These probes were shipped in August and September 2022, and all have serial numbers starting with 0F3 and are running firmware version 5.1.0. All other serial numbers are unaffected (even if running firmware v5.1.0). Units from the 0F3 serial family shipped after Sept 26, 2022 do not exhibit the problem (they are running firmware v5.2.0). More details on determining whether a probe is affected can be found below.<\/p>\n<p class=\"wp-block-paragraph\"><strong>The solution:<\/strong> We have developed a Windows-based firmware update that resolves the problem. You may choose to apply the update yourself using <a href=\"https:\/\/www.vernier.com\/til\/16014\">these updater instructions<\/a> or Vernier can update them for you. If you prefer to send affected probes to Vernier for updating, complete <a href=\"https:\/\/www.vernier.com\/gdx-tmp-firmware\">this firmware update request form<\/a> to start the process. <\/p>\n<p class=\"wp-block-paragraph\"><strong>Details:<\/strong> To determine if a unit is affected, inspect the firmware version in Graphical Analysis. If the serial begins with 0F3 <strong>and<\/strong> the firmware version is 5.1.0 an update is needed. Other serial families may have version 5.1.0, but these are not affected by the error.<\/p>\n<p class=\"wp-block-paragraph\">On connecting a sensor you see the Sensors dialog. Confirm that the sensor is in the 0F3 series. <\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"728\" src=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-1024x728.png\" alt=\"\" class=\"wp-image-15971\" style=\"width:716px;height:509px\" srcset=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-1024x728.png 1024w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-600x426.png 600w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-768x546.png 768w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-1536x1091.png 1536w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-4-2048x1455.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Sensors dialog showing a GDX-TMP of the 0F3 series, as well as the location of the i button.<\/figcaption><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">Then click the i button to get to the details dialog. <\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"953\" height=\"1024\" src=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2-953x1024.png\" alt=\"\" class=\"wp-image-15969\" style=\"width:477px;height:512px\" srcset=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2-953x1024.png 953w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2-558x600.png 558w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2-768x825.png 768w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2-1430x1536.png 1430w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2022\/09\/image-2.png 1638w\" sizes=\"auto, (max-width: 953px) 100vw, 953px\" \/><figcaption class=\"wp-element-caption\">Device Information dialog showing firmware 5.1.0. <\/figcaption><\/figure>\n<\/div>\n<p class=\"wp-block-paragraph\">If the primary firmware is version 5.1.0, the unit requires an update. <\/p>","protected":false},"excerpt":{"rendered":"<p>The problem: A limited number of Go Direct\u00ae Temperature Probes were shipped containing a firmware version that results in spurious readings when the probe is&#8230;<\/p>\n","protected":false},"author":8976,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[],"class_list":["post-15964","post","type-post","status-publish","format-standard","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/15964","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/users\/8976"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/comments?post=15964"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/15964\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=15964"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=15964"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=15964"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
