6.1 Measurement Functions:
- AC/DC Voltage Measurement: The multimeter automatically detects AC or DC voltage. Connect the test leads across the circuit or component to measure voltage. The display will show the measured value.
- Resistance Measurement: To measure resistance, ensure the circuit is de-energized. Connect the test leads across the resistor or component. The multimeter will display the resistance value in Ohms (Ω).
- Continuity Test: For continuity, the multimeter will emit an audible beep if the resistance is below a certain threshold, indicating a continuous path.
- Diode Test: Use this function to test diodes. The multimeter will display the forward voltage drop of the diode.
- Non-Contact Voltage (NCV) Detection: Hold the tip of the multimeter near an AC voltage source without direct contact. The device will indicate the presence of voltage through an audible alarm and visual indicator.
- Live Wire Detection: Insert the red probe into the live wire. The multimeter will indicate if the wire is live.

6.2 Additional Functions:
- Flashlight: Press the dedicated flashlight button to illuminate the work area. This is particularly useful in dark environments.
- Data Hold: Press the HOLD button to freeze the current reading on the display. Press it again to release.
- Auto Power Off: The multimeter will automatically power off after approximately 5 minutes of inactivity to conserve battery life.
