3. Operating Instructions
3.1 Taking a Measurement
To obtain an accurate paint thickness reading:
- Ensure the meter is powered on.
- Place the probe of the Elcometer 311 firmly and flatly onto the painted surface you wish to measure.
- Hold the meter steady. The reading will appear almost instantly on the display.

The meter's display shows a reading of 5.5, indicating a paint thickness measurement. Right: This image features a hand holding the Elcometer 311 paint meter against a dark, possibly black, painted surface. The meter's screen clearly shows a reading of 4.5 mils, indicating the paint thickness.
3.2 Changing Measurement Units (Mils/Microns)
The Elcometer 311 allows you to switch between mils and microns. Refer to your device's specific button layout for the 'Units' or 'Mode' button. Typically, a short press of this button will toggle between the two measurement units.
3.3 Understanding Readings
The display will show the measured paint thickness. The unit (mils or µm/microns) will be indicated next to the numerical value. The automatic rotating display ensures the reading is always upright, regardless of the meter's orientation. The ambient light sensor adjusts screen brightness for optimal visibility.
The device is designed to operate reliably in both wet and dry conditions due to its IP64 dust and waterproof rating.
