1. Informació important de seguretat

Please read and understand all safety information and operating instructions before using this device. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Always adhere to the specified measurement category (CAT III 600V) and voltage/current limits.
• No utilitzeu el multímetre si sembla que està danyat o si els cables de prova estan compromesos.
• Ensure test leads are correctly inserted into the appropriate input jacks for the desired measurement. The device features an acoustic alarm for incorrect lead connection.
• Avoid contact with live circuits. Always assume circuits are live until proven otherwise.
• Canvieu les piles immediatament quan aparegui l'indicador de bateria baixa per garantir lectures precises.
• Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC, ja que representen un perill de descàrrega elèctrica.

3.2 Instal·lació de la bateria

The VC276 is battery-powered. To install or replace batteries:

1. Assegureu-vos que el multímetre estigui APAGAT.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior del dispositiu.
3. Descargoleu el(s) cargol(s) de subjecció i traieu la coberta.
4. Insert new batteries, observing correct polarity (+/-).
5. Torneu a col·locar la tapa del compartiment de la bateria i fixeu-la amb el(s) cargol(s).

3.3 Connexió dels cables de prova

Always connect the test leads correctly for the desired measurement function to prevent damage to the device or injury.

• Introduïu el cable de prova negre al COM (common) jack.
• Per al voltage, resistance, frequency, capacitance, and diode measurements, insert the red test lead into the VΩHz jack.
• For current measurements up to 400mA, insert the red test lead into the mAµA jack.
• For current measurements up to 10A, insert the red test lead into the 10A MÀX jack.
• The multimeter will emit an acoustic alarm if the test leads are incorrectly inserted for the selected function.

4. Instruccions de funcionament

This section details how to use the VOLTCRAFT VC276 for various measurements.

4.1 Engegada/Apagada i Selecció de Funcions

• Turn the rotary dial from the "OFF" position to the desired measurement function to power on the device.
• To power off, turn the rotary dial back to the "OFF" position.
• Use the "SELECT" button to cycle through different measurement modes within a single rotary dial position (e.g., AC/DC voltage, díode/continuïtat).

4.2 voltagMesura (CA/CC)

1. Set the rotary dial to the "V" position.
2. Connecteu el cable negre a COM i el cable vermell a VΩHz.
3. Use the "SELECT" button to choose between AC (~) or DC (---) voltage.
4. Connect the test probes in parallel to the circuit or component to be measured.
5. Llegeix el voltage valor a la pantalla.

4.3 Mesura de corrent (CA/CC)

1. Set the rotary dial to the "mAµA" or "A" position depending on the expected current.
2. Connecteu el cable negre a COM i el cable vermell a mAµA or 10A MÀX en conseqüència.
3. Use the "SELECT" button to choose between AC (~) or DC (---) current.
4. Important: Connect the test probes in series with the circuit. Never connect in parallel for current measurement.
5. Llegiu el valor actual a la pantalla.

4.4 Mesura de la Resistència

1. Ajusteu el selector rotatiu a la posició "Ω".
2. Connecteu el cable negre a COM i el cable vermell a VΩHz.
3. Assegureu-vos que el circuit o component estigui desenergitzat abans de mesurar la resistència.
4. Connecteu les sondes de prova a través del component.
5. Llegiu el valor de resistència a la pantalla.

4.5 Altres funcions

• Frequency (Hz) / Capacitance (F): Select the appropriate position on the rotary dial and use the "SELECT" button to toggle.
• Temperatura (°C/°F): Connect the temperature probe to the appropriate jacks (usually VΩHz and COM) and select the temperature function.
• Vol. Sense contactetage (NCV): Select the NCV function. Hold the top of the multimeter near an AC voltagla font per detectar la seva presència sense contacte directe.
• REL/HOLD: The "REL" (Relative) button allows you to zero out a measurement, useful for comparing values. The "HOLD" button freezes the current reading on the display.
• Low Impedance (LoZ): Press the LoZ button (if available) to temporarily reduce the input impedance, which helps in identifying and eliminating ghost voltages.
