1. Introduction
The MiLESEEY MC996 Digital Coating Thickness Gauge is designed for precise measurement of non-magnetic coatings on magnetic metal substrates (ferrous, Fe) and non-conductive coatings on non-ferrous metal substrates (NF). This device features automatic F/NF mode detection, fast readings, zero and multi-point calibration, unit conversion (metric/imperial), single and continuous measurement modes, and an automatic shut-down function for energy saving. It is suitable for various applications including automotive, manufacturing, and quality inspection.

Key Components:
- 2.2" Backlit Screen: Displays measurement readings, units, battery status, and mode indicators.
- CALIB/ZERO Button: Used for zero calibration and reducing calibration data.
- um/mils Button: Switches between metric (µm) and imperial (mils) units, and increases calibration data.
- MODE/RESET Button: Switches between Single (SNG) and Continuous (CON) measurement modes, and resets to default settings.
- Power Button: Turns the device on and off.
- Detecting Sensor: Located at the bottom, used to contact the surface for measurement.
4. Setup
4.1 Battery Installation
- Locate the battery compartment on the back of the device.
- Open the battery cover.
- Insert two AAA batteries, ensuring correct polarity (+/-).
- Close the battery cover securely.
4.2 Initial Power On
Press the power button to turn on the device. The screen will light up, and the gauge will perform a self-check. Ensure the sensor is not touching any surface during power-on.
5. Operating Instructions
5.1 Measurement Modes
The gauge supports two measurement modes:
- SNG (Single Measurement): Takes one reading each time the sensor is placed on the surface.
- CON (Continuous Measurement): Continuously takes readings as the sensor is moved across the surface.
Press the MODE/RESET button to switch between SNG and CON modes.
5.2 Unit Conversion
Press the um/mils button to switch between micrometers (µm) and mils (mil).
5.3 Automatic F/NF Detection
The MC996 automatically detects the substrate material (Ferrous 'Fe' or Non-Ferrous 'NF') when the sensor is placed on the surface. The detected material type will be displayed on the screen.
Figure 5.1: The gauge's automatic detection of Ferrous (Fe) and Non-Ferrous (NF) materials, along with their respective measurement ranges and resolutions.
5.4 Taking a Measurement
- Ensure the gauge is powered on and calibrated (see Section 6).
- Place the detecting sensor firmly and perpendicularly onto the coated surface to be measured.
- The gauge will automatically detect the substrate type and display the coating thickness reading on the screen.
- For continuous measurement, slide the sensor across the surface. For single measurement, lift and re-place the sensor for each new reading.

6. Calibration
Calibration is crucial for accurate measurements. The MC996 supports zero calibration and multi-point calibration.
6.1 Zero Calibration
Zero calibration should be performed on an uncoated substrate of the same material as the one you intend to measure (e.g., bare iron for ferrous measurements, bare aluminum for non-ferrous measurements).
- Place the sensor firmly on the bare substrate.
- Press and hold the CALIB/ZERO button until the display shows "0.00" or a similar indication of zero.
- Release the button. The gauge is now zero-calibrated for that substrate type.
6.2 Multi-Points Calibration
Multi-points calibration uses standard foils of known thickness to ensure accuracy across the measurement range. Use the included calibration foils and substrates.
- Perform zero calibration first (Section 6.1).
- Place a calibration foil of known thickness onto the appropriate substrate (e.g., 100µm foil on the iron substrate).
- Place the sensor on top of the foil. The gauge will display a reading.
- Use the um/mils and CALIB/ZERO buttons to adjust the displayed value to match the known thickness of the foil.
- Repeat for other calibration foils to cover the desired measurement range.
7. Maintenance
7.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the sensor clean and free from debris to ensure accurate readings.
7.2 Battery Replacement
When the low battery indicator appears on the screen, replace the AAA batteries as described in Section 4.1.
7.3 Storage
Store the gauge in its carrying case in a dry, cool place, away from direct sunlight and extreme temperatures. Remove batteries if the device will not be used for an extended period.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries | Replace batteries, ensuring correct polarity. |
| Gauge powers on but does not take measurements | Internal error or sensor issue | Remove batteries for 30 seconds, then reinsert to reset the device. If the problem persists, contact support. |
| Inaccurate readings | Improper calibration, dirty sensor, or incorrect measurement technique | Perform zero and multi-point calibration (Section 6). Clean the sensor. Ensure the sensor is placed firmly and perpendicularly. |
| Display is dim or flickering | Low battery | Replace batteries. |
