2. Device Configuration

2.1 Standard Package

The ARD3000 package contains:

1. Main detector unit

2. Charger

3. Backup battery

4. Black foam holder (with calibration chamber)

5. Tool kit

6. User manual and quick start guide

7. Product certificate

8. Wrist strap

Important Notes:

• The calibration chamber is specifically for device calibration—do not disassemble

• The safety case provides dustproof and waterproof protection

• Contact manufacturer immediately for any damaged or missing components

2.2 Operational Principle

The detector employs a dual-laser system:

• Visible targeting laser (green): For leak location (Class IIIR)

• Invisible detection laser: For methane concentration measurement (Class I)

By analyzing the reflected laser signal, the device calculates methane concentration in ppm·m units.

3. Operating Instructions

3.1 Basic Operations

Power On/Off:

• Press and hold power button until screen activates

• Same procedure for powering down

Laser Control:

• Short press power button to toggle lasers

• Warning: Green laser is Class IIIR—avoid direct eye exposure

Charging Procedure:

• Charge when battery drops below 20%

• Use original charger connected to bottom port

• Red light indicates charging; green indicates full charge

• Never charge in explosive atmospheres

3.2 Detection Modes

Two operational modes available:

High-Sensitivity Mode:

• Optimal for leaks within 30 meters

• Displays "Mode: High-sensitivity" on screen

Long-Distance Mode:

• Suitable for leaks up to 200 meters

• Displays "Mode: Long-distance"

• Adjustable distance settings available

Mode switching: Long press M button until desired mode appears

3.3 Targeting Methods

Laser Targeting:

• Ideal for close-range and low-light conditions

• Activates visible green beam

Sight Lens Targeting:

• Preferred for long-distance and bright environments

• Displays red dot in sight lens center

• Calibration: Adjust sight at 30m distance until red dot aligns with green laser

3.4 Detection Essentials

1. Confirm methane accumulation in laser path

2. Ensure unobstructed laser transmission

3. Verify adequate reflective surface for signal return

Surface Reflectivity Guide:

• Poor surfaces: Black walls, mirrors

• Good surfaces: Concrete walls, plaster

• Monitor signal strength indicator (top-left screen)

3.5 Common Mistakes

1. Excessive movement speed causing false alarms

2. Obstructed laser path altering distance readings

3. Dual laser points in high-reflectance corners

4. Detecting methane through thin PE pipes

5. Pointing laser at sky with no return signal

4. Parameter Configuration

4.1 Menu Navigation

Short press M button to access menu; navigate with arrow keys.

4.2 Alarm Settings

Configurable thresholds:

• Long-distance minimum alarm value

• High-sensitivity fluctuation threshold

4.3 System Settings

Submenu options include:

Offset Adjustment:

• Compensates for known ambient concentrations

• "Offset" icon appears when active

Distance Settings:

• Range: 1-10 (near to far)

• Higher values increase false alarm probability

Response Speed:

• Selectable: Fast/Medium/Slow

Unit Selection:

• Options: ppm/%LEL/%VOL

Language Selection:

• Supports Chinese/English

4.4 Additional Settings

Audio Settings: Toggle alarm sounds

Calibration Procedure:

• Recommended monthly

• Place detector in calibration chamber

• 10-second countdown completes process

Historical Data: Stores last 30 measurements

Factory Reset: Restores default parameters
