Foreword Dear Customer, with the purchase of a coatmaster® Flex, you have acquired a high-quality, precision product. In this manual we provide you with some instructions to help you to work successfully and productively with this device for many years. coatmaster AG has made every effort to manufacture a safe and high- quality device that complies with all applicable regulations.
(dust, high temperature) industrial environment. The patented measurement process used by the coatmaster® Flex is non-contact (as opposed to systems based on magnetic induction or ultrasound) and non-destructive. It can be applied on wet, powder, and cured coatings, regardless of the coating material, thickness, or color (including white).
Flex Applications The coatmaster® Flex is a flexible and robust handheld device for non-contact measurement of coatings. The coatmaster® Flex is unique and versatile and can be used in a wide variety of industries and industrial sectors: • Automotive •...
Functionality and Measuring Principle The coatmaster® works according to the principle of advanced thermal optics (ATO). The surface of the coating is heated with a light pulse. After brief heating by a few degrees, the surface is cooled by heat conduction to deeper areas of the coating and the substrate.
Flex Safety and Responsibility This section provides an overview of all relevant safety features for optimum personal protection and safe and trouble-free operation. Keep the operating instructions with the safety instructions so that you can refer to them later.
Table 3: Signs and icons Intended Use The coatmaster® Flex is intended exclusively for the measurement of coating thicknesses. The device should only be used as a handheld device. The device should not be mounted on a robot or fixture or operated for an extended period of time.

The following applications are prohibited: • Use of the equipment in environments where liquids may get into the device. • Introduction of any objects into the coatmaster® Flex or similar devices. • Unauthorized opening the device, other than for standard maintenance operations (see section 13.), voids the warranty and the manufacturer assumes no liability.
Before operating the coatmaster® Flex in any environment, check if the measurement area is under surveillance of flame detectors. If the flame detector is not listed in the above table, use the Flex in that area after receiving written confirmation either from coatmaster AG or from the supplier of the...

SNR value shown in the calibration report is SNR = 2090 (dimensionless). If the coatmaster® Flex is aimed at another surface if it is too far away from the coating, the SNR value for the measurement will decrease. We can set an SNR threshold to determine the minimum SNR value required of a measurement to be acceptable.
Calibration samples should cover the whole measurement range. If, for example, measurements with the Flex are to be conducted up to 150 µm, then a calibration sample at 150 µm should be used to ensure maximum accuracy of the Flex measurement. If the measurement value exceeds the maximum calibration measurement by a factor of 2, the Flex will not display the measurement value because of potentially high inaccuracy.
Flex measurement results at lower or higher thickness. For example, Flex thickness measurements are ok in the range of 80 μm, but we see that the Flex measures always around 10 μm too high in the range of 40 μm. Such systematic deviations can occur, for example, if an uncured coating is to be measured with the Flex on a cured coating.
(see section been selected in the application menu 8.4.). Hold the coatmaster® Flex as steadily as possible at a distance of approximately 5 cm from the sample (see Figure 52: Measurement). The measured surface is in the middle of the red circles and is approximately 2 mm in diameter.
