1. Introduzione
The VOLTCRAFT SDM-115 Coating Thickness Gauge is designed to quickly and accurately measure the coating thickness on metallic surfaces. This device helps determine if a painted or repaired surface requires repainting or further repair. It is suitable for use on both ferromagnetic (e.g., steel) and non-ferromagnetic (e.g., aluminum) metals, offering a measurement range of 0-1000 µm.

4. Setup
4.1 Installazione di batterie
The VOLTCRAFT SDM-115 requires batteries for operation (not included). To install batteries:
- Locate the battery compartment cover, typically on the handle of the device.
- Fate scorrere o sganciate u coperchio per apre u compartimentu.
- Inserite e batterie necessarie, assicurendu a polarità curretta (+/-) cum'è indicata in l'internu di u compartimentu.
- Chiudere in modu sicuru u coperchiu di u compartimentu di a batteria.
5. Operating Instructions
5.1 Accensione / spegnimentu
Press and hold the trigger or power button (if available) to turn the device on. The display will illuminate. To turn off, press and hold the same button or wait for automatic shutdown.
5.2 Piglià una Misurazione
To take an accurate coating thickness measurement:
- Ensure the measurement surface is clean, dry, and free of debris.
- Place the sensor head of the gauge firmly and perpendicularly onto the surface to be measured.
- The device will automatically display the coating thickness reading on the screen.
- Lift the device from the surface to prepare for the next measurement.

5.3 Cambiamentu di unità di misura
The device supports measurement in both mils and micrometers (µm). To switch between units, press the button labeled mils/µm nantu à u pannellu di cuntrollu.
6. Calibrazione
For optimal accuracy, especially when measuring different materials or after prolonged use, two-point calibration is recommended. The device features a CAL button for initiating the calibration process.
While the exact steps for two-point calibration may vary, generally it involves:
- Placing the gauge on a known zero-thickness surface (e.g., bare metal).
- Pressendu u CAL button and following on-screen prompts to set the zero point.
- Placing the gauge on a surface with a known standard thickness (e.g., a calibration foil).
- Pressendu u CAL button again and using the arrow buttons to adjust the reading to match the known standard thickness.
- Confirming the calibration.
Refer to the detailed instructions provided with your specific calibration foils or the full product manual for precise calibration procedures.
7. Mantenimentu
7.1 Pulizia
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor head is kept clean and free of dust or residue for accurate readings.
7.2 Storage
Conservate l'apparechju in un locu frescu è asciuttu, luntanu da a luce diretta di u sole è da e temperature estreme. Sè vo u conservate per un periodu prolongatu, cacciate e batterie per impedisce perdite.
8. Risoluzione di prublemi
- L'apparechju ùn s'accende micca: Verificate l'installazione di e batterie è assicuratevi chì e batterie ùn sianu micca scariche. Rimpiazzate e batterie se necessariu.
- Letture imprecise o incoerenti:
- Ensure the sensor head is clean and free of debris.
- Perform a two-point calibration as described in Section 6.
- Verify the measurement surface is clean, dry, and flat.
- Ensure the device is placed perpendicularly and firmly on the surface.
- Device beeps excessively or shows unusually high values: This often indicates a need for calibration. Follow the calibration steps in Section 6 carefully. Ensure you are using appropriate calibration standards.
