To calibrate the PeakTech 5220 Coating Thickness Gauge, you have three options: basic calibration, zero calibration, and multi-point calibration. Here are the steps for each calibration method:
1. Basic Calibration:
- Ensure that you have a smooth calibration sample with the same curvature radius and substrate as the sample you will be measuring.
- Follow the steps in the manual (Chapter 4.1) to perform basic calibration.
2. Zero Calibration:
- In measure mode, press the "CAL" key once to enter calibration mode.
- Place the probe on an uncoated sample and raise it after one beep. The LCD will show "X".
- Press and hold the "ZERO" key until you hear a series of beeps. The LCD will show "0" and the "ZERO" symbol.
- Repeat the previous step several times to obtain a mean value.
- Press the "CAL" key to exit calibration mode.
3. Multi-point Calibration:
- In measure mode, press the "CAL" key once to enter calibration mode.
- Perform zero calibration according to the steps mentioned above.
- Lay the calibration foil on an uncoated sample.
- Apply the probe and raise it after one beep. A reading will be shown on the LCD.
- Use the "Up" or "Down" key to adjust the reading to the required foil thickness value.
- Press the "Left" key to confirm and end the current calibration point.
- Repeat the previous steps for additional calibration points using different calibration foils.
- Press the "CAL" key to exit calibration mode.
Note: Each group (DIR or GEN) has individual zero calibration and multi-point calibration. It is recommended to work in single measure mode when calibrating.
Please refer to the manual (Chapter 4) for more detailed instructions and considerations for calibration.
