4. Thiết lập

4.1 Lắp đặt pin

The PM8908B requires two (2) 1.5V AAA batteries for operation.

1. Locate the rotatable battery cover at the top end of the detector.
2. Rotate the cover counter-clockwise to open it.
3. Lắp hai pin AAA 1.5V, đảm bảo đúng cực (+/-) như chỉ dẫn bên trong ngăn chứa pin.
4. Replace the battery cover by rotating it clockwise until it is securely closed.

The device will automatically power on after battery installation or when the power button is pressed.

5. Hướng dẫn vận hành

5.1 Bật/Tắt nguồn

• Press the power button (usually marked with “⑉”) to turn the detector on. The green LED will illuminate.
• To turn off, press and hold the power button for approximately 2 seconds. The device also features an auto power-off function to conserve battery life after a period of inactivity.

5.2 Dòng điện xoay chiều không tiếp xúctage Phát hiện

The PM8908B detects AC voltagmà không cần tiếp xúc trực tiếp với dây dẫn.

1. Bật máy dò.
2. Bring the detection tip close to the wire, outlet, or electrical component you wish to test.
3. Nếu AC voltage is detected, the red LED indicator will flash, and an audible alarm will sound. The frequency of the flashing and beeping increases with higher voltage or closer proximity to the source.

5.3 Điều chỉnh độ nhạy

The detector offers three levels of sensitivity (High, Medium, Low) for different detection scenarios.

• Press the alarm/sensitivity button (usually marked with a bell icon) to cycle through the sensitivity modes.
• The device will indicate the current sensitivity level through a combination of beeps or LED flashes.
• Use high sensitivity for detecting voltage from a greater distance or through insulation. Use low sensitivity for more precise localization of voltagcác nguồn e.

5.4 Zero Line and Fire Line Distinction

The PM8908B can automatically distinguish between the Zero (Neutral) Line and the Fire (Live) Line.

• When testing an AC outlet or cable, the detector will provide a stronger and more consistent alarm (faster flashing red LED and quicker beeps) when near the live wire.
• The neutral wire will typically result in no alarm or a significantly weaker/intermittent alarm, depending on the sensitivity setting and environmental factors.

5.5 Chức năng đèn pin

The built-in white LED flashlight assists in working in dark areas.

• Press the flashlight button (often integrated with the power button or a separate button) to turn the flashlight on or off.

6. Bảo trì

6.1 Thay thế pin

When the low battery indicator appears, replace the batteries as soon as possible to ensure accurate operation. Refer to Section 4.1 for battery installation instructions.

6.2 Vệ sinh

Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.

6.3 Lưu trữ

Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
