The load pressure of approximately 0.3N can leave an indent with soft and sensitive coatings. A coating thickness will be indicated which is too low.
Tip: Place a piece of hard plastic foil (between 30μm/1.2mils and 100μm/4mils, e.g. one of our measurement foils) between the measurement pole of the probe and the coating in order to reduce pressure and measure the total thickness. Subtract the foil thickness from the measurement value.
