1. tuaj yeem kuaj ntau yam AC/DC, tam sim no, voltage, nruab nrab, tus kheej - tuav, thiab teeb liab relays, nrog rau tag nrho cov relay tiv thaiv panels. Nws tuaj yeem kuaj qhov rub-hauv qhov hluav taws xob (tam sim no) thiab tso tawm qhov hluav taws xob (tam sim no) qhov tseem ceeb ntawm ntau yam relays, thiab rub-hauv thiab qhib- tawm lub sijhawm ntawm ntau yam kev sib cuag (ib txwm qhib, ib txwm kaw, hloov pauv, thiab sijhawm- ncua sijhawm). Txhua qhov kev ntsuam xyuas tau ua tiav peb zaug thiab cov txiaj ntsig tau khaws cia. Qhov rov qab coefficient ntawm peb qhov nruab nrab yog txiav txim siab thiab luam tawm. Cov qhabnias xeem tuaj yeem rov muab tso tawm thiab luam tawm.
2. Tau yooj yim sim ntau yam tsis ntawm reclosing relays.
3. Nruab nrog zaus thiab theem ntsuas kev ua haujlwm, nws tuaj yeem ntsuas qhov zaus ntawm qhov tam sim no thiab qhov hluav taws xob (tso tawm lub sijhawm ntawm ib lub voj voog, piv txwv li, lub sijhawm) thiab theem sib txawv (lub sijhawm) ntawm ob lub teeb liab.
4. Nruab nrog ob txoj kev ywj pheej, ob qho tib si cais los ntawm lwm cov khoom tawm ntawm chav tsev, nws tuaj yeem yooj yim ntsuas cov neeg nyob sib ze, ua tau raws li qhov yuav tsum tau ua hauv online relay test. Kev xaim yog yooj yim thiab nyab xeeb.
5. Ua haujlwm raws sijhawm siv sijhawm (10 microseconds) thiab lub txee nrog lub neej ntev txog li 100 teev, yog li nws tuaj yeem siv nws tus kheej raws li qhov tseeb millisecond timer, hloov cov tsoos stopwatch.
