It is suitable for airflow and temperature checks such as automotive AC outlets, ventilation systems, outdoor use, fan manufacturing, maritime operations, and wind energy applications.<\/p><p>TR401 measures local air speed and air temperature at its wind wheel, displays a Beaufort level, and provides a wind-chill warning under its trigger conditions. It does not directly calculate duct volume flow or diagnose an automotive A\/C fault.<\/p><\/div><\/details><details><summary>Which Wind Speed And Temperature Units Does TR401 Support?<\/summary><div class=\"autool-faq-answer\"><p>TR401 supports wind speed units m\/s, mph, km\/h, ft\/min, and knots. It supports temperature units \u00b0C and \u00b0F. Press the Unit key to switch wind speed units, and long press the Unit key to switch temperature units.<\/p><\/div><\/details><details><summary>What Batteries Does TR401 Use?<\/summary><div class=\"autool-faq-answer\"><p>TR401 uses 3 AAA 1.5V alkaline batteries. Insert the batteries according to the positive and negative marks inside the battery compartment. Replace them promptly when the low-battery icon appears, and remove the batteries before long-term storage.<\/p><\/div><\/details><details><summary>When Does The Wind Chill Warning Appear?<\/summary><div class=\"autool-faq-answer\"><p>The Wind Chill warning appears when the temperature is below 0\u00b0C and the wind speed is greater than 5m\/s. When the WINDCHILL signal appears, pay attention to low-temperature and high-wind conditions.<\/p><\/div><\/details><details><summary>How Do I Use Backlight, Data Hold, And Max\/Min Mode?<\/summary><div class=\"autool-faq-answer\"><ul><li>Press the power\/backlight key during operation to turn the backlight on or off.<\/li><li>Press the Data Hold key to lock or unlock the current displayed reading.<\/li><li>Press the measurement mode key to switch among real-time, Max, and Min reading modes.<\/li><\/ul><\/div><\/details><details><summary>Does TR401 Turn Off Automatically?<\/summary><div class=\"autool-faq-answer\"><p>Yes. During normal operation, TR401 automatically turns off after approximately 5 minutes of no key operation to save power.

For illuminance, choose TE301. For sound level, choose TN201. For temperature and humidity, choose TM101. TR401 is not a pressure tester or refrigerant leak detector.<\/p><\/div><\/details><details><summary>What Is Included In The TR401 Package?<\/summary><div class=\"autool-faq-answer\"><p>The TR401 package includes the digital anemometer main unit, three AAA batteries, wrist strap, retail box, and user manual.<\/p><\/div><\/details><details><summary>How Long Is The Warranty Support?<\/summary><div class=\"autool-faq-answer\"><p>Main unit: 3-year warranty. Standard accessories: 1-year warranty. <a href=\"https:\/\/autoolstore.com\/warranty-policy\/\" rel=\"noopener\" target=\"_blank\">Warranty Policy<\/a>.<\/p><\/div><\/details><details><summary>Does TR401 Measure Air Volume Or CFM?<\/summary><div class=\"autool-faq-answer\"><p>No direct duct-volume or CFM calculation is specified. TR401 measures local air speed in m\/s, mph, km\/h, ft\/min, or knots. Converting speed to volume flow requires a suitable area and traverse method.<\/p><\/div><\/details><details><summary>Can One Vent Reading Diagnose An A\/C Problem?<\/summary><div class=\"autool-faq-answer\"><p>No. Record vent, blower setting, vehicle state, ambient condition, measurement position, and repeated readings. Air speed and outlet-air temperature can show a repeatable symptom, while refrigerant charge, compressor, controls, doors, leaks, and other causes require the matching service procedure and tools.<\/p><\/div><\/details>\r\n<\/div>\r\n<\/div><\/section><\/main><\/div>\r\n\r\n<\/div>\r\n<!-- \/wp:post-content -->\r\n","protected":false},"excerpt":{"rendered":"<ul>\n<li><strong>0\u201330 m\/s Air Speed:<\/strong> Measure local air speed from 0 to 30 m\/s with 0.1 m\/s displayed resolution.<\/li>\n<li><strong>-10\u00b0C to 45\u00b0C Temperature:<\/strong> Read local air temperature from -10\u00b0C to 45\u00b0C at vents, fans, or outdoor points.<\/li>\n<li><strong>Five Air-Speed Units:<\/strong> Switch among m\/s, mph, km\/h, ft\/min, and knots, with \u00b0C or \u00b0F temperature display.<\/li>\n<li><strong>Max \/ Min + Data Hold:<\/strong> Track the highest or lowest observed value and freeze a current reading for recording.<\/li>\n<li><strong>Beaufort + Wind-Chill:<\/strong> View Beaufort force level 0\u201312 and receive a wind-chill warning below 0 \u00b0C when air speed exceeds 5 m\/s.<\/li>\n<\/ul>\n","protected":false},"featured_media":55131,"comment_status":"open","ping_status":"closed","template":"","meta":{"_gspb_post_css":""},"product_brand":[448],"product_cat":[1063],"product_tag":[1037,939,1038,953],"hf_cat_product":[4533,4535],"class_list":["post-43384","product","type-product","status-publish","has-post-thumbnail","product_brand-autool","product_cat-automotive-repair-testing-equipment","product_tag-best-seller","product_tag-multi-warehouse-shipping","product_tag-new-arrival","product_tag-workshop-diagnostic-tools","first","instock","shipping-taxable","purchasable","product-type-variable"],"meta_box":{"autool_archive_segment":"Workshop storage","autool_primary_use_case":"Workshop storage, rolling cart or mobile organization","autool_customer_focus":["warehouse \/ delivery location","workshop capacity and setup"],"autool_source_summary":"- Storage Workflow Simplified: Supports rolling storage and tool organization so buyers can judge layout fit and daily convenience quickly. - Decision Points Up Front: The short description is structured to surface pract","autool_model_family":"TR401","autool_voltage_options":"","autool_ship_from_options":"Germany\u3001United States\u3001United Kingdom\u3001China","autool_package_options":"","autool_accessory_options":"","autool_data_confidence":"site-content-derived","autool_manual_review_notes":""},"_links":{"self":[{"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product\/43384","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/comments?post=43384"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/media\/55131"}],"wp:attachment":[{"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/media?parent=43384"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_brand?post=43384"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_cat?post=43384"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_tag?post=43384"},{"taxonomy":"hf_cat_product","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/hf_cat_product?post=43384"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
