2. Safety Information
Please read and understand all safety instructions before operating the gauge. Failure to do so may result in injury or damage to the instrument.
- Do not expose the gauge to extreme temperatures, direct sunlight, or high humidity.
- Avoid dropping the instrument or subjecting it to severe impacts.
- Keep the gauge away from strong magnetic fields.
- Do not attempt to disassemble or repair the gauge yourself. Refer all servicing to qualified personnel.
- Ensure the measurement surface is clean and free from debris to prevent damage to the probe and ensure accurate readings.
- The gauge has an IP64 rating, indicating protection against dust ingress and splashing water from any direction. However, it is not waterproof and should not be submerged.
3. What's in the Box
Upon unboxing, please verify that all components are present:
- Elcometer 415 Gauge
- Check Piece
- Foil Set
If any items are missing or damaged, please contact your supplier immediately.
4. Setup
4.1. Initial Power On
The Elcometer 415 Gauge is typically supplied with batteries pre-installed. To power on the device, press and hold the power button located on the front panel until the display illuminates.
4.2. Calibration
For accurate measurements, the gauge requires calibration. The Elcometer 415 supports both 1-point and 2-point calibration methods to ensure precision on smooth and thin coated substrates.
- 1-Point Calibration: This method is suitable for most applications. Place the gauge on a known uncoated substrate (e.g., the supplied check piece) and follow the on-screen prompts to set the zero point.
- 2-Point Calibration: For enhanced accuracy, especially on specific materials or thickness ranges, use the supplied foil set. First, perform a 1-point calibration. Then, place a foil of known thickness on the uncoated substrate and calibrate the second point according to the gauge's instructions.
Refer to the on-screen menu for detailed calibration procedures.
5. Operating the Gauge
5.1. Taking a Measurement
Once calibrated, place the probe of the gauge firmly and perpendicularly onto the coated surface. The measurement will be displayed instantly on the screen. The gauge is capable of taking over 60 readings per minute, significantly reducing inspection times.

5.2. Display Interpretation
The large, clear display shows the measurement in micrometers (µm) or mils (mils). Additional icons indicate battery status, measurement mode, and connectivity status (e.g., Bluetooth if applicable).
5.3. Data Logging and Transfer
The Elcometer 415 features data logging capabilities. Measurements can be stored internally and transferred to a computer via USB. Use the ElcoMaster software for instant report generation and further analysis of your data.

6. Maintenance
6.1. Cleaning
To clean the gauge, wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the scratch, solvent, and powder resistant display. Ensure the probe tip is kept clean and free of debris for accurate readings.
6.2. Storage
When not in use, store the Elcometer 415 in its protective case in a dry, cool environment, away from direct sunlight and extreme temperatures. Remove batteries if the gauge will not be used for an extended period to prevent leakage.
7. Troubleshooting
This section addresses common issues you might encounter with your Elcometer 415 Gauge.
| Problem | Possible Cause | Solution |
