With setpoint ramping, you can set a maximum speed at which a mass flow or pressure controller flows until the setpoint is achieved. Setpoint ramping can be performed using either the <a href=\"https:\/\/www.alicat.com\/support\/digital-displays\/\" target=\"_blank\" rel=\"noopener\">front display<\/a> or <a href=\"https:\/\/www.alicat.com\/support\/communication-options-for-alicat-instruments\/\" target=\"_blank\" rel=\"noopener\">serial commands<\/a>.<\/p>\n<p>Setpoint ramping is commonly used to ensure safety, by ramping up pressure or flow in a controlled, observable way. Setpoint ramping can also be configured to only apply to flow\/pressure in a single direction for situations where you may need to quickly zero pressure or flow during an emergency.<\/p>\n<p>To enable and edit the setpoint ramp functionality on your device, follow the instructions below.<\/p>\n<h2>Video tutorial<\/h2>\n<p><iframe title=\"Alicat Mass Flow Controller: Tutorial - Setpoint Ramp\" width=\"1080\" height=\"608\" src=\"https:\/\/www.youtube.com\/embed\/rOoQ-SGqdXU?feature=oembed&rel=0\"  allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.23.1&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<h2>Step-by-step instructions (front panel)<\/h2>\n<ol>\n<li>Press the bottom right button for \u201cMENU\u201d selection.<\/li>\n<li>Press the top left button for \u201cCONTROL\u201d selection.<\/li>\n<li>Press the top left button for \u201cSETPT RAMP\u201d selection.<\/li>\n<li>Press the top left button for \u201cDELTA\u201d selection.<\/li>\n<li>Use the up, down, and select digit buttons to set your desired delta.<\/li>\n<li>Press the bottom right button for \u201cSET\u201d selection.<\/li>\n<li>Press the top right button for \u201cTIME\u201d selection.<\/li>\n<li>Use the up, down, and select digit buttons to set your desired time.<\/li>\n<li>Press the bottom right button for \u201cSET\u201d selection.<\/li>\n<li>Press the top middle button for \u201cTIME UNITS\u201d selection.<\/li>\n<li>Use the up and down buttons to select your desired time units. <em>Note:\u00a0 This will NOT change the rate, and it will automatically update the current rate to the newly selected units.<\/em><\/li>\n<li>Press the bottom right button for \u201cSET\u201d selection.<\/li>\n<\/ol>[\/et_pb_text][et_pb_accordion _builder_version=&#8221;4.23.1&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_accordion_item title=&#8221;Video transcript&#8221; open=&#8221;on&#8221; _builder_version=&#8221;4.23.1&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<p>\u201cMy name is Marina Palese, and I\u2019m an App Engineer at Alicat Scientific.\u00a0 Today I\u2019m going to show you how to set up setpoint ramping.\u00a0 Let\u2019s get started.\u201d<\/p>\n<p>To give a setpoint ramp to your device, we\u2019re going to to MENU (bottom right button), CONTROL (top left button), SETPT Ramp (top left button), and from here we can set our DELTA (top left button).\u00a0 This is how much we want the flow to change in this ramp, and we can set that to whatever value we like (ex. 100 SLPM).<\/p>\n<p>At this point the display will read \u201cCurrent Max Ramp Rate -None- SLPM\/s\u201d.<\/p>\n<p>The TIME (top right button) will be the amount of delta over time.\u00a0 Let\u2019s say we want to change 100 SLPM per one second.<\/p>\n<p>At this point the display will read \u201cCurrent Max Ramp Rate 99.99999 SLPM\/s\u201d.<\/p>\n<p>And then we can set out units (top middle button).\u00a0 Let\u2019s say we change these to hours.\u00a0 Then, the current ramp rate will automatically adjust to whatever the time unit is.<\/p>\n<p>Finally, the display will read \u201cCurrent Max Ramp Rate 360000 SLPM\/hour\u201d.<\/p>[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"featured_media":46458,"parent":0,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"1920","content-type":"","_searchwp_excluded":""},"categories":[],"class_list":["post-38056","support","type-support","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.5 (Yoast SEO v27.5) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Setpoint Ramping Tutorial - Alicat Scientific<\/title>\n<meta name=\"description\" content=\"Alicat controllers come equipped with a setpoint ramping feature that allows them to ramp up and\/or down to changes in setpoint.
