3. Assegureu-vos que totes les connexions siguin fermes i segures.

5. Instruccions de funcionament

This section details how to perform various measurements and utilize the multimeter's functions.

5.1 Mesures bàsiques

1. Voltage (AC/DC) Measurement:
   Gireu l'interruptor rotatiu a la posició 'V~' (Volum ACtage) or 'V-' (DC Voltage) position. Connect the test leads in parallel to the circuit or component to be measured. The reading will appear on the LCD.
2. Current (AC/DC) Measurement:
   Turn the rotary switch to the 'A~' (AC Current) or 'A-' (DC Current) position, selecting the appropriate range (µA, mA, or 20A). Connect the test leads in series with the circuit.
3. Mesura de la resistència:
   Turn the rotary switch to the 'Ω' position. Connect the test leads across the component. Ensure the circuit is de-energized before measuring resistance.
4. Mesura de la capacitat:
   Turn the rotary switch to the 'F' (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement.
5. Mesura de la temperatura:
   Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple (included) to the input terminals. The temperature will be displayed.
6. Frequency (Hz) Measurement:
   Turn the rotary switch to the 'Hz' position. Connect the test leads to the signal source.
7. Prova de díode:
   Turn the rotary switch to the 'Diode' symbol position. Connect the red lead to the anode and the black lead to the cathode of the diode. The forward voltagEs mostrarà una gota.
8. Prova de continuïtat:
   Turn the rotary switch to the 'Continuity' symbol position. Connect the test leads across the circuit or component. A buzzer will sound if continuity is detected.

5.2 Funcions especials

• RMS veritable: The OW18E features True RMS measurement, providing accurate readings for both sinusoidal and non-sinusoidal AC waveforms.
• Vol. Sense contactetagDetecció de e (NCV): Activate the NCV function to detect the presence of AC voltage without direct contact. The strength indicator will illuminate, and an audible alarm will sound if voltages detecta e.
• Il·luminació de fons: Press the backlight button to illuminate the LCD for improved visibility in low-light conditions.
• Conservació de dades: Premeu el botó «HOLD» per congelar la lectura actual a la pantalla. Torneu a prémer-lo per alliberar-lo.
