主要特色
Live Negative-Pressure and Temperature Readout
Stated ±1% FS Accuracy
The built-in high-precision pressure sensor quickly captures pressure changes and provides real-time measurement results across the -101kPa to 0kPa working range with ±1%FS accuracy.
智慧溫度補償
The built-in temperature sensor monitors ambient temperature changes and automatically corrects measurement deviations, improving stability in -10°C to 60°C environments.
Direct Vehicle Power Supply
PT502 connects directly to the vehicle’s 12V power supply, providing worry-free power for continuous diagnosis without a separate internal battery.
反極性保護
If the positive and negative terminals are connected incorrectly, reverse polarity protection automatically cuts off current to help safeguard the gauge and vehicle battery.
Vacuum Fault Diagnosis
Follow the vacuum pattern at the selected connection to identify deviations that need further inspection, comparing readings under the same recorded engine conditions.
Main Cable Length
The main cable is 1.5 m long.

服務工作流程
Connect to the Documented Vacuum Path
步驟進展1 / 5
01
Choose the Test Path
Confirm the system, medium, expected range and required operating condition before selecting an adapter.
02
安全連接
Depressurize when required and install the correctly rated fitting, hose and sensor without forcing threads.
03
設定條件
Start or operate the system only as the vehicle procedure directs and watch for leaks at every connection.
04
Capture the Reading
Record the value, unit and operating condition; repeat the observation when the procedure calls for a comparison or decay period.
05
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.
安全使用
Match the Path, Adapter and Operating State
Vacuum Measurement Range
Vacuum range: -101 to 0 kPa. Choose a positive-pressure gauge for boost testing.
Do Not Power On Under Pressure
Do not turn on the vacuum pressure gauge while pressure is already applied. Powering on under pressure may affect zeroing and measurement accuracy.
Connect 12V Power Correctly
Connect the clamps correctly to the vehicle DC 10V–14V power supply. Reverse polarity protection helps protect the device, but correct connection is still required.
Confirm The Target System
Before testing, confirm that the target system is a vacuum / negative pressure system and that PT502’s -101kPa to 0kPa range is suitable.
利用結果規劃下次檢查
Use PT502 within its -101 to 0 kPa vacuum range and compare the pattern with the vehicle specification and operating condition to guide follow-up inspection.

壓力連結和閱讀問題
Can PT502 Measure Positive Pressure?
No. PT502 only supports negative pressure / vacuum pressure measurement. Do not use it for positive pressure testing.
PT502的測量範圍是多少？
PT502 measures vacuum pressure from -101kPa to 0kPa.
Why Should I Not Power On The Gauge Under Pressure?
Powering on while pressure is already applied may affect zeroing and cause inaccurate measurement results. Power on the gauge before applying vacuum pressure.
What Systems Can PT502 Test?
PT502 can be used for vacuum-related diagnosis in the intake manifold, crankcase, EGR / exhaust valve, exhaust pipe, gas pipeline, turbocharger vacuum line, and A/C ventilation system.
How Is PT502 Powered?
PT502 connects directly to the vehicle DC 10V–14V power supply using the battery clamps.
Does PT502 Have Reverse Polarity Protection?
Yes. PT502 has reverse polarity protection that cuts off current when the positive and negative terminals are connected incorrectly.
What Is The Accuracy Of PT502?
The measurement accuracy is ±1%FS across the working range.
Does PT502 Support Temperature Compensation?
Yes. PT502 has a built-in temperature sensor and smart temperature compensation to reduce measurement deviation caused by ambient temperature changes.
