5.2. Encès / apagat
Press and hold the power button located on the side of the multimeter to turn the device on or off.
5.3. Connexió dels cables de prova
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. Modes de funcionament
The ANENG 681 features a smart mode that automatically identifies the measurement type. You can also manually select specific functions.

6.2. Mesura de Resistències
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 Mesura
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 Mesura
Connect the test leads across the AC source. The multimeter will display the AC voltage i freqüència.
6.6. Mesura de díodes
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 gota.
6.7. Mesura de la temperatura
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. Mesura de la capacitat
Important: 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. Mesura de corrent AC/DC
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 (No-Contact Voltage) Induction
La funció NCV permet la detecció segura del volum de CAtage 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.
