2. Informació de seguretat
Always adhere to safety precautions when using the multimeter to prevent electric shock or damage to the instrument. Read all safety information before use.
Pautes generals de seguretat:
- No utilitzeu el mesurador si sembla danyat o si els cables de prova estan danyats.
- No apliqueu més del volum nominaltage, tal com està marcat al comptador, entre terminals o entre qualsevol terminal i terra.
- Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
- Desconnecteu sempre l'alimentació del circuit i descarregueu totes les emissions d'alt volum.tage capacitors before testing resistance or capacitance.
- Assegureu-vos que s'hagin seleccionat la funció i el rang correctes abans de fer mesures.
- No feu servir el mesurador al voltant de gas, vapor o pols explosius.
- The meter is rated for CAT III 600V and CAT II 1000V. Ensure your application falls within these safety categories.

6. Instruccions de funcionament
The FLUKE 18B+ operates in Manual Range mode. Select the desired function using the rotary dial.
6.1. Mesura de vol AC/DCtage (V)
- Gireu el selector rotatiu a la posició 'V~' (Volum ACtage) or 'V-' (DC Voltage) posició.
- Connecteu els cables de prova en paral·lel al circuit o component que voleu mesurar.
- Llegeix el voltage valor a la pantalla.
6.2. Mesura de la resistència (Ω)
- Turn the rotary dial to the 'Ω' (Resistance) position.
- Assegureu-vos que el circuit estigui desenergitzat i que tots els condensadors estiguin descarregats.
- Connecteu els cables de prova a través del component per mesurar-ne la resistència.
- Llegiu el valor de resistència a la pantalla.
6.3. Measuring AC/DC Current (A)
- Turn the rotary dial to the 'A~' (AC Current) or 'A-' (DC Current) position, selecting the appropriate range (mA/µA or 10A).
- Assegureu-vos que el circuit estigui desenergitzat.
- Connecteu el multímetre en sèrie amb el circuit.
- Aplica energia al circuit.
- Llegiu el valor actual a la pantalla.
6.4. Measuring Capacitance (nF/µF)
- Turn the rotary dial to the 'nF' (Capacitance) position.
- Assegureu-vos que el condensador estigui completament descarregat abans de connectar els cables de prova.
- Connecteu els cables de prova a través del condensador.
- Llegiu el valor de la capacitat a la pantalla.
6.5. Prova LED
- Turn the rotary dial to the 'LED TEST' position.
- Connect the test leads to the LED, observing polarity.
- The multimeter will display the forward voltage (Vf) of the LED.
6.6. Prova de díode i continuïtat
- Turn the rotary dial to the 'Diode/Continuity' position.
- For Diode Test: Connect the test leads across the diode. The display will show the forward voltagcaiguda electrònica. Invertiu els cables per comprovar si hi ha un circuit obert.
- For Continuity Test: Connect the test leads across the circuit. An audible buzz indicates continuity.
6.7. Funció HOLD
Press the 'HOLD' button to freeze the current reading on the display. Press it again to release and resume live readings.
6.8. Llum de fons
