This hand-held device for coating thickness measurement with a separate probe is a highly intelligent and accurate measuring device with which layer thicknesses can be measured quickly and accurately on almost all metal surfaces. The instrument not only displays the film thickness but also automatically identifies the metal base (Fe stands for magnetic metals such as iron and steel, nFe denotes non- magnetic metals such as aluminum, metal alloys and non-magnetic steel). With the device different coatings can be measured:  non-magnetic coatings, ceramics, enamels, plastics, rubber coatings;  magnetic base materials such as iron or steel, non-ferrous metals such as nickel and chromium;  corrosion protection coatings in the chemical and oil industries;  non-conductive paints;  plastic coatings and anodised coatings on non-magnetic conductive devices such as aircraft, household appliances, vehicles, completely alloyed doors and windows, as well as other aluminum products;  electrically conductive coating material. Specifications and prices of all CP Instruments devices can be found on our website: http://www.cp-instruments.pl. You will also find our contact details there. Our staff will gladly help you with any questions. 2 Safety information Please read this user manual carefully and completely before using the device for the first time.

Then you can choose between "single deletion" (deletion of individual data) and "total deletion" (deletion of all values). 4.10 Accuracy measurement The user can control the accuracy of the device according to the given reference standards. The device is supplied with standard plastic films. These can be used to test the measurement accuracy of the instrument with the help of supplied calibration blocks. They can also be used to protect the sensor on rough or hot surfaces. The measured value should be within the accuracy range specified in the operating instructions. For example, if the accuracy is specified as ± 2% + 2 μm, the measurement result should be between 47 and 53 μm when the Coating Thickness Gauge is used to measure a 50 μm film thickness plastic film. Otherwise, the device must be calibrated.

measurement. Therefore, it usually only needs to be tested before the measurement if the measured value is 0 when measuring an uncoated metal. If this is not the case, a zero point calibration should be performed. 4.11.1 Zero-point calibration Press the and select "Zero Point Calibration" by briefly pressing and "000" will flash on the screen. Then measure an uncoated substrate. When "0" is displayed on the screen, the zero calibration is successful. After this process, the instrument can usually be reused for accurate coating thickness measurements. Nevertheless, due to abnormal base materials or extreme environmental conditions, additive errors may occur. If this is the case, you can use the standard plastic films to perform a multipoint calibration. 4.11.2 Multipoint calibration Use the instrument to place standard plastic films on a calibration block if the value found is outside the accuracy limits of this manual. Lift the probe ("Pt1 ~ μm" flashes in the screen to "), press or for fast scrolling) to set the value of the actual thickness. Repeat this with other plastic films. The use of two of these standard plastic films is better for calibration than just one. For example, you can use a thin and, alternatively, a thick foil. If the coatings to be measured are relatively close to the thickness of the other, it is sufficient to use only a film of similar thickness for the calibration.

If zeroing with standard plastic films does not work, it may be necessary to reinitialize the device. First press briefly select "Reset", then "Complete Reset" and confirm with "Complete reset" will flash in the display and indicate together with a beep that the initialization is completed. To ensure high measurement accuracy, it is recommended to perform a zero point calibration after initialization. All previously saved values and settings are deleted after initialization and the device is reset to factory settings. Note: When measuring the coating thickness of alloys such as aluminum or stainless steel alloy, the instrument must be calibrated as follows: 1. Turn on the coating thickness gauge, initialize it to factory settings, and turn it off. 2. Turn it back on and calibrate it to 6 standard slides (if accuracy was affected, keep the unit away from any material during the entire calibration process).
