GVDA Mini cwj mem hom NCV ntse multimeter, Ua tau zoo thiab xav tias zoo. NCV ua haujlwm tau zoo heev thiab zoo ib yam li Fluke NCV tester. Lub multimeter yog qhov zoo, tab sis yuav siv sij hawm ib pliag los txiav txim siab seb nws yog qhov koj ntsuas: tab sis thaum nws txiav txim siab nws zoo li yog qhov tseeb (xyuas tawm tsam kuv AVO). Kuv pom lub kaum sab xis ntsaws rau ntawm qhov kev sim ua rau khaus hauv kev siv nrog cov hlau lead tawm ntawm 90 degrees ntawm lub cev. Kuv tau swapped lawv rau ib lub teeb nrog ncaj plugs. Cov khoom xa tuaj yog raws li GS38. Txhua yam, kev yuav khoom zoo. Yog tias nws ' ploj lawm' ntawm txoj haujlwm, kuv yuav hloov nws.
