5.1 Charging the Multimeter

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. Plug the other end of the cable into a standard USB power adapter (not included) or a computer's USB port.
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 Connexió dels cables de prova

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. Instruccions de funcionament

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.
