Ua tsaug rau cov neeg siv khoom tawm tswv yim ntawm GVDA GD110A Voltage Detector Tsis-hu Voltage Tester:
Kuv xav tias tus ntsuas hluav taws xob yog qhov "yuav tsum muaj" cov cuab yeej kev nyab xeeb rau txhua tus tswv tsev. Kom paub meej, yog tias koj yog DIYer loj rewiring chav tsev, los yog ntxiv ib qho kev hloov los yog Circuit Court, nws yog ib qho tsim nyog. Koj yeej xav tau qhov no hauv koj lub thawv khoom siv hluav taws xob. Tab sis yuav ua li cas yog tias koj tsuas yog xav paub seb lub qhov hluav taws xob lossis hluav taws xob raug kaw lossis qhib, kub lossis benign? Tej zaum koj yuav xav paub meej tias lub roj teeb polarity. Los yog koj yuav lub teeb ntawm lub chaw nres tsheb muag, ntsaws rau hauv, thiab nws tsis ua haujlwm.… puas yog lub qhov hluav taws xob ntawm phab ntsa (tej zaum muab tua ntawm lub qhov hluav taws xob?), lub teeb lub ntsaws, yog cov hlua tawg sab hauv, lossis tsuas yog qhov phem? noob?

Qhov zoo tshaj plaws GVDA Voltage tester tam sim no yog kuv lub cuab yeej tseem ceeb.
