5. Configurare inițială

5.1 Încărcarea bateriei

The ANENG 623 Multimeter comes with a built-in 3.7V 1800mAh rechargeable lithium battery. Before first use, or when the battery indicator on the display shows low power, charge the device using the provided USB Type-C charging cable. Connect the cable to the multimeter's charging port and a standard USB power source (e.g., computer USB port, USB wall adapter).

5.2 Conectarea cablurilor de testare

Always ensure the multimeter is OFF before connecting or disconnecting test leads. Insert the red test lead into the appropriate positive (+) input jack (e.g., VΩmA or 10A depending on the measurement) and the black test lead into the common (COM) input jack.

5.3 Pornire/Oprire

Press the Power button (1) to turn the multimeter ON. The display will light up. To turn it OFF, press and hold the Power button again. The multimeter also features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.

This section details how to perform various measurements with your ANENG 623 Multimeter.

6.1 AC/DC Voltage Măsurare

• Press the 'V' button (5) to select AC or DC voltagModul e.
• Conectați sondele de testare în paralel cu circuitul sau componenta pe care doriți să o măsurați.
• Pentru AC voltage, the screen backlight may turn yellow for high voltage. Vol maretage Hz can be viewed after AC voltage măsurare.
• For mV DC voltage, switch to the 'mV' gear (11) and connect the test leads to the voltage sursa.

6.2 Măsurarea curentului AC/DC

• Press the 'mA/A' button (8) to select AC or DC current mode.
• Ensure the test leads are connected to the correct input jacks (VΩmA or 10A for current, and COM).
• Connect the multimeter in series with the circuit to measure current.

6.3 Resistance and Continuity Test

• Press the 'Ω' button (7) to select resistance or continuity mode.
• For resistance, connect the test leads across the component.
• For continuity, the multimeter will beep if there is a continuous path.

6.4 Măsurarea capacității

• Press the 'Capacitance/Diode' button (10) to select capacitance mode.
