5.1 Carga do multímetro

The ANENG 621A comes with a built-in rechargeable lithium battery. To charge the device:

1. Connect the provided Type-C charging cable to the multimeter's charging port.
2. Conecta o outro extremo do cable a un adaptador de corrente USB estándar (non incluído) ou a un porto USB dun ordenador.
3. The battery indicator on the display will show charging status. Charge until the battery icon indicates full charge.

Figure 6: Charging via Type-C.

5.2 Conexión dos cables de proba

For most measurements, connect the red test lead to the "VΩmA" input jack and the black test lead to the "COM" input jack. For high current measurements (10A), connect the red lead to the "10A" input jack.

6. Instrucións de funcionamento

The ANENG 621A features an intelligent mode (AUTO) that automatically detects the measurement type. You can also manually select functions using the touch screen buttons.

Figure 7: Functional Measurement Overview.

6.1 Smart Mode (AUTO)

When powered on, the multimeter defaults to AUTO mode. In this mode, it automatically identifies and measures AC/DC voltage, resistance, and continuity. Simply connect the test leads to the circuit, and the meter will display the appropriate reading.

6.2 Manual Function Selection

Preme o SEL button on the touch screen to cycle through different measurement functions if you need to select a specific mode not automatically detected by AUTO mode.

6.3 voltagMedición (CA/CC)

1. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
2. Seleccione AC ou DC voltage mode (or use AUTO).
3. Conecte as sondas de proba en paralelo ao circuíto ou compoñente que desexe medir.
4. Le o voltago valor da pantalla.

6.4 Medición de resistencia

1. Ensure the circuit is de-energized and capacitors are discharged.
2. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
3. Select resistance mode (or use AUTO).
4. Conecte as sondas de proba a través do compoñente.
5. Lea o valor de resistencia na pantalla.

6.5 Proba de continuidade

1. Asegúrate de que o circuíto estea desenergizado.
2. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
3. Select continuity mode (or use AUTO).
4. Touch the probes to the two points of the circuit. A beep indicates continuity.

6.6 Proba de diodo
