Service Workflow
Zero, Connect and Compare Both Sides
Choose the Test Path
Confirm the system, medium, expected range and required operating condition before selecting an adapter.
Connect Safely
Depressurize when required and install the correctly rated fitting, hose and sensor without forcing threads.
Set the Condition
Start or operate the system only as the vehicle procedure directs and watch for leaks at every connection.
Capture the Reading
Record the value, unit and operating condition; repeat the observation when the procedure calls for a comparison or decay period.
Depressurize and Confirm
Return the system to a safe state, remove the adapter, restore the connection and confirm the next diagnostic step against the vehicle specification.
Safe Use
Secure the Vehicle and Pneumatic Connections
Air Suspension Tester
PT680 is designed for air suspension system pressure leak testing, including air springs, pipes, and connection points.
Not An Engine Pressure Tester
PT680 is different from engine cylinder, engine oil, fuel, transmission oil, and brake pressure testers. Use the correct AUTOOL pressure tester for each system.
Check Adapter Fitment
Before testing, confirm that the included hoses, adapters, and fittings can connect properly to the target vehicle air suspension system.
Use Within Rated Range
Use PT680 within its 0-20Bar measurement range and -10°C to 60°C operating temperature range.
Power and Interface Details
Power PT680 with 4 × 1.5V AAA batteries, and use the Type-C interface only as described in the instructions supplied with the selected unit.
Compare Air-Suspension Pressure Channels
Use the specified air-suspension adapters and compare both pressure channels with valve state, load, and temperature controlled. Use any pressure decay to guide a focused leak inspection.
