5. Setup
5.1 Charging the Device
The DeWin ZL610 Rebar Scanner is equipped with a built-in 1800 mAh high-capacity battery. Before initial use, or if the battery indicator shows low power, ensure the device is fully charged.
- Connect the provided USB data cable to the charging port on the device.
- Connect the other end of the USB cable to a DC5V power source (e.g., a USB wall adapter, computer USB port).
- The indicator light will show the charging status. Once fully charged, disconnect the device from the power source.
5.2 Powering On/Off
- To Power On: Press and hold the power button (usually marked with a circle and a vertical line, as shown in Figure 3.1) until the display screen illuminates.
- To Power Off: Press and hold the power button until the device powers down. The device also features an automatic shutdown function, configurable up to 90 minutes of inactivity.
6. Operating Instructions
6.1 Basic Navigation
Use the navigation buttons (up, down, left, right, and confirm/power button) to move through menus and select options on the LCD screen.
6.2 Measurement Modes
The ZL610 Rebar Scanner offers various measurement modes for comprehensive analysis:
- Rebar Positioning: This mode helps locate the exact position of steel bars within concrete. Move the scanner slowly and evenly across the concrete surface. The display will indicate the presence and location of rebar.
- Protective Layer Thickness Measurement: The device measures the depth of the concrete cover over the rebar. Follow the on-screen prompts for accurate readings.
- Diameter Estimation: The scanner can estimate the diameter of the detected rebar. This feature may be optional or require specific settings.

6.3 Calibration
For optimal accuracy, periodic calibration may be required. Refer to the device's on-screen menu or the included CD for detailed calibration procedures. Typically, calibration involves scanning a known reference or following a guided process on the device.
6.4 Data Storage and Export
The device can store up to 200,000 rebar measurement points. Use the menu options to save measurement data. The included USB data cable and software (on the CD) can be used to export and analyze the stored data on a computer.
7. Maintenance
7.1 Cleaning
Keep the device clean and dry. Use a soft, slightly damp cloth for cleaning the exterior. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device's casing or screen.
