2. Información de seguridade
To ensure safe operation and prevent electric shock or personal injury, always adhere to the following safety guidelines:
- Lea e comprenda todas as instrucións antes de usar o medidor.
- Non empregue o medidor se parece estar danado ou se os cables de proba están danados.
- Verify the meter's operation on a known voltage fonte antes do uso.
- Cumprir os códigos de seguridade locais e nacionais.
- Always use the meter within its specified measurement categories and voltage/current limits. The Fluke 302+ has a CAT IV 300 V / CAT III 600 V safety rating.
- Wear appropriate personal protective equipment (PPE), such as safety glasses and insulated gloves, when working with electrical circuits.
- Non aplique máis que o voltage, tal como está marcado no contador, entre os bornes ou entre calquera terminal e terra.
- Teña coidado ao traballar con voltagpor riba de 30 V CA RMS, 42 V pico ou 60 V CC. Estes voltagsupoñen un perigo de descarga.
- Remove test leads from the meter before opening the battery compartment.

4. Configuración
4.1. Instalación da batería
The Fluke 302+ requires two AA batteries for operation. These are typically included. If batteries need replacement or initial installation:
- Asegúrese de que o medidor estea APAGADO.
- Localice a tapa do compartimento das baterías na parte traseira do medidor.
- Use a screwdriver to loosen the screw securing the cover.
- Remove the cover and insert the two AA batteries, observing correct polarity (+ and -).
- Volva colocar a tapa do compartimento da batería e aperte o parafuso firmemente.
4.2. Conexión dos cables de proba
Para o voltage, resistance, continuity, and capacitance measurements, connect the test leads as follows:
- Insira o cable de proba negro na toma de entrada COM (común).
- Insert the red test lead into the VΩCAP input jack.
5. Instrucións de funcionamento
The Fluke 302+ features a rotary dial to select measurement functions. Always ensure the meter is set to the correct function before making a measurement.
5.1. AC Current Measurement (Clamp)
To measure AC current up to 400 A using the clamp mandíbula:
- Xire o disco rotativo cara a ∽A (AC Current) position.
- Abre o clamp jaw by pressing the lever.
- Rodear só un condutor co clamp mandíbula. Asegúrate de que a mandíbula estea completamente pechada.
- Lea o valor da corrente CA na pantalla.

5.2. AC/DC Voltage Medición
Para medir AC o DC voltage up to 600 V:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o disco rotativo cara a V∽ (Volumen da CA)tage) ou V— (DC Voltage) posición.
- Touch the test probes to the test points of the circuit.
- Le o voltago valor da pantalla.
5.3. Medición da resistencia
Para medir a resistencia:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o disco rotativo cara a Ω Posición (de resistencia).
- Asegúrese de que o circuíto baixo proba estea desenergizado.
- Touch the test probes across the component or circuit to be measured.
- Lea o valor de resistencia na pantalla.
5.4. Medición de continuidade
To check for circuit continuity:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o disco rotativo cara a Ω (Resistance) position and press the 'HOLD' button to cycle to continuity mode (indicated by a speaker icon).
- Asegúrese de que o circuíto baixo proba estea desenergizado.
- Touch the test probes across the circuit or component.
- The meter will beep if continuity is detected (low resistance).
5.5. Medición de capacitancia
Para medir a capacidade:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o disco rotativo cara a CAP Posición (de capacitancia).
- Asegúrese de que o condensador estea completamente descargado antes da medición.
- Toque as puntas de proba cos terminais do condensador.
- Lea o valor da capacidade na pantalla.
5.6. Función de retención de datos
Preme o ATENCIÓN botón para conxelar a lectura actual na pantalla. Próbeo de novo para desactivar a función de retención.
5.7. Luz de fondo
Press the backlight button (indicated by a light bulb icon) to illuminate the display for better visibility in low-light conditions. Press it again to turn off the backlight.
6. Mantemento
6.1. Atención xeral
Keep the meter dry. If it gets wet, wipe it dry. Keep the meter away from dust and dirt. Wipe the meter with a damp cloth periodically. Do not use harsh chemicals, cleaning solvents, or strong detergents.
