class=\"autool-faq-grid\">\r\n<details><summary>What Is AUTOOL PT635 Used For?<\/summary><div class=\"autool-faq-answer\"><p>AUTOOL PT635 is used for automotive fuel system pressure checks and fuel temperature monitoring. It is suitable for users who need to read real-time pressure, maximum pressure, minimum pressure, average pressure, fuel temperature, and measurement time on one digital display.<\/p><\/div><\/details><details><summary>What Is The Difference Between PT630 And PT635?<\/summary><div class=\"autool-faq-answer\"><p>Both PT630 and PT635 are for automotive fuel system pressure checks. PT635 is the higher-end option, with broader adapter coverage shown as 31 types in the comparison chart and added fuel temperature monitoring, making it better for users who want more complete fuel system checking capability.<\/p><\/div><\/details><details><summary>Is PT635 Suitable For GDI High-Pressure Fuel Systems?<\/summary><div class=\"autool-faq-answer\"><p>PT635 is for standard automotive fuel system pressure checks. If you need to test gasoline direct injection high-pressure fuel pump pressure, compare PT640 instead, because PT640 is the GDI fuel pressure gauge with a much higher pressure range.<\/p><\/div><\/details><details><summary>What Pressure Range And Units Does PT635 Support?<\/summary><div class=\"autool-faq-answer\"><p>PT635 displays pressure in PSI, bar, and kg\/cm\u00b2. The product image lists 0-426.6 psi, 0-30 kg\/cm\u00b2, and 0-29.4 bar, while the manual technical specification lists a 0-30 bar range. The display resolution is 0.01.<\/p><\/div><\/details><details><summary>Does PT635 Measure Fuel Temperature?<\/summary><div class=\"autool-faq-answer\"><p>Yes. PT635 supports fuel temperature display, and temperature units can be switched between Celsius and Fahrenheit. This helps users observe pressure and temperature changes during fuel system checks.<\/p><\/div><\/details><details><summary>What Information Is Shown On The Display?<\/summary><div class=\"autool-faq-answer\"><p>The 2.8-inch display can show current pressure, pressure units, current maximum pressure, current minimum pressure, current average pressure, current temperature, temperature unit, and current measurement time.<\/p><\/div><\/details><details><summary>Can PT635 Save Test Data?<\/summary><div class=\"autool-faq-answer\"><p>PT635 supports reading lock, interface lock, and data clearing. Confirm the current storage function with support if multi-record logging is required.<\/p><\/div><\/details><details><summary>What Battery Does PT635 Use?<\/summary><div class=\"autool-faq-answer\"><p>PT635 uses 6V operating voltage from four 1.5V AAA batteries. Open the battery cover on the back of the device, insert the batteries with the correct polarity, and close the cover securely before use.<\/p><\/div><\/details><details><summary>How Do I Start And Zero The PT635?<\/summary><div class=\"autool-faq-answer\"><p>Long press the power button for more than 2 seconds to start the instrument. Before testing, long press the zero function so the real-time pressure display returns to zero.<\/p><\/div><\/details><details><summary>What Are The Basic Operation Steps?<\/summary><div class=\"autool-faq-answer\"><p>Disconnect the engine fuel pipeline interface, connect the correct vehicle adapter to the measuring probe, reset pressure to zero, connect the measuring probe to the engine, start the engine, then read the measured pressure on the gauge.<\/p><\/div><\/details><details><summary>What Accessories Are Included?<\/summary><div class=\"autool-faq-answer\"><p>Package contents: PT635 main unit, carrying case, product box, user manual, measuring probe, fuel hoses, adapters, connectors, and related accessories.<\/p><\/div><\/details><details><summary>What Should I Check During Maintenance?<\/summary><div class=\"autool-faq-answer\"><p>Regularly check parts that need tightening and connection. If anything is loose, tighten it in time. Avoid contact with corrosive liquids, do not store the tool in hot, humid, or non-ventilated places, and keep the product dry when not in use.<\/p><\/div><\/details><details><summary>Will PT635 Turn Off Automatically?<\/summary><div class=\"autool-faq-answer\"><p>Yes. The manual notes that the device can automatically power off after 5 minutes of inactivity when no pressure is being applied. After measurement, it can also be shut down by long pressing the power button for about 2 seconds under atmospheric pressure.<\/p><\/div><\/details><details><summary>How Long Is The Warranty?<\/summary><div class=\"autool-faq-answer\"><p>Main unit: 3-year warranty.
