Voltage tester ke sesebelisoa sa bohlokoa sa tlhahlobo lits'ebetsong tsa motlakase, se sebelisetsoang ho lekanya maemo a motlakase lipotolohong le ho netefatsa ts'ebetso e bolokehileng ea lisebelisoa tsa motlakase. Ho netefatsa litekanyo tse nepahetseng, e tlameha ho lekanyetsoa le ho netefatsoa ho latela mekhoa e tloaelehileng ea tlhahlobo. Se latelang ke ts'ebetso e felletseng ea tlhahlobo ea voltage tester.
1.Pele{1}}Boitokiso ba Teko
Pele o qala tlhahlobo, etsa bonnete ba hore maemo a latelang a fihlelleha:
• Litlhoko tsa Tikoloho: Tikoloho ea tlhahlobo e lokela ho ba e ommeng le ho se be le tšitiso e matla ea makenete ea motlakase, ka mocheso o laoloang pakeng tsa 10 le 30 degrees le mongobo o sa feteng 80% RH.
• Boemo ba Lisebelisoa: Sehlahlobi sa motlakase se tlas'a teko se lokela ho ba boemong bo botle, se se na tšenyo kapa likarolo tse hlephileng, 'me se be le tefiso e lekaneng ea betri (ha ho hlokahala).
• Thepa e Tloaelehileng: Lokisetsa-mohloli o nepahetseng oa motlakase oa maemo a holimo (joaloka voltmeter kapa calibrator) o nepahetseng ka makhetlo a 3-5 ho feta oa sesebelisoa se ntseng se lekoa ho netefatsa liphetho tse tšepahalang tsa liteko.
• Mehato ea Tšireletseho: Basebelisi ba lokela ho roala liatlana tse sireletsang tšireletso, ho etsa bonnete ba hore tikoloho ea teko ha e na likotsi tse ngata tsa motlakase, le ho ntša motlakase o sa hlokahaleng oa potoloho tlas'a teko.
2. Ponahalo le Tlhahlobo ea Ts'ebetso
Pele ho tlhahlobo e hlophisitsoeng, etsa tlhahlobo ea mantlha:
• Tlhahlobo ea Ponahalo: Netefatsa hore ponts'o e hlakile ebile ha ea senyeha, likonopo lia arabela, 'me li-terminal ha li na oxidation kapa ho hlehla.
• Teko ea Tšebetso: Ka mor'a ho kenya motlakase ho tester ea motlakase, hlahloba hore na e phahama ka tsela e nepahetseng, e fetoha hantle pakeng tsa mekhahlelo, 'me ha e bontše ho thothomela ho sa tloaelehang kapa likhoutu tsa liphoso.
3. Zero le Tekanyetso-Sekala se Feletseng
• Zero Calibration: Ha ho na motlakase o kenang (kapa o kenyang haufi le 0V), lokisa konopo ea zero ea sesebelisoa (haeba e na le lisebelisoa) hore ponts'o e bale 0.00V kapa e haufi le zero.
• Feletseng-Scale calibration: Kenya lebelo le phahameng ka ho fetisisa la mohlodi wa motlakase o tlwaelehileng (mohlala, 100V, 500V, kapa hodimo, ho itshetlehile ka mofuta wa molekodi) mme o lokise konopo ya ho lekanya sesebediswa hore boleng bo hlahang bo tsamaellane le boleng bo tlwaelehileng, mme phoso e ka tlase ho ±0.5% ho isa ho 1%.
4. Teko ea ho Nepaha
• Teko ea-ea mefuta e mengata: Kenya boleng bo tloaelehileng ba voltage karolong e 'ngoe le e 'ngoe ea voltage tester (mohlala, 2V, 20V, 200V, 1000V), rekota boleng bo bontšitsoeng ba moleko, o bapise le boleng bo tloaelehileng, 'me u bale phoso.
• Palo ea Phoso: Phoso=(Boleng bo Lekanyelitsoeng - Boleng bo Tloaelehileng) / Boleng bo Tloaelehileng × 100%. Netefatsa hore phoso ea mofuta o mong le o mong e kopana le lintlha tsa tekheniki tsa sesebelisoa (hangata e hloka ±1% ho isa ho ±3%).
• Tlhahlobo ea Linearity: Lekola li-voltage tse ngata tse mahareng (mohlala, 50V, 250V, 500V) ho bona hore na boleng bo lekantsoeng bo fetoha ka mokhoa o ikhethileng ho qoba liphoso tse sa tloaelehang.
5. Teko ea Botsitso le Pheta-pheta
• Teko ea Botsitso: Ka matla a motlakase a tsitsitseng (mohlala, 100V), hlokomela hore na 'malo oa voltage tester' o tsamaea metsotso e 5-10. Tlas'a maemo a tloaelehileng, phetoho e lokela ho ba tlase ho ± 0.1%.
• Teko ea ho Pheta-pheta: Lekanya boleng bo tšoanang ba motlakase ka makhetlo a mangata (mohlala, makhetlo a 5-10) 'me u bale ho kheloha ho tloaelehileng ha lipalo ho netefatsa hore phoso ea ho pheta-pheta e ka har'a sebaka se amohelehang.
6. Tlhahlobo ea Sephetho sa Tlhahlobo le ho Rekota
• Litekanyetso tsa Kamohelo: Haeba phoso, botsitso, le ho pheta-pheta ha mefuta eohle li kopana le lintlha tsa tekheniki tsa moetsi, sehlahlobi sa motlakase se nkoa se fetile tlhahlobo.
• Ho hloleha ho sebetsana le bothata: Haeba phoso e feta tekanyo e amohelehang, ho hlokahala hore ho lokisoe kapa ho lokisoe, 'me karolo e nang le phoso e tlameha ho nkeloa sebaka ha ho hlokahala.
• Ho Boloka Litlaleho tsa Litlaleho: Lirekoto tse qaqileng tsa letsatsi la teko, maemo a tikoloho, tlhahisoleseding e tloaelehileng ea lisebelisoa, lintlha tsa litekanyo, le liqeto tsa ho qetela li bolokiloe bakeng sa ho lateloa habonolo.
7. Phahamisa{1}}Mekhoa ea Teko
• Khutlisa Litlhophiso: Khutlisa sehlahlobi sa voltage ho li-setting tsa kamehla tsa feme kapa mekhahlelo e sebelisoang khafetsa ea mosebelisi ho netefatsa tšebeliso e bonolo.
• Ho Hloekisa le ho Boloka: Hlakola bokaholimo ba sesebelisoa ka lesela le bonolo ebe u boloka sebakeng se omileng, se lefifi ho thibela mocheso o phahameng le mongobo hore o se ke oa ama ho nepahala.
Ka mor'a mekhoa ena e tloaelehileng, ho ka netefatsoa ho nepahala ha tekanyo ea "voltage tester", ho sireletsa ts'ebetso e bolokehileng ea sistimi ea motlakase. Teko ea kamehla (e khothalletsoang likhoeli tse ling le tse ling tse tšeletseng ho isa ho selemo se le seng) ke mohato oa bohlokoa oa ho boloka botšepehi ba lisebelisoa.
