5.1. Ngba agbara si Batiri naa
The ANENG 681 Multimeter is equipped with a rechargeable lithium battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB Type-C cable.
- Locate the Type-C charging port on the side of the multimeter.
- Connect the Type-C cable to the multimeter and the USB-A end to a compatible USB power adapter (not included) or a computer USB port.
- Atọka gbigba agbara lori ifihan yoo fi ipo gbigba agbara han.

5.2. Agbara lori / Paa
Press and hold the power button located on the side of the multimeter to turn the device on or off.
5.3. Nsopọ Awọn itọsọna Igbeyewo
Insert the red test lead into the 'VΩHz' input jack and the black test lead into the 'COM' input jack for most voltage, resistance, and continuity measurements. For current measurements, refer to the specific operating mode section.
6. Awọn ọna ṣiṣe
The ANENG 681 features a smart mode that automatically identifies the measurement type. You can also manually select specific functions.

Image 6.1: Visual representation of the multimeter's diverse measurement capabilities.
6.1. Smart Mode (Auto)
Upon powering on, the multimeter defaults to smart mode, indicated by 'Auto' on the display. In this mode, the device automatically recognizes and measures AC/DC voltage, resistance, ati itesiwaju.

6.2. Resistance Wiwọn
In smart mode, connect the test leads across the component to measure resistance. The device will automatically display the resistance value.
6.3. Continuity Test (Buzzer)
For continuity, connect the test leads across the circuit or component. A beep indicates a good connection (low resistance), while no sound indicates an open circuit (high resistance).
6.4. DC Voltage Idiwon
Connect the red test lead to the positive terminal and the black test lead to the negative terminal of the DC source. The multimeter will display the DC voltage.
6.5. AC Voltage Idiwon
Connect the test leads across the AC source. The multimeter will display the AC voltage ati igbohunsafẹfẹ.
6.6. Iwọn Diode
For diode measurements, distinguish between positive and negative poles. Connect the red test lead to the anode and the black test lead to the cathode. The display will show the forward voltage ju.
6.7. Iwọn Iwọn otutu
Connect the temperature probe to the multimeter. Place the probe tip on the object whose temperature you wish to measure. The display can show readings in both Fahrenheit and Celsius.
6.8. Iwọn Iwọn agbara
Pataki: Before measuring capacitance, ensure the capacitor is fully discharged to avoid damage to the multimeter or personal injury due to high voltage. Connect the test leads across the discharged capacitor. The multimeter will display the capacitance value.
6.9. AC / DC Iwọn Iwọn lọwọlọwọ
To measure current, the multimeter must be connected in series with the circuit. Disconnect the loop and connect the stylus in series with both ends of the dot line to measure the current. Ensure the correct input jacks (mA A or 10A/10SEC MAX) are used based on the expected current range.
6.10. NCV (Ti kii- Olubasọrọ Voltage) Induction
Iṣẹ́ NCV gba láàyè láti rí i pé a ti lo AC vol dáadáatage without direct contact. Hold the multimeter near the suspected live wire or outlet. The device will indicate the presence of AC voltage with visual and audible alarms. The frequency of the buzzer alarm is slow for the zero line and fast for the line of fire.
