2. Safety Information
Always adhere to safety precautions to prevent electric shock or personal injury.
General Safety Guidelines:
- Do not exceed the maximum input value specified for each measurement range.
- Ensure the test leads are properly connected and in good condition before use.
- Do not use the multimeter if it appears damaged or if the casing is open.
- Exercise extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
- Keep fingers behind the finger guards on the test probes during measurements.
- Do not operate the multimeter in explosive gas, vapor, or dusty environments.
- Always disconnect power to the circuit and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
- The ABS casing provides electrical insulation and protection against accidental drops.

6. Setup
Initial Charging:
The multimeter is equipped with a built-in 3.7V lithium battery. Before first use, or if the battery indicator shows low power, connect the device to a USB power source using the provided USB cable. The display will indicate charging status.
Connecting Test Probes:
- Insert the black test lead into the 'COM' (Common) input jack.
- Insert the red test lead into the 'INPUT' jack for most voltage, resistance, capacitance, and diode measurements.
7. Operating Instructions
Power On/Off:
Press the Switch Button (power symbol) to turn the multimeter on. Press and hold the same button to turn it off. The device features automatic shutdown after a period of inactivity to conserve battery.
Automatic Measurement Mode:
Upon powering on, the multimeter defaults to 'AUTO' mode. In this mode, the device automatically identifies and measures AC/DC voltage, resistance, and continuity without manual range selection. Simply connect the probes to the circuit or component to be measured.
Manual Mode Selection:
Press the Function Mode Switching Button (labeled 'AUTO SEL' or with mode symbols) to cycle through specific measurement functions such as:
- Voltage (AC/DC): For measuring electrical potential difference.
- Resistance (Ω): For measuring electrical resistance.
- Capacitance (F): For measuring capacitance of components.
- Diode Test: For checking the functionality of diodes.
- Continuity: For checking if a circuit is complete (audible beep for continuity).
Non-Contact Voltage (NCV) Detection:
The NCV function allows for detecting AC voltage without direct contact with wires. Place the NCV sensing area (top of the multimeter) near the conductor. The device will indicate the presence of AC voltage through visual and audible alerts.

Live Wire Detection:
To identify live and neutral wires, select the 'LIVE' mode. Insert the red probe into the suspected live wire. The display will show a strong signal (often red indication) for a live wire and a weak signal (often green indication) for a neutral wire.

Flashlight and Backlight:
Press the Flashlight and Backlight Button to turn on the built-in flashlight for working in dimly lit areas. Press it again to turn off. The display backlight automatically adjusts or can be toggled with this button.

8. Maintenance
Cleaning:
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is powered off and disconnected from any circuits before cleaning.
Storage:
When not in use for extended periods, store the multimeter in its protective storage bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the battery is adequately charged before long-term storage.
9. Troubleshooting
- No Display/Power: Ensure the battery is charged. Connect to a USB power source to charge.
- Inaccurate Readings: Check test lead connections. Ensure the correct measurement mode is selected (if not in AUTO mode). Verify the component or circuit is properly isolated if required.
- No NCV Detection: Ensure the NCV sensing area is close enough to the AC voltage source.
- Device Not Responding: Try turning the device off and on again. If issues persist, contact customer support.
