The choice of those positions follows the expected behaviour of the component: bends, welds, low areas where liquid stagnates, stretches subject to erosion. <\/p>\n\n<p class=\"wp-block-paragraph\">For this structure to be useful it must remain identical over time. If in the next campaign the points are redefined, renumbered or taken roughly where they were, the comparison between the two series loses meaning: a difference in thickness becomes indistinguishable from a shift of the probe. Repeatability of position is, in this type of inspection, as important as the accuracy of the reading.  <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-cover is-light popmake-4066 popmake-739\" style=\"border-width:1px;min-height:250px;aspect-ratio:unset;\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"250\" class=\"wp-block-cover__image-background wp-image-727 size-full\" alt=\"\" src=\"https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=1200%2C250&#038;ssl=1\" data-object-fit=\"cover\" srcset=\"https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?w=1200&amp;ssl=1 1200w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=300%2C63&amp;ssl=1 300w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=1024%2C213&amp;ssl=1 1024w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=768%2C160&amp;ssl=1 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-30 has-background-dim\" style=\"background-color:#d3d6dc\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-container-core-cover-is-layout-15701bb7 wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-right has-ti-fg-color is-style-default has-luminous-vivid-amber-color has-text-color has-link-color wp-elements-1 wp-block-paragraph\" style=\"font-size:clamp(21.536px, 1.346rem + ((1vw - 3.2px) * 1.374), 35px);\"><strong>Need help choosing the right product?<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-right is-layout-flex wp-container-core-buttons-is-layout-b507c051 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button popmake-4066 popmake-739\"><a class=\"wp-block-button__link has-ti-accent-color has-cyan-bluish-gray-background-color has-text-color has-background has-link-color wp-element-button\">Contact us<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<p class=\"wp-block-paragraph\">The grid is the form this structure takes on the instrument.

With the scan mode of the CMX series, which acquires up to 250 readings per second, an area can be swept looking for the local minimum before recording the value of the point; on the MX1-DL and MX2-DL models scanning works at 200 Hz, on the ZX6-DL at 100 Hz. <\/p>\n<\/div>\n<\/div>\n\n<h2 class=\"wp-block-heading\">Recommended instruments<\/h2>\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th style=\"background-color:#225f78;color:#ffffff;padding:10px\">Model<\/th><th style=\"background-color:#225f78;color:#ffffff;padding:10px\">Use<\/th><\/tr><\/thead><tbody><tr><td><a href=\"https:\/\/ultrasuonindt.it\/en\/products\/thickness-gauges\/dakota-cmx10-dl-top-of-the-range-corrosion-gauge\/\">Dakota CMX10-DL<\/a><\/td><td>Extensive corrosion monitoring campaigns, scan at 250 readings\/sec<\/td><\/tr><tr><td><a href=\"https:\/\/ultrasuonindt.it\/prodotti\/misuratori-di-spessore\/dakota-cmx3-dl-corrosione-con-a-scan\/\">Dakota CMX3-DL<\/a><\/td><td>Corrosion with A-Scan and structured storage of points<\/td><\/tr><tr><td><a href=\"https:\/\/ultrasuonindt.it\/en\/products\/thickness-gauges\/dakota-mx2-dl-a-scan-b-scan-corrosion-gauge\/\">Dakota MX2-DL<\/a><\/td><td>A-Scan and B-Scan with 200 Hz scanning<\/td><\/tr><tr><td><a href=\"https:\/\/ultrasuonindt.it\/prodotti\/software-e-app\/dakmaster-gestione-dati-e-reportistica\/\">DakMaster<\/a><\/td><td>Organisation of grids by project, statistics and charts<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1757401201\"><strong class=\"schema-faq-question\">What is the difference between a grid and a sequential batch?<\/strong><p class=\"schema-faq-answer\">The sequential batch stores the readings one after another, in the order of acquisition. The grid arranges them in a matrix of rows and columns that reproduces the layout of the points on the component, and allows the result to be read as a map. <\/p><\/div><div class=\"schema-faq-section\" id=\"faq-question-1757401202\"><strong class=\"schema-faq-question\">Can points be added to a grid already in use?<\/strong><p class=\"schema-faq-answer\">Yes, but it is advisable to add them at the end, keeping the existing points and their coding unchanged. Renumbering points already measured makes previous campaigns non-comparable. <\/p><\/div><div class=\"schema-faq-section\" id=\"faq-question-1757401203\"><strong class=\"schema-faq-question\">How fine should the grid pitch be?<\/strong><p class=\"schema-faq-answer\">It depends on the type of degradation expected. Where thickness loss is localised a finer pitch is needed so as not to miss the minimum; where degradation is diffuse and uniform a wider pitch already describes the trend correctly. <\/p><\/div><\/div>\n\n<p class=\"wp-block-paragraph\">Back to <a href=\"https:\/\/ultrasuonindt.it\/en\/ndt-technologies-and-standards\/measurement-data-management\/\">Measurement data management<\/a> or write to us from the <a href=\"https:\/\/ultrasuonindt.it\/en\/contact\/\">Contacts<\/a> page.<\/p>\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h5 class=\"wp-block-heading\">Further information and contacts <\/h5>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><a href=\"http:\/\/www.roder.it\">Systems division and sensor integration partner : www.roder.it<\/a><br\/><a href=\"https:\/\/ultrasuonindt.it\/chi-siamo\/\">More information about RODER SRL : about us<\/a><br\/>Contact for general information : <a href=\"mailto:info@roder.it\">info@roder.it<\/a><br\/>Contact for information about these products : <a href=\"mailto:info@roder.it\">info@roder.it<\/a><\/p>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\"><br\/>The information contained on this web page is provided for information purposes only.
