Configuración
Instalación de baterías
The Fluke 301A Clamp Meter requires two AAA batteries for operation. To install or replace batteries:
- Asegúrese de que o medidor estea APAGADO.
- Localice o compartimento das baterías na parte traseira do medidor.
- Use un desaparafusador para abrir a tapa do compartimento da batería.
- Introduza dúas pilas AAA, respectando a polaridade correcta (+/-) tal como se indica no interior do compartimento.
- Coloque a tapa do compartimento da batería e fíxaa co parafuso.
The meter features an auto power-off function to conserve battery life, providing up to 500 hours of operation.
Instrucións de funcionamento
Familiarize yourself with the control knob and input terminals before operation.
Turning On/Off and Backlight
- To turn the meter ON, rotate the control knob from the OFF position to any desired measurement function.
- To turn the meter OFF, rotate the control knob to the OFF position.
- To activate the backlight, press and hold the "2s" button (often integrated with the HOLD button or a dedicated backlight button). Press and hold again to turn it off.
Medición de corrente alterna
- Rotate the control knob to the AC Current (A~) position.
- Preme o gatillo para abrir o clampmandíbula.
- Place the jaw around a single conductor (not a bundle of wires) through which the current flows. Ensure the jaw is fully closed.
- Lea o valor da corrente CA na pantalla.

Medición AC/DC Voltage
- Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
- Rotate the control knob to the AC Voltage (V~) ou Vol. CCtage (V-) position.
- Conecte as sondas de proba ao circuíto ou compoñente que se vai medir.
- Le o voltago valor da pantalla.
Medición de resistencia e continuidade
- Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
- Rotate the control knob to the Ω (Resistance) or Continuity position.
- For resistance, connect the test probes across the component. For continuity, connect the probes across the circuit.
- Read the resistance value or listen for the audible tone for continuity.
Proba de diodos
- Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
- Rotate the control knob to the Diode (->|) position.
- Conecta a sonda vermella ao ánodo e a sonda negra ao cátodo do díodo.
- Ler o voltage drop on the display. Reverse the probes to check for open circuit.

Measuring Frequency and Capacitance
- Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
- Rotate the control knob to the Hz (Frequency) or F (Capacitance) position.
- Conecte as sondas de proba a través do circuíto ou compoñente.
- Read the frequency or capacitance value on the display.
Función de retención de datos
Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold and resume live readings. This is useful for recording measurements in difficult-to-view localizacións.
