2. Safety Information
Always prioritize safety when working with electrical systems. This device is rated for CAT IV 1000V measurement environments, indicating a high level of protection against transient overvoltages. Adhere to all local and national safety codes.
- Do not use the tester if it appears damaged or is not operating correctly.
- Ensure the battery compartment is securely closed before use.
- Always test on a known live circuit first to confirm the tester is functioning.
- Non-contact detection does not guarantee the absence of voltage. Always verify with a contact method if necessary.
- Keep hands and fingers away from the probe tip during testing.

4. Setup
Battery Installation:
- Unscrew the battery cover at the bottom of the tester.
- Insert two 1.5V AAA batteries, ensuring correct polarity (+/-).
- Securely replace the battery cover.
5. Operating Instructions
Power On/Off:
- Press the Power Button to turn the tester on. The LCD will illuminate.
- Press and hold the Power Button again to turn the tester off.
- The device will automatically shut off after 5 minutes of inactivity to conserve battery.
Dual-Range Voltage Sensitivity:
The KTL01 offers two sensitivity modes for various applications:
- High Sensitivity Mode (12V-1000V AC): Suitable for general household wiring, outlets, and circuit breakers.
- Low Sensitivity Mode (70V-1000V AC): Ideal for sensitive devices like doorbells, thermostats, and irrigation systems to minimize false alarms.
Press the SENS Button to switch between high and low sensitivity modes. The LCD will indicate the current mode.

Non-Contact AC Voltage Detection (Live/Neutral Wire):
- Turn on the tester and select the desired sensitivity mode.
- Place the probe tip near the wire, outlet, or component you wish to test.
- If AC voltage is detected, the signal indicator will light up (red for live/high voltage, green for low voltage/no current), the buzzer will sound, and the LCD will display the signal strength percentage and bar graph. The buzzer frequency increases with stronger voltage.
Breakpoint Finder:
To locate a breakpoint in a live wire:
- Ensure the wire is live and the tester is in an appropriate sensitivity mode.
- Move the probe along the length of the wire.
- The tester will indicate voltage presence up to the breakpoint. The absence of a signal beyond a certain point indicates a break in the circuit.

Flashlight Operation:
- Press the Flashlight Switch to turn the built-in LED flashlight on.
- Press the Flashlight Switch again to turn it off.
