5. Instruccions de funcionament
Always ensure the multimeter is set to the correct function and range before making any measurements. Refer to the LCD Display Analysis section for symbol meanings.
5.1. General Measurements
- DC Voltage Mesura: Switch to the DCV range. Connect the test leads to the positive and negative terminals of the circuit or component. The display will show the DC voltage.
- Vol. ACtage Mesura: Switch to the ACV range. Connect the test leads to the circuit. The display will show the AC voltage i freqüència.
- Mesura de la resistència: Switch to the Ω (Resistance) range. Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
- Mesura de la capacitat: Switch to the capacitance range. Important: Discharge the capacitor completely before measurement to avoid damage to the multimeter. Connecteu els cables de prova a través del condensador.
- Prova de díode: Switch to the diode test function. Connect the red test lead to the anode and the black test lead to the cathode of the diode. The display will show the forward voltagcaiguda electrònica. Invertiu els cables per comprovar si hi ha un circuit obert.
- Prova de continuïtat: Switch to the continuity function (buzzer icon). Connect the test leads across the circuit or component. A beep indicates continuity (low resistance).
- Frequency (Hz) Measurement: Switch to the Hz range. Connect the test leads to the signal source. The display will show the frequency.
- Mesura de la temperatura: Connect the temperature probe to the multimeter. Switch to the °C or °F temperature range. Place the probe tip on the object whose temperature you wish to measure.

5.2. Current Measurement (DC/AC)
WARNING: Current measurements MUST be performed with the multimeter connected IN SERIES with the circuit. NEVER connect the multimeter in parallel for current measurement, as this will damage the instrument.
Figure 5.2: Correct Current Measurement Connection (Series)
- Mesura de corrent DC: Switch to the DCA or mA DCA range. Insert the red test lead into the 10A or mA input jack and the black test lead into the COM jack. Break the circuit and connect the multimeter in series.
- Mesura de corrent CA: Switch to the ACA or mA ACA range. Insert the red test lead into the 10A or mA input jack and the black test lead into the COM jack. Break the circuit and connect the multimeter in series.
5.3. Vol sense contactetage (NCV) Detecció
La funció NCV permet la detecció sense contacte del volum de CA.tage, useful for identifying live wires without direct contact.
- Switch the multimeter to the NCV function.
- Move the multimeter's NCV sensing area (usually the top edge) near the suspected AC voltage font.
- Si AC voltage is detected, the display will show 'EF', a buzzer will sound, and the LCD analog bar will indicate the induction intensity.
Figura 5.3: Detecció de NCV
5.4. Live Wire Identification
This function helps distinguish between live and neutral wires.
- Switch the multimeter to the 'Live' function.
- Use the red test lead to touch the wire.
- If it's a live wire, the multimeter will beep and show a 'Live' indication. If it's a neutral wire, there will be no response.
Figure 5.4: Live Wire Identification
5.5. Automotive Measurements
- Engine Speed (RPM) Test:
- Select the appropriate engine stroke (e.g., 2-stroke, 4-stroke).
- Connect the black test lead to a good ground terminal of the car battery.
- If the car uses a DIS (Distributorless Ignition System), connect the red test lead to the TACH (tachometer) signal line.
- If the car uses a distributor ignition system, connect the red test lead to the negative end of the ignition coil primary.
- Start or run the engine and read the RPM value from the display.
- Engine Dwell Angle Measurement:
- This measures the closure angle of the open circuit switch of the ignition system.
- Connect the red test lead to the negative end of the ignition coil primary.
- Select the appropriate number of cylinders for measurement.
- Start or run the engine and read the dwell angle from the display.
- Car Pulse Width (mS-PULSE) Measurement:
- Switch to the 'PULSE' gear.
- Connect the black test lead to the car's ground terminal.
- Connect the red test lead to the electromagnetic drive input line of the fuel injector.
- Start the engine and measure the pulse width time.

6. Manteniment
- Apagat automàtic: The multimeter will automatically shut down after 15 minutes of no operation to conserve battery life.
- Indicació de bateria baixa: A low battery icon will appear on the display when the battery needs charging.
- Neteja: Utilitzeu un suau, damp cloth to clean the multimeter's casing. No utilitzeu productes de neteja abrasius ni dissolvents.
- Emmagatzematge: Store the multimeter in its protective bag in a dry, cool place away from direct sunlight and extreme temperatures.
7. Solució De Problemes
7.1. Multimeter Displaying Non-Zero in mV Range
If the multimeter shows a non-zero reading in the mV range even when no voltage is applied, this can be due to:
- Excessive changes in ambient temperature and humidity in the air.
- Strong electric field or magnetic field interference.
Solució: To confirm if this is the case, short circuit the red and black test leads. The multimeter should display "0000". This non-zero phenomenon is due to environmental factors and does not affect the use of the multimeter. However, it is recommended to eliminate environmental interference factors to ensure measurement accuracy and prevent erroneous results.
