Linshang LS237 Car Paint Thickness Gauge User Manual

1. Introduction

The Linshang LS237 Car Paint Thickness Gauge is a specialized instrument designed for precise automotive paint thickness inspection. This device accurately measures paint thickness on both ferrous (iron) and aluminum materials, identifies non-metallic surfaces, and intelligently detects ferrous putty and iron galvanized coatings. It features a user-friendly three-color backlight and indicator display, a long-lasting rechargeable lithium battery, and Bluetooth connectivity for seamless integration with a mobile application to generate and share inspection reports.

2. Key Features

• Dual-Material Measurement: Measures paint thickness on both ferrous (Fe) and aluminum (Al) substrates.
• Non-Metallic Identification: Capable of identifying non-metallic surfaces.
• Ferrous Putty Detection: Intelligently identifies ferrous putty and iron galvanized coatings.
• Three-Color Display: Features a three-color backlight and indicator display, where the screen and buttons change color based on paint thickness readings for quick visual assessment.
• Rechargeable Battery: Equipped with a 3.7V@1200mAh rechargeable lithium battery for extended use.
• Energy Efficient: Designed for ultra-low power consumption.
• Bluetooth Connectivity: Connects to a mobile application via Bluetooth for generating, saving, and sharing test reports.
• Wide Measuring Range: Offers a broad measurement range of 0.0-3500μm.
• Durable Probe: Utilizes a robust Ruby probe tip for accurate and consistent measurements.

3. Setup

3.1 Unpacking

Carefully remove the LS237 device and any accessories from its packaging. Inspect for any signs of damage.

3.2 Charging the Device

Before first use, fully charge the device. The LS237 supports Type-C data line charging. Connect the provided Type-C cable to the device's charging port and to a suitable USB power source. The device is designed for long endurance and energy saving.

3.3 Power On/Off

To power on the device, press and hold the Power button located on the front of the gauge. To power off, press and hold the Power button again until the display turns off.

4. Operating Instructions

4.1 Measurement Principle

The LS237 uses two primary measurement principles:

• Ferrous (Fe) Substrates: Utilizes the Hall effect.
• Non-Ferrous (NFe) / Aluminum (Al) Substrates: Utilizes the Eddy current principle.

4.2 Taking a Measurement

Place the Ruby probe tip firmly and perpendicularly onto the surface to be measured. The device will automatically detect the substrate type (Fe, Al, or non-metal) and display the coating thickness. The measurement interval is approximately 0.5 seconds.

4.3 Interpreting the Display

The 128x48 dot matrix LCD will show the measurement in micrometers (μm) or mils (mil). The screen and buttons will illuminate in one of three colors to indicate different thickness ranges or conditions, providing a quick visual cue.

4.4 Identifying Ferrous Putty

In Fe/Al mode, the LS237 can automatically identify ferrous putty. If putty is detected, the instrument will display a specific message, such as 'Ferrous putty!', along with the thickness reading, often accompanied by a red backlight indicator.

4.5 Examples of Measurement Applications

The LS237 can be used to test various car body types:

• Tests iron galvanized car body
• Tests iron car body
• Tests aluminum car body
• Tests non-metal car body

4.6 Using the Mobile APP

The device features Bluetooth connectivity, allowing it to operate online with a dedicated mobile application. The app enables users to generate test reports, save measurement data, and share reports easily.

5. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Probe Care: Keep the Ruby probe tip clean and free from debris to ensure accurate measurements. Avoid dropping or impacting the probe.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, especially if it will be stored for an extended period.

6. Troubleshooting

6.1 Device Not Powering On

• Ensure the battery is sufficiently charged. Connect the device to a charger and wait for a few minutes before attempting to power on again.
• Verify the power button is pressed and held correctly.

6.2 Inaccurate Readings

• Ensure the probe tip is clean and free from any foreign material.
• Make sure the probe is placed firmly and perpendicularly on the measurement surface.
• Verify the surface is clean and dry.
• Check if the minimum substrate thickness requirements are met (Fe: 0.2mm / Al: 0.05mm).

6.3 Bluetooth Connection Issues

• Ensure Bluetooth is enabled on both the LS237 and your mobile device.
• Make sure the LS237 is within range of your mobile device.
• Restart both the LS237 and your mobile device, then try pairing again.
• Ensure the mobile application is up to date.

6.4 Charging Indicator Behavior

If the charging indicator appears to be 'running' or inconsistent, it typically signifies that the device is actively charging. A steady indicator or a specific color change usually indicates a full charge. Refer to the device's display for battery status or consult the app for detailed battery information.

7. Specifications

8. User Tips

• Charging Indication: When charging, the battery icon on the display may show a 'running' animation. This indicates active charging. The animation will typically stop or change to a solid icon when fully charged.
• Language Settings: The device supports multiple languages including English, Russian, Turkish, Ukrainian, and Chinese. Refer to the device's menu settings to select your preferred language.

9. Warranty and Support

For warranty information, please refer to the documentation provided at the time of purchase or contact your retailer. Technical support may be available through the manufacturer's official channels. Keep your purchase receipt as proof of purchase.
