5. Configuración

5.1. Instalación de la batería

The Fluke 77-4 is powered by a 9V battery. To install or replace the battery:

1. Asegúrese de que el multímetro esté apagado.
2. Localice la tapa del compartimiento de la batería en la parte posterior del multímetro.
3. Utilice un destornillador para aflojar los tornillos que sujetan la cubierta.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Vuelva a colocar la cubierta y apriete el/los tornillo(s).

5.2. Conexión de los cables de prueba

Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate input jack for your measurement:

• VΩ Hz: Por voltage, resistance, continuity, diode, and frequency measurements.
• mamá: Para mediciones de corriente de hasta 400 mA.
• 10A: Para mediciones de corriente hasta 10A.

6. Instrucciones de funcionamiento

Before taking any measurement, ensure the test leads are correctly connected and the function dial is set to the appropriate position.

6.1. Medición del volumen de CA/CCtage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagmi).
2. Conecte el cable de prueba negro al conector COM y el cable de prueba rojo al conector VΩHz.
3. Toque las sondas de prueba en los puntos del circuito donde el voltajetage debe medirse.
4. Leer el vol.tage valor en la pantalla.

6.2. Medición de resistencia (ohmios)

1. Asegúrese de que el circuito esté desenergizado antes de medir la resistencia.
2. Gire el dial giratorio a Ω.
3. Conecte el cable de prueba negro al conector COM y el cable de prueba rojo al conector VΩHz.
4. Touch the test probes across the component or circuit segment.
5. Lea el valor de resistencia en la pantalla.

6.3. Measuring Current (Amperes)

Precaución: Current measurements require breaking the circuit and inserting the multimeter in series. Incorrect connection can blow the fuse or damage the meter.

1. Desenergice el circuito.
2. Determine the expected current range. For currents up to 400mA, turn the dial to mA and connect the red lead to the mA jack. For currents up to 10A, turn the dial to A and connect the red lead to the 10A jack.
3. Conecte el cable de prueba negro al conector COM.
4. Rompa el circuito y conecte las sondas de prueba en serie con la carga.
5. Vuelva a energizar el circuito y lea el valor actual.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• MANTENER: Pulse el botón HOLD para congelar la lectura actual en la pantalla. Pulse de nuevo para liberarla.
• MINMAX: Press the MINMAX button to activate recording. The meter will display the maximum, minimum, and average readings sequentially. Press again to cycle through Min, Max, Avg. Hold the button to exit.
• GAMA: In auto-ranging modes, the meter automatically selects the best range. Press RANGE to switch to manual ranging. Each subsequent press will cycle through available ranges. Hold the button to return to auto-ranging.
