1. Introduction
The Neoteck Coating Thickness Gauge is a precision instrument designed for non-destructively measuring the thickness of plated and coated sheets on various metal substrates. Utilizing principles of electro-magnetic induction and the eddy current effect, it automatically detects the attribute of the substrate, making it suitable for both ferrous (Fe) metals like steel and non-ferrous (NFe) metals like aluminum and copper.
This gauge is an essential tool for material surface treatment, widely used in manufacturing, metal-processing, chemical industries, and commodity inspection. It performs reliably in laboratories, workshops, and outdoor environments.

2. Features
- Automatic Substrate Recognition: Designed with dual technology, the gauge automatically recognizes both ferrous (steel) and non-ferrous (aluminum/copper) substrates.
- High Precision Probe: Features a V-Groove design, allowing for easy and accurate measurement on curved metallic pipes and surfaces.
- HD Backlit Display: A large, easy-to-read LCD display shows metal type, working mode, measurement values (in µm or mils), and battery status.
- Measurement Modes: Supports both Single Point and Continuous measurement for versatile applications.
- Automatic Calibration: Simplifies the calibration process for consistent accuracy.
- Auto Power Off: Conserves battery life by automatically shutting down after 5 minutes of inactivity.
- Anti-Slip Groove Design: Ergonomic design for a secure and comfortable grip during use.

5. Setup
5.1 Battery Installation
- Locate the battery compartment on the back of the device.
- Open the battery cover.
- Insert 2 x AAA batteries, ensuring correct polarity (+/-).
- Close the battery cover securely.
5.2 Calibration
To ensure accurate measurements, it is recommended to calibrate the gauge before first use or if you suspect inaccurate readings.
- Long press and hold the 'CALIB/ZERO' button to enter calibration mode. The display will show a calibration indicator.
- Place the gauge probe firmly and flatly on the provided Iron Substrate (FE) for magnetic induction calibration.
- Follow the on-screen prompts to perform zero-point calibration.
- Repeat the process with the Aluminum Substrate (NFE) for eddy current calibration.
- For multi-point calibration, use the provided calibration films of varying thicknesses on the substrates as instructed by the device or manual.

6. Operating Instructions
6.1 Power On/Off
- To Power On: Press the 'ON/OFF' key (power button) for more than 0.5 seconds.
- To Power Off: Press and hold the 'ON/OFF' key until the screen blanks.
- Automatic Shut-off: The gauge will automatically switch off after 5 minutes of inactivity to conserve battery. This feature can be disabled via the device's menu/setup if available (refer to on-screen options).
6.2 Taking Measurements
- Ensure the gauge is powered on and calibrated.
- Place the probe of the gauge quickly and smoothly, vertically and lightly against the part to be measured.
- The measurement will be displayed on the LCD screen. The gauge automatically detects the substrate type (Fe or NFe).
6.3 Measurement Modes (SNG/CON)
The gauge supports two measurement modes: Single Point (SNG) and Continuous (CON).
- Single Point (SNG): Takes a single measurement each time the probe is applied to the surface.
- Continuous (CON): Allows for continuous scanning of a surface, providing real-time readings as the probe is moved. This mode is useful for quickly assessing larger areas.
To switch between SNG and CON modes, press the 'MODE/RESET' button.

6.4 Unit Switching (µm/mils)
To switch between micrometers (µm) and mils (mil) units, press the 'um/mils' button (Up Key).
7. Maintenance
- Battery Care: If the thickness gauge is to remain unused for a long period, remove the batteries and store them separately. This prevents potential damage from battery leakage or malfunction.
- Storage: Always store the thickness gauge in its carrying pouch when not in use to protect it from dust, moisture, and physical damage.
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Probe Protection: Ensure the probe tip is kept clean and free from debris to maintain measurement accuracy.
8. Troubleshooting
- No Display/Device Not Turning On: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Inaccurate Readings: Perform a calibration using the provided calibration plates and films. Ensure the probe is clean and applied flat against the surface. Verify the substrate material matches the gauge's capabilities (Fe/NFe).
- Display Error: Try turning the device off and on again. If the error persists, remove and reinsert batteries.
- Gauge Not Detecting Substrate: Ensure the substrate is a metal (ferrous or non-ferrous) and within the minimum thickness requirements (0.5mm for Fe, 0.3mm for NFe).
9. User Tips
- When measuring car paint, take multiple readings across different panels and average them for a more reliable assessment of paint consistency.
- For curved surfaces, utilize the V-Groove design of the probe to ensure stable contact and accurate readings.
- Always ensure the measurement surface is clean and dry for optimal accuracy.
- Keep the calibration films and substrates in good condition, as they are crucial for maintaining the accuracy of your gauge.
