13 3.Other ites -22- Attentions 1. Factors which affect the easureent precision and soe instruction: A. Electrical property: The conductivity of the etal, deterined by the aterial content and heat treatent, will finally influence the output of easureent, so please calibrate with the sae electrical property of the standard sheet as the substrate aterial. b. Thickness of substrate etal: Every instruent is subject to a critical thickness of a certain substrate etal which allows the easurent could be taken when the thickness is lager than the critical. This unit's critical thickness(iniu substrate thickness) is.5. c. Verge effect: The unit is sensitive to the steep change on the surface of the target piece. So the output obtained near the verge or inner angle of the piece is not reliable. Therefore, easureent on curved surface, the result is not reliable. d. Curvature: The curvature of the target piece ay affect the easureent result. This effect will be increased as the curvature's radius reduced. e. Roughness degree of the surface: The roughness degree of substrate etal and coating ay affect the easureent. The bigger the roughness degree is, the bigger the effect is. Rough surface will cause syste error and incidental error. You should increase the easureent nuber at different place to reduce incidental error. If the substrate etal is rough, you ust adjust point on the substrate etal which is not coated and has siilar roughness with the target one; or you can use ipregnant which can not erode the substrate etal to dissolve the coating, and then to adjust the point. f. Adhesive layer: The unit is sensitive to the attachent between the test head and the coating, so you ust clear the layer to ake sure the test head contact the coating diretly.. g. the detect head's pressure: The pressure on the target piece can affect the easureent value, so to aintain a basic constant pressure. h. Detect head's angle: The angle of the test head affects the easureent. You ust be sure the detect head to be contact the target piece is at a right angle. i. the target piece's distortion: The detect head can ake the target piece of soft coating distort, if the distortion is too big, the easureent value is not correct. 2. Attentions in operation: a. The property of substrate etal For eddy current ethod, standard pieces in line with the substrate in conductivity and roughness of the surface roughness is siilar. b. the thickness of the substrate: Check whether the substrate's thickness is less than the critical thickness

14 c. verge effect: Do not easure at the locations where there are steep shape change of the easured, i.e. Verge, hole or inner corner and so on. d. Curvature: Do not easure at the distorted surface. e. The readings: Because the readings ay not be identical all the tie, so you should several easureents at the sae area. The local difference of the coating also requests to easure several ties at the specified area especially rough surface. f. Cleanness of surface: You should clear all the adhesive layer on the surface like dust, grease, rust etc. Before taking easureent, but do not reove any coating. 3. About the easureent reading: a. As per statistics, single value in not reliable enough, so all the output readings are average value of ultiple easureents that is carried out by the unit within hundreds of illiseconds. b. To ensure ore precision reading, you can easure several ties, and then delete the ax error one, at last use analysis function to get five statistical data: average value (AVG), MAX, MIN, standard warp (dfr), data nuber (NO). c. According to the international standard, the final easure result can expressed as the following forula: CH=A+/-2D CH---the thickness of the coating A----the average value of the easure data (AVG) D-----standard warp (dfr) Maintenance and warranty Maintenance: 1. Replaceent and upkeep of battery: a. After power on, if an icon appears on the LCD, you need to replace the battery iediately, for details please refer to figures and contents on page 9 of this anual. b. Reove the battery fro the unit if it is not required for extended periods of tie in order to avoid daage to the battery copartent and the erosion resulting fro a battery leakage. 2. Do not store or use the unit in following circustances: a. Splashes of water or high levels of dust. b. Air of high salt or sulphur content. c. Air ixed with other gases or contents. d. High teperature or huidity (above5, 9%,) or direct sunlight. 3. Do not disasseble the unit or attept any internal alterations. 4.
