GOLDEN BLUE CG02 Coating Thickness Gauge User Manual

1. Introduction

The GOLDEN BLUE CG02 Coating Thickness Gauge is a precision instrument designed for measuring the thickness of non-magnetic coatings on magnetic metal substrates (Fe) and non-conductive coatings on non-magnetic metal substrates (NFe). This device is ideal for applications such as automotive paint inspection, metal processing, and quality control, providing accurate and reliable measurements.

This manual provides detailed instructions for the proper setup, operation, and maintenance of your CG02 gauge to ensure optimal performance and longevity.

2. Safety Information

• Read all instructions carefully before using the device.
• Do not attempt to disassemble or modify the gauge. This will void the warranty and may cause damage.
• Keep the device away from strong magnetic fields, high temperatures, and corrosive environments.
• Ensure the battery compartment is securely closed to prevent dust and moisture ingress.
• Dispose of batteries according to local regulations.
• Use only the specified battery type (AAA*2).

This image highlights the LCD display, control buttons (MAX/MIN, Power/Unit, MODE, CAL, ZERO), and the sensitive thickness probe at the bottom. It also shows the anti-slip concave-convex design and indicates the low battery symbol, backlight, and digital display features.

• Sensitive Thickness Probe: Located at the bottom, used for contact measurement.
• LCD Bright Screen: Displays measurement readings, mode, unit, and battery status.
• Power Button (Center): Long press to turn ON/OFF. Single press to switch measurement units (µm/mil).
• MODE Button: Single press to switch between Single and Continuous measurement modes. Long press to set upper/lower limits.
• CAL Button (Left): Used for calibration. Also functions as 'up' or 'increase' during settings.
• ZERO Button (Right): Used for zero calibration. Also functions as 'down' or 'decrease' during settings.
• MAX/MIN Button: Displays maximum and minimum readings in continuous measurement mode.

5. Setup

5.1 Battery Installation

1. Locate the battery compartment cover on the back of the device.
2. Slide or unclip the cover to open.
3. Insert two AAA batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

5.2 Power On/Off

• To Power On: Long press the Power button. The LCD screen will light up.
• To Power Off: Long press the Power button again. The device will also automatically shut down after ten minutes of inactivity to conserve battery.

6. Calibration

Accurate calibration is crucial for precise measurements. The CG02 gauge supports calibration on both iron-based (Fe) and non-ferrous (NFe) substrates using standard films.

Figure 6.1: Calibration trimming for iron-based (Fe) and non-ferrous (NFe) substrates. The image shows two gauges, one calibrated for Fe (1005 µm) and one for NFe (50 µm), demonstrating the use of standard boards for fine-tuning.

Figure 6.2: Calibration standard plates. This image displays a set of five transparent calibration films with thicknesses of 50 µm, 99 µm, 248 µm, 500 µm, and 1005 µm, along with two metal calibration substrates (Fe and NFe).

6.1 Zero Calibration

1. Place the gauge probe directly onto the bare iron (Fe) substrate.
2. Press the ZERO button. The display should show "0.0" or a very small value.
3. Repeat the process for the bare non-ferrous (NFe) substrate.

6.2 Multi-Point Calibration (4-point smooth calibration)

This method uses standard calibration films to ensure accuracy across the measurement range.

1. Perform Zero Calibration as described above.
2. Place a standard calibration film (e.g., 50 µm) on the appropriate substrate (Fe or NFe).
3. Place the gauge probe onto the film.
4. Press the CAL button. The display will show a value. Use the CAL (up) and ZERO (down) buttons to adjust the displayed value to match the known thickness of the film.
5. Repeat this process for other standard calibration films (e.g., 99 µm, 248 µm, 500 µm, 1005 µm) to cover the desired measurement range.
6. After adjusting, press the MODE button to save the calibration and exit.

7. Operating Instructions

7.1 Measurement Modes

• Single Measurement Mode: Press the MODE button until "SINGLE" appears on the display. In this mode, the gauge takes one measurement each time the probe is placed on the surface.
• Continuous Measurement Mode: Press the MODE button until "CONTINUOUS" appears. In this mode, the gauge continuously measures as the probe is moved across the surface, updating the display in real-time.

7.2 Unit Switching

To switch between micrometers (µm) and mils (mil), short press the Power button.

7.3 Setting High & Low Alerts

The CG02 allows you to set upper and lower thickness limits. If a measurement falls outside these limits, the gauge will provide an alert.

Figure 7.1: Setting high and low alerts. This image illustrates how to set upper and lower thickness alarm limits by long-pressing the MODE button and adjusting values with CAL and ZERO. It also shows the "Di Di Di" sound and red/green LED lights indicating when the set limit is exceeded.

1. Long press the MODE button until the alarm setting interface appears.
2. Use the CAL and ZERO buttons to adjust the upper limit value.
3. Press MODE again to switch to the lower limit setting.
4. Use the CAL and ZERO buttons to adjust the lower limit value.
5. Press MODE to save the settings and exit.
6. When a measurement exceeds the set limits, the gauge will emit an audible "Di Di Di" alert and flash red/green LED lights.

7.4 Taking Measurements

1. Ensure the gauge is calibrated for the material you are measuring (Fe or NFe).
2. Select your desired measurement mode (Single or Continuous) and unit (µm or mil).
3. Place the probe gently and perpendicularly onto the coated surface.
4. Read the thickness value displayed on the LCD screen.
5. For continuous measurements, slide the probe smoothly across the surface.

7.5 Data Storage

The device features 6 groups of data storage, allowing you to record and compare measurements from different areas. Refer to the on-screen prompts or specific button combinations for saving and recalling data groups.

8. Maintenance

• Cleaning: Wipe the gauge body with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the probe tip clean and free of debris.
• Storage: Store the gauge in its original box or a protective case when not in use. Keep it in a dry environment, away from extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display. Remove batteries if the device will not be used for an extended period.
