2. Safety Information

To ensure safe operation and prevent personal injury or damage to the device, please read and understand all safety instructions before use.

• Always assume that any circuit is live until it has been confirmed otherwise.
• Do not use the device if it appears damaged or is not operating properly.
• Do not exceed the maximum rated voltage of CAT II 1000V.
• Keep the device dry and clean.
• Do not attempt to repair or modify the device. Refer to qualified personnel for service.
• When using the flashlight function, avoid directing the light directly into eyes.

3. Setup

3.1 Battery Installation

The AVD07 requires two 1.5V AAA batteries (not included) for operation.

1. Locate the battery compartment cover at the bottom of the device.
2. Slide or unclip the cover to open the battery compartment.
3. Insert two 1.5V AAA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
4. Close the battery compartment cover securely.

4. Operating Instructions

4.1 Power On/Off

To power on the device, slide the power switch to the "ON" position. The device will perform a self-test. To power off, slide the switch to "OFF". The device also features an auto power-off function to conserve battery life if inactive for a period.

4.2 Mode Selection (Auto/Manual)

The AVD07 operates in two modes: Auto Mode and Manual Mode. Press the "MODE" button to switch between these modes.

• Auto Mode: Automatically adjusts sensitivity to detect voltage within the range of 48V-1000V AC. This is suitable for general detection.
• Manual Mode: Allows for more precise detection with adjustable sensitivity, covering a range of 12V-1000V AC. This mode is useful for distinguishing between different voltage levels or in noisy electrical environments.

4.3 Voltage Detection and Indication

When the detector senses AC voltage, the LED indicators will light up and an audible alarm will sound. The number and color of illuminated LEDs indicate the strength of the detected voltage:

• Green LEDs: Indicate low voltage or weak signal.
• Yellow LEDs: Indicate medium voltage or moderate signal.
• Red LEDs: Indicate high voltage or strong signal.

4.4 Live/Neutral Wire Identification

The AVD07 can help distinguish between live and neutral wires. When testing an outlet or wire:

• Live Wire: The detector will show a strong signal (more LEDs, typically red/yellow) and a rapid audible alarm.
• Neutral Wire: The detector will show a weaker or no signal (fewer or no LEDs, typically green) and a slower or no audible alarm.

4.5 Fireline/Zero Line Test

This feature assists in identifying the fireline (live) and zero line (neutral) in dense wiring environments.

• Fireline Test: Place the sensor end of the measuring pen near the wire. If it's the fireline, the detector will show a strong induction signal (more LEDs, rapid alarm).
• Zero Line Test: If the detector shows a weak induction signal or no induction, it indicates the zero line.

4.6 Breakpoint Location

The AVD07 can help locate breakpoints in live wires by detecting changes in voltage strength along the wire.

1. Move the detector along the insulated wire.
2. The point where the signal (LEDs and sound) abruptly stops or significantly weakens indicates a potential breakpoint.

4.7 Flashlight Function

The integrated LED spotlight can be activated to illuminate dark work areas. Refer to the safety section regarding direct eye exposure.

5. Maintenance

• Cleaning: Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low battery indicator appears or if the device does not power on. Always use new 1.5V AAA batteries.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
