2. Safety Guidelines
Always prioritize safety when working with electrical systems. Failure to follow these safety instructions may result in electric shock, fire, or personal injury.
- Read the Manual: Thoroughly read and understand all instructions before using the device.
- Inspect Before Use: Before each use, inspect the device for any damage, cracks, or exposed wiring. Do not use if damaged.
- Voltage Limits: Do not attempt to measure voltages outside the specified range of 3-500V AC.
- Insulation: Ensure your hands are dry and you are standing on an insulated surface when testing live circuits.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, such as safety glasses and insulated gloves, when working with electricity.
- Non-Contact Detection: Non-contact voltage detection is a preliminary test. Always verify with direct contact measurement when possible and safe.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings.
- Children: Keep this device out of reach of children.

4. Getting Started
Battery Installation:
The KTS02 is powered by AAA batteries (not always included). Ensure correct polarity during installation.
- Locate the battery compartment cap at the end of the handle.
- Twist or slide the cap to open the compartment.
- Insert the required AAA batteries, observing the polarity markings (+/-).
- Securely close the battery compartment cap.
5. Operating Instructions
5.1 Power On/Off
Press the power button (usually marked with ⑂ ) to turn the device on or off. The LCD will illuminate upon activation.
5.2 AC Contact Voltage Measurement
This mode allows for direct measurement of AC voltage.
- Ensure the device is powered on.
- Press the AC Contact Test Button (often marked with a 'V' or wave symbol).
- Carefully touch the metal probe tip to the conductor or terminal you wish to test.
- The LCD will display the measured AC voltage. An audible beep may also sound.

5.3 Non-Contact Voltage (NCV) Detection
Use NCV mode to detect the presence of AC voltage without direct contact, enhancing safety.
- Ensure the device is powered on.
- Bring the tip of the tester close to the wire, outlet, or breaker panel.
- If AC voltage is detected, the LCD will indicate signal strength (e.g., 'HI' for high voltage) and an audible buzzer will sound.

5.4 Live Wire Identification
This function helps identify live wires in an electrical system.
- In AC Contact Voltage Measurement mode, touch the probe tip to the wire.
- A higher voltage reading or a specific indicator on the LCD (refer to device display for specific symbols) typically signifies a live wire.
- A lower or zero reading indicates a neutral or ground wire.
5.5 Continuity Test
Test the continuity of circuits, wires, switches, or fuses.
- Ensure the circuit or component is de-energized before testing continuity.
- Press the Continuity Test Button (often marked with a speaker or wave symbol).
- Touch the probe tip to one end of the component and the other end to a reference point (e.g., your finger on the metal cap if applicable, or another part of the circuit).
- A continuous beep and a 'Connected' indication on the LCD signify continuity. No beep or a 'Disconnected' indication means an open circuit.

5.6 Breakpoint Test
Locate breaks in insulated wires.
- Ensure the wire is connected to a live AC source at one end.
- Use the NCV detection mode.
- Run the tip of the tester along the insulated wire.
- The tester will indicate voltage up to the point of the break. The absence of a signal beyond a certain point indicates a break in the wire.

5.7 Screwdriver Function
The integrated slotted screwdriver can be used for light-duty fastening tasks.
- Ensure the electrical circuit is de-energized before using the screwdriver on electrical components.
- Align the slotted tip with the screw head.
- Turn the handle to tighten or loosen the screw.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity or replace with new AAA batteries. |
| Inaccurate voltage readings. | Low battery, environmental interference, or improper contact. | Replace batteries. Ensure firm contact with the conductor. Avoid strong electromagnetic fields. |
| NCV not detecting voltage. | Voltage too low, thick insulation, or device malfunction. | Ensure voltage is within detectable range. Try direct contact measurement if safe. |
| Continuity test fails on a known good circuit. | Poor contact or device malfunction. | Ensure firm contact. Test on a known continuous wire to verify device function. |
