Anwendung

Before connecting the PT640 to a direct injection fuel line, release fuel pressure, install batteries, select the correct adapter, and take precautions against residual fuel leakage.

Release Fuel Pressure

Unplug the fuel pump fuse, relay, or oil pump plug. Start the engine until it stalls, start it again 2-3 times, then disconnect the negative battery terminal.

Install Batteries

Open the rear battery cover and install 4 × 1.5V AAA batteries according to the positive and negative polarity marks.

Select Adapter

Choose the adapter suitable for the vehicle model and connect it to the measuring probe before connecting the pressure tester.

Connect To GDI Fuel Line

Connect the device to the direct injection fuel pipeline. Place a towel or cotton cloth below the oil pipe interface when removing the oil pipe to prevent residual fuel from leaking onto the ground.

Measure And Record

Long-press to power on, long-press zeroing, select the pressure unit, and start measurement. The device displays the fuel pressure value and related pressure data.

Anwendungshinweise

Release fuel pressure before installing the pressure tester.
Use a towel or cotton cloth to catch residual fuel when removing the fuel pipe.
Select the adapter suitable for the vehicle model before connection.
The device alarms when pressure exceeds 355bar.
Do not overload the equipment.
After measurement, power off the device at atmospheric pressure when possible.
