Important: If the meter will not be used for an extended period, remove the batteries to prevent potential corrosion and damage to the device.

4.2. Connexió del cable de prova

Connect the test leads to the appropriate input jacks based on the desired measurement. The meter's illuminated input jacks will indicate the correct ports for the selected function on the rotary dial.

• The black lead (COM) is typically connected to the common jack.
• The red lead is connected to the VΩHz jack for voltage, resistance, frequency, and diode measurements.
• For current measurements, the red lead is connected to the mA jack (for milliamps) or the 10A jack (for up to 10 amps).

5. Instruccions de funcionament

5.1. Voltage Measurement (DC/AC)

Per mesurar voltage:

1. Turn the rotary switch to the 'V' (Voltage) configuració.
2. Premeu el botó FUNC. button to toggle between DC (direct current) and AC (alternating current) voltage measurement. The display will show 'DC' or 'AC'.
3. Connect the test leads across the circuit or component to be measured.
4. El voltage reading will appear on the display.

5.2. Resistance, Continuity, and Diode Test

To measure resistance, continuity, or test diodes:

1. Turn the rotary switch to the Ω (Ohms) setting.
2. Premeu el botó FUNC. button to cycle through Resistance (Ω), Continuity (buzzer icon), and Diode Test (diode icon) modes.
3. For resistance, connect the leads across the component. For continuity, touch the leads to both ends of the circuit; a beep indicates continuity. For diode test, connect leads across the diode.

5.3. Mesura de la capacitat

Per mesurar la capacitat:

1. Turn the rotary switch to the 'F' (Farad) setting.
2. Ensure the capacitor is fully discharged before connecting the test leads to prevent damage to the meter.
3. Connect the test leads to the capacitor terminals.
4. The capacitance value will be displayed.

5.4. Mesura de la temperatura

Per mesurar la temperatura:

1. Turn the rotary switch to the °C/°F setting.
2. Insert the temperature probe into the appropriate input jacks (indicated by the illuminated ports).
3. Place the probe tip on the object or area where temperature is to be measured.
4. The temperature will be displayed in Celsius or Fahrenheit. Use the FUNC. button to switch between units if necessary.
