A5 Portable Voltage Current Tester Digital Multimeter

Mafotokozedwe Akatundu

Chipangizo chophatikizikachi ndi chosinthika komanso choyenera kwa akatswiri komanso okonda DIY chimodzimodzi.Multimeters adapangidwa kuti azitha kulingalira.Imakhala ndi kusankha kwamitundu yodziwikiratu, kukulolani kuti musinthe pakati pa zoikamo zosiyanasiyana popanda kusintha pamanja.Izi zimakupulumutsirani nthawi ndikuwonetsetsa zotsatira zolondola nthawi iliyonse.Ndi chitetezo chokwanira chamtundu uliwonse, mutha kukhala otsimikiza kuti ma multimeter anu amatha kuthana ndi ma voltages apamwamba ndi mafunde osawonongeka.Mbali imeneyi imakupatsani mtendere wamumtima komanso imateteza moyo wa chipangizo chanu.Multimeter ili ndi mawonekedwe odziwikiratu omwe amazindikira okha mtundu wamagetsi omwe akuyezedwa, kaya ndi ma volts a AC, ma volt a DC, kukana, kapena kupitiliza.Izi zimathetsa kufunika kosankha pamanja ndikuwonetsetsa kuwerengedwa kolondola kwa zigawo zosiyanasiyana zamagetsi.Multimeter ili ndi chiwonetsero cha LCD chowoneka bwino chokhala ndi manambala a 6000 a miyeso, yopereka zotsatira zosavuta kuwerenga.Zimaphatikizanso chizindikiro cha polarity, ndi chizindikiro "-" cha polarity yolakwika.Izi zimatsimikizira kutanthauzira kolondola kwa zotsatira zoyezera.Ngati muyeso uli kutali, multimeter idzawonetsa "OL" kapena "-OL" kusonyeza kuchulukira, kuteteza kuwerengera zabodza.Ndi nthawi yofulumira yachitsanzo cha masekondi pafupifupi 0.4, mumapeza zotsatira zachangu komanso zolondola pakuthana ndi zovuta.

Kuti musunge moyo wa batri, ma multimeter ali ndi mphamvu yozimitsa yokha yomwe imayamba pakatha mphindi 15 osagwira ntchito.Izi zimathandizira kuwonjezera moyo wa batri ndikukupulumutsani kuti musamasinthe mabatire pafupipafupi.Kuphatikiza apo, chizindikiro chotsika cha batri pazithunzi za LCD chidzakukumbutsani nthawi yomwe batire ikufunika kusinthidwa.Multimeter imatha kupirira malo osiyanasiyana okhala ndi kutentha kwa 0-40 ° C ndi chinyezi cha 0-80% RH.Itha kusungidwanso bwino pa kutentha kwa -10-60 ° C ndi milingo ya chinyezi mpaka 70% RH.Izi zimatsimikizira kulimba komanso kudalirika ngakhale pamavuto.Multimeter imayendera mabatire awiri a 1.5V AAA kuti akupatseni mphamvu yokhalitsa pazofunikira zanu zoyezera.Mapangidwe opepuka olemera magalamu 92 okha (wopanda batire) ndi kukula kophatikizika kwa 139.753.732.8 mm kuti athe kunyamula mosavuta.Ma multimeter athu ndi abwino kwa akatswiri amagetsi, akatswiri ndi akatswiri ochita masewera olimbitsa thupi omwe amafunikira kuyesa molondola pamagetsi osiyanasiyana.Mawonekedwe ake osavuta kugwiritsa ntchito komanso magwiridwe antchito odalirika amapangitsa kuti ikhale yofunika kwambiri pabokosi lanu lazida.
