This is particularly helpful for <a href=\"https:\/\/www.alicat.com\/products\/gas-flow\/mass-flow-controller\/low-pressure-drop-mass-flow-controllers\/\">Whisper mass flow controllers<\/a> as it helps protect the sensitive differential pressure sensor from unforeseen changes in upstream or downstream pressure.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<table border=\"1\" style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td width=\"107\" style=\"width: 57.6052%;\"><strong>Features<\/strong><\/td>\n<td width=\"64\" style=\"width: 42.0712%;\"><strong>Menu location<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">AUTO TARE<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; TARES<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">CONTROL SETUP<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; CONTROL<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">DEVICE UNITS<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; BASIC CONFIG<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">DIAG TEST<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ABOUT &gt; DEVICE STATE<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">FLOW AVG<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; SENSOR SETUP<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">GAS SELECT<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; BASIC CONFIG &gt; GAS<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">LCD CONTRAST<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; DISP SETUP<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">MFG DATA<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ABOUT &gt; MFG INFO<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">MODEL INFO<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ABOUT &gt; DEVICE INFO<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">PRESS AVG<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; SENSOR SETUP<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">ROTATE DISP<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; DISP SETUP<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">RS232 COMM<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; COMM SETUP<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">STP\/NTP<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; BASIC CONFIG<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">TARE P w\/BARO<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; TARES &gt; TARE PRESS<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 57.6052%;\">ZERO BAND<\/td>\n<td style=\"width: 42.0712%;\">MENU &gt; ADV SETUP &gt; SENSOR SETUP<\/td>\n<\/tr>\n<\/tbody>\n<\/table>[\/et_pb_accordion_item][\/et_pb_accordion][et_pb_text _builder_version=&#8221;4.27.0&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]Keep reading for older firmware version updates, or <a href=\"https:\/\/www.alicat.com\/contact\/\">contact an applications engineer<\/a> with additional questions.\n\n&nbsp;\n<h2 id=\"7v\"><strong>7v firmware updates<\/strong><\/h2>[\/et_pb_text][et_pb_accordion _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; toggle_font=&#8221;|700|||||||&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_accordion_item title=&#8221;Which instruments are affected by this change?&#8221; open=&#8221;on&#8221; _builder_version=&#8221;4.24.3&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<p>Most devices shipped between June 2021 May 2017 have 7v firmware.<\/p>\n<p><strong>Exception:<\/strong><\/p>\n<ul>\n<li>No-change customers<\/li>\n<\/ul>[\/et_pb_accordion_item][et_pb_accordion_item title=&#8221;Can I update my existing instruments to 7v?&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221; open=&#8221;off&#8221;]Alicat\u2019s 7v firmware update is compatible with most Alicat instruments that have serial numbers of 135,000 or higher.
