• Mayeso ovomerezeka a Megger okha ndi omwe ayenera kugwiritsidwa ntchito ndi mankhwalawa.
• Mayeso onse, ma probes ndi ng'ona ziyenera kukhala mwadongosolo, zoyera, komanso zosasweka kapena zosweka. Tsimikizirani kukhulupirika kwa zoyeserera musanagwiritse ntchito.
• Chiwongolero cha mayeso a mains choperekedwa ndi chidacho chiyenera kugwiritsidwa ntchito ndi anthu ophunzitsidwa bwino komanso oyenerera. Osalumikiza zoyeserera, ma pini kapena zinthu zina ndi mapulagi atatu otsogolera chifukwa chowopsa cha electrocution ndi kuphulika kwa arc.
• Onetsetsani kuti manja amakhala kumbuyo kwa alonda a probes / clips poyesa.
• Lumikizani zowongolera zoyeserera nthawi zonse ku chida ndikutsitsa pansi chida musanadutse gawo la batri.
• Battery module iyenera kusinthidwa pamalo oyera komanso owuma.
• Osatenthetsa kapena kutaya batire pamoto. Osayika batire ku mphamvu yamphamvu, kugwedezeka kwa makina kapena kutentha kwambiri.
• Osachedwetsa kapena kubweza polarity ya batri.
• Onetsetsani kuti selo iliyonse mu module ya batri ya AA ndi yamtundu wofanana, ndikuyika mumayendedwe olondola.
  Osasakaniza ma cell omwe amatha kuchajwanso komanso osalipitsidwa.
• Chidacho chiyenera kukhazikitsidwa kuti CHODZIWA chisanakhale chokonzekera kutumiza.
• Chophimba cha fuse chomwe chili pansi pa gawo la batri chiyenera kuyikidwa bwino musanalumikizane ndi gawo la batri kapena
  chitetezo chidzasokonezedwa.
• Palibe magawo omwe angagwiritsidwe ntchito mkati mwa chida. Kupatula kutsegula chivundikiro cha fuse kuti musinthe ma fuse ndikukweza mafimuwa, musatsegule chidacho.

Machenjezo a Earth Test

Poyesa kukana kwa electrode yapadziko lapansi pomwe makina ogawa ali ndi mphamvu, machenjezo owonjezera otsatirawa amagwira ntchito.

• Anthu onse okhudzidwa ayenera kuphunzitsidwa ndi kukhala odziwa njira zodzipatula komanso chitetezo kuti dongosololi ligwiritsidwe ntchito. Ayenera kulangizidwa momveka bwino kuti asamakhudze ma electrode a padziko lapansi, ma stake oyesera, ma test lead, kapena kuthetsedwa kwawo ngati 'Live' angakumane nawo. Ndibwino kuti azivala magolovesi oyenerera a labala, nsapato za sole ya mphira, ndi kuyimirira pamphasa.
• Electrode yapadziko lapansi yomwe ikuyesedwa iyenera kukhala yotalikirana ndi dera lomwe ikutetezedwa kuyezetsa kusanayambe. Ngati izi sizingatheke, ART (yophatikizidwa ndi Rod Technique) ingagwiritsidwe ntchito kuyesa kukana kwa electrode.
