A calibration correction data sheet is provided with the standard resistor, and the corrections in the table are given at 0.5\u00b0C temperature intervals, using which the uncertainty can be reduced.<\/p>\n<h2>Used in air, no need to use an oil bath<\/h2>\n<p>The 742A can be used in air without the use of a troublesome oil bath. Its temperature stability allows it to operate within a temperature range of 18\u00b0C to 28\u00b0C.<\/p>\n<h2>Compact and robust<\/h2>\n<p>The 742A is compact, rugged and easy to use. Resistance changes due to temperature and mechanical vibration are greatly minimized.<\/p>\n<p>The 742 standard resistors include 12 resistance values from 1\u03a9 to 19M\u03a9.<\/p>\n<ul>\n<li>Provides temperature characterization corrections<\/li>\n<li>Airborne use, no oil bath required<\/li>\n<li>compact and sturdy<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<h2 class=\"features-title\">Main characteristics<\/h2>\n<div id=\"keyfeature_content\">\n<ul>\n<li>Highly accurate working standards for field resistance calibration.<\/li>\n<li>Small, sturdy and easy to transport.<\/li>\n<li>Temperature stability and six-month stability up to 2.5 ppm.<\/li>\n<li>Temperature range: 18\u00b0C to 28\u00b0C.<\/li>\n<li>Designed to minimize resistance changes caused by thermal and mechanical shocks.<\/li>\n<\/ul>\n<\/div>","protected":false},"featured_media":14986,"comment_status":"open","ping_status":"closed","template":"","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false},"product_brand":[3528],"product_cat":[3977],"product_tag":[],"class_list":{"0":"post-14193","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-fluke","7":"product_cat-standards","9":"first","10":"instock","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product\/14193","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/comments?post=14193"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media\/14986"}],"wp:attachment":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media?parent=14193"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_brand?post=14193"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_cat?post=14193"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_tag?post=14193"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
