P150 – Vehicle Electrical System Circuit Tester
The P150 is an electrical tester for 6 to 30 volt vehicle electrical system diagnostics, featuring simple operation and wide practicality. It combines 14 diagnostic functions into one compact handheld device, making automotive electrical troubleshooting fast and efficient.
Key Functions
-
Intelligent Testing– No need to select the mode after switching on. It can quickly detect the voltage, resistance, and diode in the wiring of the vehicle electrical system automatically.
-
Voltage Testing– DC voltage measurement (BAT reference + live reading with MAX/MIN tracking).
-
Flexible Testing (AC Mode)– Flexibly tests voltage, frequency, duty cycle, and fuel injection nozzle. Automatically draws waveform signals with simple mode switching. Displays VAC waveform and Fuel inject waveform.
-
Frequency Measurement– 10Hz~200KHz range.
-
Duty Cycle– 1–99% duty cycle measurement.
-
Injector Test– Tests fuel injection nozzle signals.
-
Resistance Testing– 0.1Ω~200KΩ range.
-
Diode Testing– 0.2V~2.6V range.
-
Circuit Breaker– Short-circuit protection function. If overloaded, the internal circuit breaker automatically trips to protect safety. Trip current: 8A for 1 hour / 12A less than 1 hour / 16A less than 5 seconds.
-
Positive and Negative Detection– Identifies polarity of circuit connections.
-
Continuity Test– Quickly checks whether an automotive circuit system is on or off.
-
Trace Locate Short Circuit– Locates short circuit positions in wiring.
-
Jumper Lead Function– Provides jumper lead capability for circuit testing.
-
Component Activation– Activates start fuel pumps, solenoids, blowers, cooling fans, headlights, and other components.
-
Ground Detection– Tests ground connections in vehicle electrical systems.
