5.6. Durchgangsprüfung
To perform a continuity test, rotate the function dial to the 'Continuity' symbol position. Connect the test leads across the circuit or component. The meter will emit an audible beep if continuity is detected (low resistance).
Video: Demonstration of a continuity test using test leads on a wire, showing the audible beep and display reading for continuity.
5.7. Kapazitätsmessung
To measure capacitance, rotate the function dial to the 'Capacitance' symbol position. Connect the test leads across the capacitor. The display will show the capacitance value. The UT202R supports capacitance measurement up to 4mF.
Video: Demonstration of capacitance measurement on a capacitor, showing the capacitance value on the display.
5.8. Temperaturmessung
To measure temperature, rotate the function dial to the 'Temperature' symbol position. Connect a K-type thermocouple (not included) to the meter. Place the thermocouple tip on the object or area to be measured. The display will show the temperature reading. The UT202R supports temperature measurement from -40°C to 1000°C.
