class=\"autool-faq-answer\"><p>AUTOOL PT640 is used for GDI \/ direct injection fuel pressure testing. It is designed to measure fuel injection pump pressure in automotive direct injection systems.<\/p><\/div><\/details><details><summary>What Pressure Range Does PT640 Support?<\/summary><div class=\"autool-faq-answer\"><p>PT640 supports a pressure range of 0-360bar \/ 0-5221.3psi \/ 0-367kg\/cm\u00b2. The overload pressure is 400bar, and the device alarms when pressure exceeds 355bar.<\/p><\/div><\/details><details><summary>Which Pressure Units Can PT640 Display?<\/summary><div class=\"autool-faq-answer\"><p>PT640 can display pressure in bar, kg\/cm\u00b2, and Psi. The unit button allows switching between these pressure units.<\/p><\/div><\/details><details><summary>How Do I Release Fuel Pressure Before Testing?<\/summary><div class=\"autool-faq-answer\"><p>Unplug the fuel pump fuse, relay, or oil pump plug, then start the engine until it stalls. Start it again 2-3 times, then disconnect the negative battery terminal before connecting the tester.<\/p><\/div><\/details><details><summary>What Batteries Does PT640 Use?<\/summary><div class=\"autool-faq-answer\"><p>PT640 uses 4 \u00d7 1.5V AAA batteries. Open the rear battery cover and install the batteries according to the positive and negative polarity marks.<\/p><\/div><\/details><details><summary>What Is The Difference Between PT635 And PT640?<\/summary><div class=\"autool-faq-answer\"><p>PT635 is a high-end fuel pressure gauge for broader fuel pressure service. PT640 is specifically positioned as a GDI fuel pressure gauge for automotive direct injection system fuel pump pressure testing with a 0-360bar range.<\/p><\/div><\/details><details><summary>Why Should I Use The Correct Adapter?<\/summary><div class=\"autool-faq-answer\"><p>The correct adapter helps connect the PT640 measuring probe securely to the vehicle\u2019s direct injection fuel pipeline. Using an unsuitable adapter may affect sealing, measurement accuracy, or safe connection.<\/p><\/div><\/details><details><summary>Does PT640 Include A Manual?<\/summary><div class=\"autool-faq-answer\"><p>Yes.
