Ubukhulu Bomshini
Ukunaka
Izinzwa kufanele zithobelane namazinga e-IEC61010-1. Izinzwa kufanele zifakwe ezintweni zikagesi noma zikagesi ezihlangabezana nezindinganiso zohlelo lokusebenza nezidingo zokuphepha ngokuhambisana nemiyalelo yokusetshenziswa.
- Qaphela. Qaphela ukwethuka.
Lapho inzwa isebenza, ezinye izingxenye zingase zibe ngaphansi kwamandla ombane ayingozi (isb. ibha yebhasi eyinhloko, ukunikezwa kwamandla kagesi), futhi ukunganakwa kwalokhu kuzoholela ekulimaleni nasezingozini ezimbi kakhulu. Inzwa iyisisetshenziswa esakhelwe ngaphakathi, futhi ingxenye yayo ye-conductive kufanele iqinisekiswe ukuthi ngeke ithintwe yizwe langaphandle ngemva kokufakwa. Ikesi lokuzivikela noma ikhava eyisivikelo ingangezwa uma kunesidingo. Ukunikezwa kwamandla okuyinhloko kufanele kukwazi ukunqanyulwa.
