4.2 Connexió dels cables de prova

Always connect the black test lead to the 'COM' (common) input jack. Connect the red test lead to the appropriate input jack based on the measurement type:

• Per al voltage (V), Resistance (Ω), Continuity, Diode, Capacitance, and Temperature (°C/°F) measurements, connect the red lead to the 'VΩ)))°C' jack.
• The UT123T does not measure current directly via test leads.

5. Instruccions de funcionament

Turn the rotary switch to the desired function. The multimeter will automatically select the range (Auto Range) for most measurements.

5.1 voltagMesura (CA/CC)

1. Connect the black test lead to 'COM' and the red test lead to 'VΩ)))°C'.
2. Turn the rotary switch to 'V~' for AC voltage o 'V=' per a vol DCtage.
3. Toqueu les sondes de prova als punts del circuit on el volumtage s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla.

5.2 Mesura de resistència (Ω)

1. Connect the black test lead to 'COM' and the red test lead to 'VΩ)))°C'.
2. Turn the rotary switch to 'Ω'.
3. Assegureu-vos que el circuit o component estigui desenergitzat abans de mesurar la resistència.
4. Toqueu les sondes de prova a través del component.
5. Llegiu el valor de resistència a la pantalla.

5.3 Prova de continuïtat

1. Connect the black test lead to 'COM' and the red test lead to 'VΩ)))°C'.
2. Turn the rotary switch to ')))'.
3. Assegureu-vos que el circuit o component estigui desenergitzat.
4. Touch the test probes across the circuit or component. An audible beep indicates continuity.

5.4 Mesura de temperatura (°C/°F)

1. Connect the thermocouple to the 'VΩ)))°C' and 'COM' jacks, observing polarity.
2. Turn the rotary switch to '°C°F'.
3. Place the thermocouple tip on the object whose temperature is to be measured.
4. Read the temperature on the display. Use the 'SELECT' button to switch between Celsius and Fahrenheit.

5.5 Vol. sense contactetage (NCV) Detecció

1. Turn the rotary switch to 'NCV'.
2. Move the top part of the multimeter near the conductor or electrical outlet.
3. The NCV indicator light and an audible beep will activate if AC voltage is detected. The frequency of beeps and light flashes increases with stronger voltage.

It covers auto-ranging, overload protection, non-contact voltage detection, probe holder functionality, and various measurement modes including voltage, current, resistance, capacitance, diode test, and continuity.

6. Manteniment

6.1 Atenció general

• Keep the multimeter clean and dry. Use a soft, damp cloth for cleaning; do not use abrasives or solvents.
• Guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
• Avoid dropping the multimeter or subjecting it to strong impacts.

6.2 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate measurements. Follow the battery installation steps in Section 4.1.

7. Solució De Problemes

• Sense pantalla/Pantalla tènue: Check battery installation and replace if necessary. Ensure the multimeter is turned ON.
• Lectures incorrectes: Verify test lead connections. Ensure the correct function is selected on the rotary switch. Check if the batteries are low.
• 'OL' a la pantalla: This indicates an overload or out-of-range measurement. Select a higher range (if manual ranging is available, though UT123T is auto-ranging) or ensure the measured value is within the device's specifications.
• Sense bip de continuïtat: Ensure the circuit is de-energized. Check for actual continuity in the circuit.
