This part of ISO 17123 is applicable to reflector-type EDM instruments<\/p>\n<p>only and is not designed to determine the precision of non-prism EDM types. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand and to satisfy the requirements of other standards. They are not proposed as tests for acceptance or performance evaluations<\/p>\n<p>that are more comprehensive in nature.<\/p>\n<p>This part of ISO 17123 can be thought of as one of the first steps in the process of evaluating the uncertainty of a measurement (more specifically a measurand). The uncertainty of a result of a measurement is dependent on a number of parameters. Therefore we differentiate between different measures of accuracy and objectives in<\/p>\n<p>testing, like repeatability, reproducibility (e.g. between day repeatability), and of course a thorough assessment of all possible error sources, as prescribed by ISO\/IEC Guide 98-3 and by ISO 17123-1.<\/p>\n<p>These field procedures have been developed specifically for <i>in situ <\/i>applications without the need for special ancillary equipment and are purposefully designed to minimize atmospheric influences.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Optics and optical instruments \u2014 Field procedures for testing geodetic and surveying instruments \u2014 Part 4: Electro-optical distance meters (EDM measurements to reflectors)<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2012-06<\/td>\n<td>30<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":598550,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[276,2634],"product_tag":[],"class_list":{"0":"post-598540","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-17-180-30","7":"product_cat-iso","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/598540","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/598550"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=598540"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=598540"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=598540"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
