(1) Anvan ou sèvi ak plim tès la, premye tcheke si gen yon rezistans sekirite nan plim tès la, ak Lè sa a, vizyèlman tcheke si plim tès la domaje, si li mouye oswa dlo, epi li ka sèlman itilize apre yo fin pase enspeksyon an.
(Principle: There is a resistance in the test pen, and there is a light-emitting body - a neon tube. The key lies in the neon tube. After the resistance is reduced, there is a voltage to one end of the neon tube, forming a high potential. Your hand needs to touch the metal at the end of the pen. end, now you are the ground wire. There are two thin metal wires in the neon tube, which are very close to each other, but they are not connected. The neon tube is naturally filled with neon gas. Light discharge. If the voltage is too large, the neon tube will be broken down instantly. At this time, the neon tube will act as an insurance and will not cause too much damage to you. Low voltage will be more dangerous, because the traditional electric pen, the neon tube electric pen, operates at 100V. It will only light up from the left and right, so don't be careless, and don't let the electric pen get into the water, otherwise you will know the feeling of electric shock.)
(2) Lè w ap itilize plim tès la, pa manyen sond metal la devan plim tès la ak men w, paske si w fè sa ap lakòz yon aksidan chòk elektrik.
(3) Lè w ap itilize plim tès la, asire w ke ou manyen pati metal la nan fen plim tès la ak men ou, otreman, paske kò a chaje, plim tès la, kò imen an ak tè a pa fòme yon kous, ti wonn lumineuz nan plim tès la pa pral emèt limyè, sa ki lakòz move jijman. Li trè danjere pou panse ke yon kò chaje pa chaje.
(The luminous voltage of the neon tube is above 70V, and the series resistance is 500K. When testing the voltage of 220V, the maximum current flowing through the human body is: I=(220-70)÷500=0.3mA and the human body only passes the current of 1mA. Feeling numb.)
(4) Anvan ou mezire si ekipman elektrik la chaje, premye jwenn yon sous pouvwa li te ye pou teste si anpoul lumineuz plim elektrik la ka emèt limyè nòmalman, epi li ka itilize nòmalman.
(5) When testing a charged body under bright light, special attention should be paid to whether the neon bulb really glows (or does not glow), and if necessary, the other hand can be used to block the light to judge carefully. Don't make a misjudgment, judge that the neon bulb is not emitting light, and judge that there is electricity as no electricity.
