Compare that value with the applicable fluid and vehicle service criterion as one maintenance input.<\/p><\/div><\/details><details><summary>Which Brake Fluid Types Does AS506 Support?<\/summary><div class=\"autool-faq-answer\"><p>Select the procedure-confirmed DOT3, DOT4 or DOT5.1 operating mode before testing.<\/p><\/div><\/details><details><summary>What Is The Difference Between Normal Mode And Brand Mode?<\/summary><div class=\"autool-faq-answer\"><p>Normal Mode lets you select the brake fluid type directly. Brand Mode lets you select from built-in brand references including ATE, TRW, BOSCH, MOBIL, TOTAL, FUCHS, MOTUL, DELPHI, KUNLUN, FERODO, BREMBO, TEXTAR, MONARCH, and CHANGCHENG, then choose the matching brake fluid type.<\/p><\/div><\/details><details><summary>How Much Brake Fluid Should I Use For One Test?<\/summary><div class=\"autool-faq-answer\"><p>Use the injection sampler to fill the beaker with brake fluid above the 40ml scale and not more than 50ml. Do not test with insufficient liquid, because empty boiling may damage the test stick.<\/p><\/div><\/details><details><summary>What Power Supply Does AS506 Need?<\/summary><div class=\"autool-faq-answer\"><ul><li>Use 12V vehicle battery power.<\/li><li>The working voltage is 12V and the minimum voltage is 10V.<\/li><li>Connect the red clamp to battery positive and the black clamp to battery negative.<\/li><li>Use AS506 only with the supported 12 V power connection.<\/li><\/ul><\/div><\/details><details><summary>How Long Does One Detection Take?<\/summary><div class=\"autool-faq-answer\"><p>After selecting the correct mode and brake fluid type, press and hold the S button for about 16 seconds. Wait for the progress bar to complete, then read the test result on the OLED screen.<\/p><\/div><\/details><details><summary>Can I Pour Tested Brake Fluid Back Into The Reservoir?<\/summary><div class=\"autool-faq-answer\"><p>No. Do not pour the tested brake fluid back into the brake fluid reservoir. The sample has been boiled and its structure has changed, which may affect driving safety.<\/p><\/div><\/details><details><summary>How Should I Clean Or Maintain The Test Stick?<\/summary><div class=\"autool-faq-answer\"><p>After testing, empty the brake fluid and fill about 50ml of water to clean residual brake fluid from the test stick. If the tester will not be used for a long time, use water to dilute and remove residual brake fluid, then let the heating stick dry at room temperature.<\/p><\/div><\/details><details><summary>How Can I Check Whether AS506 Needs Calibration?<\/summary><div class=\"autool-faq-answer\"><p>Fill the beaker with water and test whether the boiling point reads around 100\u00b0C \/ 212\u00b0F \u00b13%. This is only a quick initial diagnosis. If stricter standards are required, the unit must be returned to the factory for retesting and calibration.<\/p><\/div><\/details><details><summary>How Is AS506 Different From AS501, AS502, AS503, AS505, And AS507?<\/summary><div class=\"autool-faq-answer\"><ul><li>AS501 and AS502 focus on brake fluid water content.<\/li><li>AS503 tests engine oil quality by transmittance.<\/li><li>AS505 tests transmission fluid by transmittance.<\/li><li>AS506 tests brake fluid boiling point using flash point heating technology.<\/li><li>AS507 tests power steering fluid by transmittance.<\/li><\/ul><\/div><\/details><details><summary>What Accessories Are Included?<\/summary><div class=\"autool-faq-answer\"><p>Package contents: AS506 main tester, carrying case, beakers, injection sampler, hose, user manual, and retail box.<\/p><\/div><\/details><details><summary>How Long Is The Warranty?<\/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>\r\n<\/div>\r\n<\/div><\/section><\/main><\/div>\r\n\r\n","protected":false},"excerpt":{"rendered":"<ul>\n<li><strong>Heated Boiling-Point Test:<\/strong> Heat a prepared brake-fluid sample and report its boiling point for comparison with the applicable service reference.<\/li>\n<li><strong>DOT3 \/ DOT4 \/ DOT5.1:<\/strong> Select a test mode for DOT3, DOT4, or DOT5.1 brake fluid.<\/li>\n<li><strong>Normal + 14-Brand Modes:<\/strong> Choose a general fluid-type test or one of 14 supported brand references.<\/li>\n<li><strong>About 16 Seconds:<\/strong> Follow live temperature and progress on the OLED during the approximately 16-second test cycle.<\/li>\n<li><strong>Reusable Test Hardware:<\/strong> Run repeated sample tests without disposable test strips, using an external 12 V battery supply.<\/li>\n<\/ul>\n","protected":false},"featured_media":54842,"comment_status":"open","ping_status":"closed","template":"","meta":{"_gspb_post_css":""},"product_brand":[448],"product_cat":[1063,1068],"product_tag":[956,940,939],"hf_cat_product":[4540],"class_list":["post-32627","product","type-product","status-publish","has-post-thumbnail","product_brand-autool","product_cat-automotive-repair-testing-equipment","product_cat-oil-analysis-tester","product_tag-fluid-testing","product_tag-measurement-tools","product_tag-multi-warehouse-shipping","first","instock","shipping-taxable","purchasable","product-type-variable"],"meta_box":{"autool_archive_segment":"Pressure testing","autool_primary_use_case":"Pressure testing for engine, fuel, air or cooling systems","autool_customer_focus":["measurement accuracy","warehouse \/ delivery location"],"autool_source_summary":"- Pressure Checks Made Clear: Built for targeted pressure diagnosis in fuel, oil, cooling, or air systems where confirmation matters before repair. - Decision Points Up Front: The short description is structured to surfa","autool_model_family":"AS506","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\/32627","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=32627"}],"wp:attachment":[{"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/media?parent=32627"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_brand?post=32627"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_cat?post=32627"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/product_tag?post=32627"},{"taxonomy":"hf_cat_product","embeddable":true,"href":"https:\/\/autoolstore.com\/wp-json\/wp\/v2\/hf_cat_product?post=32627"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
