Logger <i>Pro<\/i> 3.8.2 produces some potentially confusing dialogs that must be correctly navigated to achieve the desired setup. There may be changes in future versions of Logger <i>Pro<\/i>. <\/p>\n<p>*Use the BTA cable to connect the Power Amp to the ch 4 input of LabPro. Connect any other analog sensors you will use at this time.<br \/>\n*Turn on the Power Amp to make the current sensor signal present on the LabPro. Don&#8217;t turn off the Power Amp to avoid losing the current sensor.<br \/>\n*Launch Logger <i>Pro<\/i>. A current sensor in ch 4 will be detected.<br \/>\n*Choose Set Up Sensors &#8211;> LabPro from the Experiment menu to open the sensors dialog.<br \/>\n*Click the ch 4 drop down menu (which currently has the PAMP photo in place) and choose Analog Out&#8230;<br \/>\n*In the Analog Out dialog set up the output as desired.<br \/>\n*Click OK to dismiss the Analog Out dialog.<br \/>\n*At this point you&#8217;ll get a dialog that is potentially confusing. The dialog states that &#8220;Analog Out is only available on a Voltage Probe&#8230;&#8221; and &#8220;Would you like to treat the existing sensor as a raw +\/- 10V probe?&#8221; The correct answer in this case is No. This will leave the current sensor in place, but will still enable Analog Out.<br \/>\n*Now configure data collection rate and duration as desired. <\/p>\n<p>The analog out will already be on at this point. Collect data as desired. <\/p>\n<p>If you save out the Logger <i>Pro<\/i> session as an experiment file (a cmbl file), note that when you open this file at a later time, you will get a dialog box about analog out being compatible only with a voltage probe, and would you like to substitute a voltage probe on ch4. Again, the correct answer in this case is No. <\/p>\n<p>See also &#8220;<a href=\"\/til\/2017\/\">An experiment using the current sensor of the power amplifier (PAMP) gives unexpected results<\/a>&#8221; for important information on using the current sensor in the Power Amplifier. <\/p>","protected":false},"excerpt":{"rendered":"<p>The current sensor function of the can be used at the same time as the analog out function of LabPro, but the procedure is not&#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":[1467,3525,3524,1652],"class_list":["post-2160","post","type-post","status-publish","format-standard","hentry","tag-analog-out","tag-current-sensor-voltage-probe","tag-labpro-logger-pro","tag-pamp"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/2160","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=2160"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/2160\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=2160"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=2160"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=2160"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
