(1) Li ka itilize pou mezi faz nikleyè vòltaj ba -pou mezire si nenpòt fil nan liy lan an faz oswa defaz. Metòd espesifik la se: kanpe sou yon objè izole soti nan tè a, kenbe yon plim tès nan chak men, ak Lè sa a, teste sou de fil yo dwe teste. Si de kreyon tès yo klere byen klere, de fil yo diferan. Okontrè, li se nan menm faz la, ki jije pa prensip la ke diferans vòltaj ant de poto yo nan anpoul lumineuz la nan plim tès la se pwopòsyonèl ak entansite lumineux li yo.
(2) Li ka itilize pou fè distenksyon ant kouran altènatif ak kouran dirèk. Lè w teste ak yon plim tès, si tou de poto nan anpoul lumineuz nan plim tès la klere, li se kouran altènatif; si sèlman youn nan de poto yo klere, li se kouran dirèk.
(3) Yo ka jije poto pozitif ak negatif aktyèl dirèk. Konekte plim tès la ak sikwi DC la pou teste, anpoul lumineuz ki klere se poto pozitif la, epi poto ki pa -ekleraj la se poto negatif la.
(4) It can be used to judge whether the DC is grounded. In the DC system with insulation to the ground, you can stand on the ground and use the test pen to contact the positive or negative pole of the DC system. If the neon bulb of the test pen does not light up, there is no grounding phenomenon. If the neon bulb is bright, it means that there is a grounding phenomenon, and if the neon bulb is bright, it means that the positive electrode is grounded. If it shines on the finger end, it is the negative ground. However, it must be pointed out that in a DC system with a grounding monitoring relay, this method cannot be used to determine whether the DC system is grounded.
