Ungahlulela kanjani ikhwalithi ye ukushisa okuphezulu kwesithando somlilo i-thermocouple?

1. Bheka ngokubukeka ukuthi ishubhu lokuvikela ligqwalile futhi liyangena yini, noma liyavuza, njll.

2. Sebenzisa i-multimeter ukukala ukuqhubeka. Ukumelana kwe-thermocouple ehlanganisiwe ngokuvamile akubi ngaphezu kwama-2 ohms, futhi ukumelana kwentambo yenethiwekhi ngokuvamile akubi ngaphezu kwama-ohms angu-50. Ngokuvamile, kunganqunywa ukuthi iphukile uma inkulu kuno-1K.

3. Linganisa inani lokumelana nge-multimeter. Uma ukumelana kudlula i-100K, kubi.

4. Sebenzisa indlela yokulinganisa ye-multimeter ohm ukuze ulinganise, ulungise ukumelana, uxhume iziphetho ezimbili, futhi uyishise ngesilula. Uma i-pointer ye-multimeter ngokusobala inkulu noma incane, kusho ukuthi inhle. Uma i-pointer inganyakazi, kusho ukuthi iphukile.

5. Sebenzisa i-multimeter ukukala i-voltage emikhawulweni yomibili ebangeni le-millivolt. Uma ingekho i-voltage, izophuka.
