogona kuunzwa kumushandisi mune akasiyana mafomati ekuratidzira, anosanganisira grounding kana kwete waveform, insulation level, insulation kuramba, kuvuza ikozvino, uye ruzivo rwekutungamira.
●Hungwaru kuona uye kuzivikanwa system
Iyo analyzer inoziva yega system voltage level;
Iyo analyzer inogona kuona iyo mhete yekukanganisa chikamu;
Mushure meiyo detector uye analyzer ruzivo rwakabatana kamwe chete, haizokanganisike nekuona kureba;
Kana iyo detector ichiongorora, muunganidzi anogona kusungirira tambo imwe chete yemagetsi kana kusungirira tambo dzemagetsi akawanda kuti uvandudze kugona kwekuona;
Mushure mekunge detector test yapera, kana bazi rakaedzwa riine mhete yemhete kana kukanganisa kwekudzivirira, ruzivo rwekutungamira kwechikanganiso chinoenderana nenzvimbo yekuedzwa inotarwa.
●Yakazara yekuyedza basa uye kugona kubata zvikanganiso
Iyo isina waya data data transmission module inovakwa pakati peanalyzer uye detector yekutaurirana.Basa rekuyedza uye ruzivo rwekuratidzira rwakakwana, uye rinogona kubata neakasiyana mhete network uye kukanganisa kwekudzivirira muDC system.
Iyo analyzer ine akasiyana-siyana akabatanidzwa maitiro ekushanda nekusarudza mabasa e "Amplitude Modulation", "Waveform" uye "Mode", iyo inogona kuchinjika kune dzakasiyana siyana dzakaoma mamiriro ekushandisa.
●Kuchengetedzwa kwepamusoro
Chishandiso chinotora iyo micro-amplitude yekuona siginecha uye yakakwira-resolution DC yekuona muunganidzi kuti aone kutadza kuona nekumisikidzwa, uye haina pesvedzero paDC system.
