Please read this manual thoroughly before use to ensure proper operation and to prevent potential hazards.

2. Informació de seguretat

Sempre observeu les següents precaucions de seguretat quan utilitzeu el multímetre:

• Doble aïllament: The multimeter features double insulation for user protection. Do not attempt to bypass or modify this safety feature.
• Categories de mesura: This device is rated CAT III 300V and CAT II 500V. Ensure that the measurement category and voltage rating are appropriate for the circuit being tested.
• Inspect Test Leads: Before each use, inspect the test leads for any damage to the insulation or exposed metal. Do not use damaged leads.
• Do Not Exceed Maximum Input Values: Refer to the specifications section for maximum input values for each function. Exceeding these limits can damage the meter and pose a safety risk.
• Protecció de fusibles: The multimeter is protected by fuses (500mA 500V Fastrapid and 10A 500V Fastrapid). If a fuse blows, replace it only with a fuse of the specified type and rating.
• Nivell de bateria: Ensure batteries are adequately charged. A low battery indicator may affect measurement accuracy.
• Condicions ambientals: Operate the multimeter within the specified operating temperature range (0°C to +40°C).
• Connexió adequada: Always connect the common (COM) test lead first, then the live test lead. Disconnect the live test lead first, then the common test lead.
• Eviteu condicions humides: Do not use the multimeter in wet or damp ambients.

5. Instruccions de funcionament

Before taking any measurements, ensure the test leads are securely plugged into the correct input jacks.

5.1 Mesurar DC Voltage (V=)

1. Introduïu el cable de prova vermell a la presa VΩmA i el cable de prova negre a la presa COM.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 500). If the voltage is unknown, start with the highest range and decrease as needed.
3. Connecteu les sondes de prova al component o circuit que s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla digital.

5.2 Mesurar AC Voltage (V~)

1. Introduïu el cable de prova vermell a la presa VΩmA i el cable de prova negre a la presa COM.
2. Set the rotary switch to the desired ACV range (e.g., 200, 500). If the voltage is unknown, start with the highest range.
3. Connecteu les sondes de prova a través del voltatge de CAtage font.
4. Llegeix el voltage valor a la pantalla digital.

5.3 Measuring DC Current (A=)

1. For currents up to 200mA: Introduïu el cable de prova vermell a la presa VΩmA i el cable de prova negre a la presa COM.
2. For currents up to 10A: Insert the red test lead into the 10A jack and the black test lead into the COM jack. Caution: Do not measure more than 10 seconds every 10 minutes when using the 10A range.
3. Set the rotary switch to the desired DCA range (e.g., 2000µ, 20m, 200m, 10A).
