1. Introducció
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.

3. Configuració
3.1 Desembalatge
Carefully remove the LS237 device and any accessories from its packaging. Inspect for any signs of damage.
3.2 Càrrega del dispositiu
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 Encès/Apagat
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. Instruccions de funcionament
4.1 Principi de mesura
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 Prendre una mesura
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 Interpretació de la pantalla
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.

Ex. 4.5amples 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. Manteniment
- Neteja: Netegeu el dispositiu amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents.
- Emmagatzematge: Guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Cura de la sonda: Keep the Ruby probe tip clean and free from debris to ensure accurate measurements. Avoid dropping or impacting the probe.
- Cura de la bateria: Per a una durada òptima de la bateria, eviteu descarregar-la completament amb freqüència. Carregueu el dispositiu regularment, sobretot si l'emmagatzemareu durant un període prolongat.
6. Solució De Problemes
6.1 El dispositiu no s'encén
- Ensure the battery is sufficiently charged. Connect the device to a charger and wait for a few minutes before attempting to power on again.
- Verifiqueu que el botó d'engegada estigui premut i mantingut premut correctament.
6.2 Lectures inexactes
- 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 Problemes de connexió Bluetooth
- 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.
