Kungani isilawuli sokushisa se- Isithando somlilo ashisise?

Kuyinto evamile ukuthi isithando somlilo se-muffle sidlule izinga lokushisa elibekiwe ngama-degree angu-15-20. Phakathi nenqubo yokushisisa, i-ammeter izokwehla ifike ku-zero isikhashana bese isibonisi sizoba esivamile. Uma izinga lokushisa elibekiwe liphezulu kakhulu, lizonqamula ngokuzenzakalela lamanje ukuze liphole. Uma izinga lokushisa liphansi kunezinga lokushisa elimisiwe, uhlelo luzogcwalisa ngokuzenzakalelayo okwamanje ukuze kushise. Uma izinga lokushisa lingaphezu kuka-50 ℃, udinga ukunaka. Ngaphezu kwalokho, uma ingawi ngemuva kokushiywa amahora, kungenzeka ukuthi indawo lapho i-thermocouple ixhunywe khona isizoshisa. Kunconywa ukuyihlola.
