6. Setup and Initial Use
6.1 Battery Installation
- Locate the battery compartment cover on the back of the multimeter.
- Open the cover.
- Insert one 1.5V AAA battery, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
6.2 Attaching Test Leads
- Insert the black test lead into the negative jack on the multimeter.
- Attach the red test lead tip (with or without the metal nib) to the positive input of the multimeter.

6.3 Replacing the Pen Tip
The multimeter features a detachable nickel-plated pen tip for the red test lead. To replace it:
- Carefully unscrew the existing metal nib using pliers. It is recommended to put some paper towels around the tip to reduce wear and tear during this process.
- Replace with the desired measuring nib.
- Screw the new nib securely into place.

7. Operating Instructions
7.1 Power On/Off
- Power On: Short press the power button (refer to the parts diagram). The device will power on and enter AUTO mode.
- Power Off: Long press the power button to turn off the device. The multimeter also features an automatic shut-down after 5 minutes of inactivity.
7.2 Function Switching
The multimeter has two function switch buttons. Refer to the parts diagram for their locations.
- Main Function Switch (AUTO, AC, F, Ω, Hz): Single press the button labeled with these functions to cycle through them.
- Special Function Switch (NCV, LIVE, P): Single press the button labeled with these functions to cycle through them.
7.3 Flashlight Function
- Turn On/Off Flashlight: Long press the flashlight button (refer to parts diagram).

7.4 Data Hold
- Activate/Deactivate Data Hold: Press the 'HOLD' button to freeze the current reading on the display. Press it again to release.
7.5 NCV (Non-Contact Voltage) Induction Detection
This function allows for safe detection of AC voltage without direct contact.
- Select the NCV mode using the special function switch.
- Bring the tip of the multimeter close to the suspected AC voltage source.
- When AC voltage is detected, the screen will display "----", a buzzer will sound, and the LED alarm light will turn red. The frequency of the buzzer and light indicates the strength of the detected field.

7.6 Phase Sequence Detection
This function helps determine the phase sequence in three-phase systems.
- Select the 'P' (Phase Sequence) mode using the special function switch.
- Bring the pen tip close to the phase lines (e.g., A, B, C) sequentially.
- After testing the phases, the display screen will show the test result, indicating the phase sequence (e.g., "PABC").

7.7 Other Measurement Functions (Voltage, Resistance, Diode, Continuity)
For other measurement functions, select the appropriate mode (AUTO, AC, F, Ω, Hz) using the main function switch and connect the test leads to the circuit or component as required for the specific measurement.
- Voltage Measurement (AC/DC): Select 'AC' or 'AUTO' mode. Connect the test leads in parallel to the circuit or component to measure voltage.
- Resistance Measurement: Select 'Ω' or 'AUTO' mode. Connect the test leads across the component to measure resistance. Ensure the circuit is de-energized before measuring resistance.
- Diode Test: Select 'Diode' mode (often integrated with continuity or resistance). Connect the test leads across the diode.
- Continuity Test: Select 'Continuity' mode (often indicated by a buzzer symbol). Connect the test leads across the circuit. A continuous beep indicates continuity.
8. Maintenance
8.1 Cleaning
- Wipe the multimeter casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure the device is powered off and disconnected from any circuits before cleaning.
8.2 Battery Replacement
Replace the AAA battery when the low battery indicator appears on the display to ensure accurate measurements.
8.3 Storage
- Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures.
- If storing for an extended period, remove the battery to prevent leakage.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Multimeter does not power on. | Low or dead battery; incorrect battery installation. | Replace the AAA battery; ensure correct polarity. |
| Inaccurate readings. | Incorrect measurement mode selected; poor contact with circuit/component; battery low. | Verify the correct function mode; ensure firm contact with test leads; replace battery if low. |
| NCV detection not working or inconsistent. | Not in NCV mode; too far from AC source; interference. | Ensure NCV mode is active; bring tip closer to the source; move away from other electrical fields. |
| Voice broadcast not working. | Voice function might be disabled (if applicable) or a temporary software glitch. | Check user manual for voice settings (if any); try restarting the device. |
10. User Tips
- Always double-check that the correct measurement mode is selected before making any measurements to prevent damage to the device or circuit.
- When using NCV detection, sweep the tip along the wire or outlet to pinpoint the live area more accurately.
- For resistance or continuity tests, ensure the circuit is completely de-energized to avoid false readings or damage.
- Keep the display clean for optimal readability, especially in low-light conditions where the VA reverse display excels.
11. Safety Information
WARNING: Failure to follow these safety instructions may result in electric shock, fire, or personal injury.
- Do not exceed the maximum input values specified for each measurement function.
- Do not use the multimeter if it appears damaged or if the test leads are compromised.
- Ensure your hands are dry and you are standing on an insulated surface when taking measurements.
- Always disconnect the test leads from the circuit before changing functions.
- Be cautious when working with voltages above 30V AC RMS, 42V peak, or 60V DC, as they pose a shock hazard.
- Keep the device out of reach of children.
- Refer to local and national safety codes for proper electrical work practices.
