3.3 Power On/Off
Press the power button to turn the device on. The device features an auto-off function to save battery life after a period of inactivity.
4. Calibration
Accurate calibration is crucial for precise measurements. The WT230 supports both Basic Calibration and Zero Calibration.
Figure 4: Detailed instructions for Basic and Zero Calibration.
4.1 Basic Calibration
- Prepare the calibration foils and calibration substrate (magnetic and non-magnetic).
- Enter the calibration menu and select basic calibration.
- Place the calibration foils with corresponding thickness on the substrate according to the instrument display.
- When calibration is complete, the bottom of the screen will show "calibration complete".
- Magnetic metal substrate calibration and non-magnetic metal substrate calibration do not affect each other.
- Note: When the arrow is facing down during basic calibration, press the substrate; when the arrow is facing up, move the substrate away.
4.2 Zero Calibration
- Open the menu and select "Calibration/Zero Calibration".
- Press the coating meter gently against the substrate.
- The coating gauge will automatically calibrate the zero point.
- When calibration is complete, the meter automatically returns to the previous screen.
- Measurement can be performed after calibration is complete.

5. Operating Modes
The WT230 offers various modes to suit different measurement needs.
Figure 5: Illustration of Single and Continuous Measurement Modes.
5.1 Single Measurement Mode
Suitable for individual measurements. Place the probe on the desired surface, and the device will display a single reading.
5.2 Continuous Measurement Mode
Ideal for measuring along large areas. The device will continuously take readings as the probe is moved across the surface.
5.3 Unit Switching
Easily switch between micrometers (μm) and mils (mils) units using the dedicated button.
Figure 6: Unit switch and setup menu options.
5.4 High and Low Limit Alarm
Set high and low reading limits. The device will trigger an alarm if the coating thickness falls outside these predefined limits, useful for quick inspection.
5.5 Voice Feature
The device can audibly read out measurements, allowing users to focus on the measurement point without constantly looking at the screen.
Figure 7: The voice reading feature allows for hands-free data acquisition.
5.6 Auto Rotational Screen
The display automatically rotates 360° when the device's orientation changes, ensuring easy readability from any angle.

6. Measurement Applications
The WT230 is versatile and can measure coating thickness on various materials.
Figure 9: The WT230 can measure various coated objects.
6.1 Substrate Identification
The micron accuracy probe automatically identifies whether the underlying substrate is magnetic (Fe, e.g., steel, iron) or non-magnetic (NFe, e.g., copper, aluminum, zinc).

7. Data Management
The WT230 offers robust data storage and export capabilities.
7.1 Data Storage
The device can save up to 1500 readings in 100 groups, allowing for comprehensive data collection and analysis.
